Re: Pathephone Model 100
Thanks.
I found the volume rod early; it wasn't quiet enough for Mom, hence the addition of the shirt.
I heard about the needle thing early as well, and haunted shops looking for NOS needles. Eventually I also got two NOS sapphire styli, but have never used them. I now know sources for new manufactured steel needles.
I own Pathe records, and more lateral-cut (what I call RCA-style) records, but the box is under other boxes at the moment. The several that were still in the cabinet when we moved it from my parents' house were moved separately and then put back, including the one on the turntable (The Star-Spangled Banner/Columbia, the Gem of the Ocean).
The only real issue I have is how to rotate the reproducer. I'm leery of just yanking on it.
I'll be seeking motor maintenance next, I suppose. I transported it for weight's sake with the motor platform out of it and noticed grease outside of part of it. It didn't look right but it works and I have a “leave well enough alone” approach to unknown objects, especially if they seem to be operating nominally!
Thanks for your response and further advice.

Hi, David,
Glad I could offer some insights. These old machines are lots of fun. Interesting thing about Pathe: in Europe, the company seems to have offered a wide array of sometimes eccentric designs, but here in the States nearly all its machines seem to have been half-cabinet uprights with straight sides, about as basic a profile as one could imagine. At first glance, most are pretty hard to tell apart, and I'm sure that figures into the distinct lack of enthusiasm they seem to draw from the collectors' market. Of course, being designed to play a special vertical cut record probably doesn't help, either, although I can state with the authority of having played mine like crazy as a kid that they do just fine with steel needle laterals, too.

Incidentally, on the subject of Pathe records, I should mention that Pathe was just as eccentric in their production as it was in some of its designs for machines. Unlike most companies, which recorded by the method we today call "direct to disk," Pathe recorded everything to large diameter cylinders and then dubbed them mechanically to the form in which they would issue, be it standard cylinder, larger-diameter "inter" cylinder, vertical cut sapphire disc (in sizes ranging from maybe 8" or so up to 14" for home play and 20" for some records intended for playback in commercial establishments), or lateral needle cut disc. Sometimes records labeled as having the same recording can have different amounts of music depending on when the "daughter" blank ran out of space relative to the master cylinder.
Thanks for writing back with the extra information. I hope you'll have as many hours of pleasure with your machine as I've had with mine over the years.
Best regards

UBYTE speaker cables really worth making!
Dear Lucio,
Thank you for how much you have helped me through the free information available on the TNT-Audio website! I recently ended up having to use ancient 79 strand cables with 2mm diameter copper conductors for my speakers (long story!), but knew there was better. A year ago I bought 25m of CT100 coax cable with solid centre conductor and copper foil and successfully made UBYTE-I interconnects, although without soldering as I found the copper foil fragile. I doubted I could make the TNT UBYTE-2 speaker cables described by Thorsten Loesch but fancied making his far simpler original UBYTE ones, described on the same page.
Even with the PVC insulation, they are far superior to the ancient 79 strand in terms of detail (and I suspect frequency response) and were not difficult to make. I attach an instructional photo which might help others. I gently twisted the two conductors, as per John M Risch's method, and applied a cable tie every 2 feet.
For a 4.5m length I get 4.4uH inductance, 711pF parallel capacitance and 0.078 Ohms loop resistance. The 4mm plugs I used were not expensive, so I guess everything was less than UKP20, perhaps even less than UKP15.
Many thanks again for supporting the TNT-Audio website!
Kind regards,

Dear Phil,
many thanks for your kind and precious feedback on our DIY speaker cables design! I'm glad you've found the UByte2s so good in your system. And yes, cables do influence the sound and our DIY route is the less expensive way to experiment their effect on a system. We have many more DIY designs, for mains cables, interconnects, even USB cables, feel free to experiment and report back. Thanks for the clear step by step procedure!
Thanks for the feedback!

Pathephone Model 100
I have just been reading a web page from April, 2013, about your Pathephone Model 100. Hoping your email address is still actively monitored! I have one of these, which came to me via a circuitous route from a great-grandfather who died the year I was born. It was placed in my bedroom when I was a teenager, and I was fascinated by it. When my parents' house was emptied for sale, I got it again, and now stays in my guest bedroom. I have made a slow start of showing it off on youtube, here.
You'll see that it seems identical to yours, down to the scrollwork on the front. I'd be interested in tapping your expertise on the subject.
Bests,
David - E-mail: dbaker1066 (at) hotmail.com

Hi, David,
What a pleasure to hear from a fellow owner of a Pathephone, another who had it in his room as a teenager at that! Must be a "David" thing. I don't know which article you saw--maybe this one?--but a photo of my machine in my corresponding bedroom is here. I wish my Pathe had the kind of family history yours does, though; I got mine from a flea market when I first got interested in old records. It's always special when a machine has come down through the family.
Yes, we have the same model, although mine is in mahogany and yours in oak. In that you are lucky; mahogany was more fashionable and sold better back when these machines were new, meaning oak is less often encountered today--and hence a little more desirable to collectors, not that upright "conventional" Pathe machines are exactly in hot collector demand in either wood. (Some of the more exotic designs are another story.) Your video confirmed something I've long suspected: somewhere along the line, somebody cut one bar from the center of my grille, probably because it got damaged. I couldn't tell about yours for sure, but I'd guess it has its original finish. Mine--which, by the way, is sitting about six feet from me--is refinished to the taste of the '70s in a dull "penetrating" type finish, not the glossy varnish or shellac that would originally have graced the cabinet. Oh, well, at least it isn't something that screams "wrong" like polyurethane!

I have a few hints for you. First, about that tee shirt: you don't need it to dampen the volume. If you look at the left side of the machine, toward the back you should see a knob or, if it's missing, the threaded tip of a thin metal rod. That's a volume control. Pull it straight out, and a little wooden shutter will slide across the throat of the machine's internal horn to cut the volume.

Second, the reproducer probably needs rebuilding, which sounds drastic but actually is mostly a process of replacing the rubber gasket tubing that holds the diaphragm in place. Old natural rubber tubing gets hard over the decades, and once it loses pliability the machine's sound becomes harsh and distorted. I wouldn't be surprised if that was why your mother objected that your machine was "too loud." One good source for information about how to rebuild a reproducer yourself and the names of third parties who, if you prefer, can do it for you inexpensively is the Talking Machine Forum.

Third, if you are playing records with steel needles (as is appropriate for lateral cut records--for more, see here), be sure to change the needle with each record side. Lateral 78s incorporated an abrasive into the material to shape steel needles to their grooves, and once so shaped a needle will damage any other groove it encounters. Packs of steel needles are readily available from sources like eBay. If your machine came to you with any vertical cut Pathe discs, don't play them with steel needles, which will destroy them; you need a sapphire ball stylus, again something you can turn up on eBay or from specialist dealers. Pathe discs marked "Actuelle" are lateral cut and OK with steel needles, however. The Pathephone, by the by, has a "universal" reproducer, set in such a way that it will play both vertical and lateral cut discs; you can rotate it in the tonearm to optimize it for either type. Be careful, though--don't try to force it, as the tonearm may well be of pot metal that has swollen and frozen the reproducer in place, in which case too much force will break the tonearm.

Fourth and finally, consider servicing the motor or having it serviced to clean off and replace the old grease, which by this late date almost certainly is too gunky and dirty to provide proper lubrication, risking needless wear to the gears and bearings and whatnot.
There are a few tips to get you started.
Happy listening, and thanks for writing!

Phono preamps
Hi Arvind and Richard, I trust you are both well. I wonder if you can help me narrow down a choice. I've been using a VTL Ultimate preamp for quite a while (along with a pair of their Deluxe 160 monoblocks) but have come down with a serious case of updateitis. I've ordered The Truth preamp and recently bought a pair of PrimaLuna Dialog Premium amps. Speakers are AudioPhysic Avanti III's and the front end is: digital – Roon on a NAS, Sonore's OpticalModule to a Rendu to a Shiit Yggy. Analog is a Dynavector DV20X2 on an Alphason HR-100S-MCS on a SME-10. My problem is what phono amp to buy. I've narrowed it down to one of the phono's that you both reviewed for TNT. The Black Ice F159 or the Lehmann Black Cube SE (probably the II).
My tastes in music vary widely and the system is reasonably revealing. My reading of your reviews is that either would be a great choice. I suppose I'm asking if you can put your heads together and make a recommendation (without prejudice!). Or at the least, if there's anything that either of you might add to your reviews that would help me end this most severe case of updateitis that I've ever had! Cheers,
Geoff - E-mail: geoffrey.binder (at) gmail.com

Hi Geoff,
Unfortunately, in my opinion, that approach is not a viable solution to determine the best phono for you. The reviews seem to have helped point you in the direction of these 2 units, and that is as much as you can reasonably expect the reviews to help you with.
The next step would be to compare the 2 units directly. And in your system and with your music. I strongly recommend level matched AB comparisons, and if you can swing the tests to be double blind, then all the better.

Re: Doge 8
Dear Roger,
Thank You for the insightful and in-depth answer!
I will write a short (hopefully) intro to try and create some references before the opinion of the preamp itself. (Skip 2 paragraphs to get the to the Doge impression).
Having a rather modest system few years ago (Pioneer A-A9 and PD D9) with KEF Q300 speakers and an old Rega P2 I tried my best to get some music from it became apparent that it was not happening.
Having heard a few fine sounding systems and reading Salvatore's philosophy of low power/efficient speakers I bought at that time the first Trends 10.1 and was amazed with what the little box could do. Unfortunately, at least in my experience, the old Rega could not deliver music to my taste and after hearing a Thorens 125 mk2 and loving it I decided to try the suspended approach. Having found an old LP12 for a good price and a Musical Fidelity M1LPS I finally started getting some emotions from ye old grooves.
After reading a lot on the Doge 8 and having faith in the unit (blind), once the funds allowed I ordered a Doge Clarity as this would a) Solve my lack of sources on the Trends b) get me a phono that would deliver more music and hopefully get me into higher planes of sound. And it did just that, I was really amazed with the change. Next were the speakers as the Q300 were fine for the price (second hand) but became the choking point and finding a second hand Proac Studio 140 Mk1 I never looked back, second huge leap in everything!
A year later I got a Coincident Dynamo mk1 ex demo in Slovenia to move up from my trusty Trends and this also brought a change for the better in all aspects. So I now apologize for writing a two paragraph genesis which was not causing a narcoleptic attack.
So, Doge 8, great unit, lovely build, solid looks in black in my opinion and a lot of versatility. The sound that first came to mind was transparent, flowing, airy and moving. It really made me listen to music more, with no fatigue (which I am prone to) Hearing only good stuff I decided it was time to try some tubes, I, as Yourself, found a Siemens NOS set of 12AT7 and this moved everything up a notch or three, depending on the aspect, more air, clarity, “legibility” as I like to call it, etc.
Next were phono tubes, I got a set of RCA NOS 12AX7 from a friend which woke up the phono section in a similar fashion. I also removed the shield caps in the phono and added Herbie's dampers with good effect gaining composure and tightening the sound a bit. One last thing that was done was a DIY the power cable which I doubted at first but at the end the differences were apparent, Doge gained some more of the good stuff, more air and flow, less constipation.
There is, I must say a small issue of noise that I get which varies to a degree depending on the time of day (neighbour's AC seems to have an effect on it, if I am not imagining) but still it seems to create more noise that just plugging the Coincident directly in the CD for example. Do You have the same issues and/or any ideas on solving it? (My thoughts are tubes and power).
I do hope that this email did not bore you to a great degree, and some interest might come of it!
Would love to hear Your take on the noise issue and any other experience, if any.
Looking forward to Your reply,
Best regards,

Dear Vuk,
Always good to read about other peoples experiences and the evolution of their systems. You will be glad to know that I was able to read all the way through without the onset of narcolepsy!
As for my opinion on the effects of AC power noise on an audio system, well, you asked for it! I had a 40 year career as a power engineer and I have extensive experience working with electronic equipment in an industrial environment. Let me start by saying that my comments are specifically directed at electrical noise issues and do not pertain to long-time variations in the electrical supply such as voltage sags. If your neighbor turning on a large compressor causes problems in your audio system that's not a noise problem, it's a power grid stability problem.
Power supplies in audio equipment are designed to do 2 things, 1) convert the AC line voltage to the required power specifications of the device , 2) filter noise. The conversion from AC to DC automatically blocks most of the noise to start with. Typically, the more "high-end" the component, the better the power supply is. It is quite common to see high-end components with massively over sized capacitors in them. Capacitor = filter. Typically, any noise that might possible get through the power supply and into the audio signal path would be extremely sporadic. Think of an event with a duration of a few milliseconds happening a couple of times a day. One experiences more disturbance to listening enjoyment than that from someone knocking at your door or the refrigerator turning on! Furthermore, music is a continuous flow, the only way a noise signal could become an issue would be if it was fairly continuous which again is highly improbable. Usually we don't even hear the fridge turning on because our brain automatically blocks it out because it's not music. Now, think about this; all of the "noise" produced by a tube - harmonics, micro-phonics, random noise inherent in tube operation. One could easily argue that the noise signal form a 300B drowns out the noise coming from the power supply. Yet I absolutely love 300B tubes, as do a vast number of audiophiles. Therefore, in my opinion, unless one's next door neighbor is a large industrial complex such as a car factory or a steel mill, it is highly unlikely that electrical noise would be an issue in sound quality. Yes, I have some audiophile friends who insist on doing their critical listening after 11 PM as they believe that the power grid is noisy during the day. For a typical, North American, residential power distribution grid, the noise contribution from all the private dwellings is like a drop in the ocean. Really, in my younger days I did the math on this. And industrial plants operate 24 hours a day!
In conclusion, electronic equipment is much more sensitive to noise on the signal line than noise on the power line and it is much more difficult to filter noise on the signal line than noise on the power line. Power line noise exists and can cause problems in audio equipment. However I believe that in North America at least, it is much less frequently the cause of audio system noise problems than generally believed.

Doge 8
Dear Roger,
after reading You review of the preamp "The Truth" I realized that Your system also includes a Doge 8 which I too have. Few days ago, after getting a new CD player (second hand Audio Note 2.1 mk1) and being underwhelmed by performance I decided to try and plug it directly into my power amp as it has a volume know (Coincident Dynamo mk1). The transformation was not subtle, and my and my friends conclusion was that the CD now performed with less congestion, frequency roll off-s, albeit a little lean on bass (but what was left of it was more coherent).
So my attention came to Your review and the preamp on the test and I wanted to ask how does the unit perform (still in the system?) and did You have any other conclusions along the way?
My other question is if You have any experience in tuning the Doge (which tubes, isolation, cables etc) and how did You manage to bypass the line stage and use just the phono section?
Thanks in advance for Your reply and thoughts,
Best regards,
My system: Coincident Dynamo mk1, Doge 8, vintage Linn LP12, Audio Note CD 2.1x mk1, Proac Studio 140 mk1 speakers.
Vuk - E-mail: vuk.miljus (at) gmail.com

RMcC
Dear Vuk,
Thanks for your email. I do still have the Doge 8 Clarity in my system however since the acquisition of The Truth line stage I typically use only the phono stage of the Doge unit. I am able to do this because Doge was nice enough to modify my Doge 8 Clarity at the factory before shipping it to me. They provided RCA sockets from the phono stage on the back plate. This allows me more versatility when reviewing equipment. Furthermore, the Doge MM phono stage is the best one I own so best use it!
I am still quite impressed by the Doge 8 Clarity and consider it to be at a performance level that would certainly be hard to beat at it's price point. That being said it is no match head to head with The Truth. As I stated in my review, The Truth combines the purity of a high end passive pre stage (except better), with the dynamics and vitality of an amplified pre stage. So I intend to continue bypassing the Doge 8 line stage and running my sources directly into The Truth except for when reviewing specific components which might require preamplification.
With respect to experimenting with various tubes etc. I can tell you that I have had interesting results with tube rolling which, in my opinion, is to be expected when swapping tubes in a high end preamp. My Doge 8 line stage is presently running with NOS Siemens tubes, circa 1970. This has drastically improved the performance vs. the original tubes. The phono stage is running on pre-war NOS Ei tubes which are also excellent.
I am presently using mostly unshielded DIY interconnects. These cables are doing a great job however a lot of care must be taken in the routing of the cables and the proximity of power cables otherwise hum pickup can become a problem. I intend to eventually build a shielded version of the Aircoil interconnect for use in the low level signal path between my MC step up transformer and my MM phono stage. Some may comment that adding a shield to the Aircoil design defeats the original objective of minimizing capacitance however I believe that there is still some headroom in this design for a bit more capacitance without affecting the frequency response. It is noteworthy that the excellent Dynavector interconnect that came with my DV507MK2 tonearm is a shielded cable.
I hope this is useful to you. It would be interesting to read your impressions of the Doge 8.

Dayton Audio BTR01 review
Hi, I've just read your article. I want to convert my Cds to a lossless format, and I'm curious to know why you chose Monkey Audio instead of Flac.
Thanks and best wishes from Italy,
Marcello - E-mail: prof.marcello (at) libero.it

DH
Hello, Marcello,
Thanks for asking. I'm afraid the reason for my choice of codec was not very compelling: when I started my "music server" project, and for several years thereafter, my computer was an old Gateway desktop that would run the Monkey's Audio front end but, oddly, not that for FLAC, even though the latter supposedly demands less processing power. By the time I bought a machine that would run FLAC, I'd already ripped all or nearly all my CDs, and not wishing to mix formats I've stuck with .ape ever since. Monkey's Audio does, or at least did, supposedly offer slightly better compression. That said, if I were starting from scratch today, I'd probably do what everyone else does and choose FLAC, just because it has better compatibility with hardware and other software.
Note that no "lossless" codec is going to crunch your files down to a size much smaller than 25%, more typically something around maybe 40-50% for CDs. For 78s, don't figure on doing better than something in the 70s. LPs usually do a little better than 78s, but not all that much.
I believe I've written this before, but just to emphasize: if you are going to rip your CDs, be sure you keep good backups, and note that RAID is *not* a backup solution. On a board I frequent, one computer professional wrote that in that discipline, the general thinking is if you don't have three copies of something, you don't really have it. Ripping and labeling files is not the world's most enjoyable pastime, to put things mildly, and you can take it from me that you do not want to go through that process more than once. I'd also suggest that you think hard about how you want to organize your files before you start. If your collection is all or mostly classical, you may want a different structure from what you'd choose for all or mostly jazz or pop or an equal mix of genres. If you plan to copy only CDs, you may well be able to take advantage of automated labeling software and databases that were developed or perfected only long after I started my own odyssey; if you want to include needledrops, however, you may want to take something like the much more laborious manual route that I have, as described in an article I wrote two or three years ago.
These are just a few thoughts to get you started. Again, thanks for writing, and all the best with your project.David Hoehl

Vintage turntable
David, My less-effective-than-it-was memory suggests that the STD 305 was by Strathearn rather than Strathclyde and I suggest you look under that name on vinyl engine.com for pdf of manual I believe there were M, S and D versions and I seem that recall that the deck (not sure which version) had a reputation for revolving backwards. Still, as I said, it was a long time ago and the old memory is not totally reliable. Good luck.
Charles - E-mail: charly.beagrie (at) talk21.com

DH
Hi, Charles,
You're remembering correctly that the STD 305 came in variants D, M, and S, with the D being the one that has a digital readout and 78 speed. These tables definitely are Strathclyde, however; I own one, and that's the name. The Strathearns were the stm4 and sma2; I've never seen either one "in the flesh," although I saw an advertisement for one or the other on a local classifieds website once. My curiosity aroused, I read about them a bit, and if what I've read is true, as you suggested, apparently they were said to run backwards sometimes. As far as I can tell, neither one had a 78 speed, and if this none too flattering article about the company's history is correct, their motors would not have been up to the challenge of 78 RPM playback. I hope that clears things up about two companies with confusingly similar names.
Thanks for writing!

Re: Yugoslav tubes
I spoke with Mr. tubes.rs, and here is his interesting story:

Yes indeed, EI tube factory was all Philips, and ECCs were Philips and everything was Philips, but...
Sometime in the 80s tube factories were closing all around the world but there was still a considerable demand. Telefunken could not produce enough, so they asked for some outside help. They approached EI Nis to stamp plates for ECC 83. A deal was signed where TLF will send raw material (nickel iron rolled sheet) EI will make plates and send them back to Germany. Deal was honored, everything OK. However, some surplus sheet was stamped for local use and they made batches of TLF ECC 83 (and maybe others) without authorization, using other quality components and reverse engineering. These tubes have grey plates (German sheet metal).
Later 'fake TLF' production has shining (silver, nickel) plates, this is Soviet sheet metal of inferior quality. Don't know if this applies for Philips based ECCs as well.

Referring back to your message, I would say the statement #2 is closest to what really happened. Given the promiscuity among tube mfrs in those days, I am not surprised any more.
So much about EI Nis. Now I have a question: suppose that The Fisher 100 (EL84 PP) falls into your lap, and you want to just use OPTs, what schematic would you use for that DIY project? I know, I know.. there are myriads of those on the net, any favorite?
To be more specific, your opinion on https://diyaudioprojects.com/Tubes/EL84-Mini-Block-Amps/ or any other favorite?

Dear Vojin,
Hi Vojin,
thanks very much for the research on the EI factory, great work. With regards to your question about a DIY design for an EL84 based amp, I have to say that I can't help you on that. My understanding of tube audio circuit design is limited to basic understanding of the various topologies (and of course what they sound like).

Acrylic platter on Rega P1 turntable
I use an acrylic platter on my Rega P1 turntable, what's your opinion on this?
Thanks,
Luca - E-mail: luca.c24 (at) alice.it

RMcC
Dear Luca,
Thank you for your email. I have deduced that you replaced the original platter with an acrylic one. A quick search discovered that the original platter on the RP-1 is made of phenolic resin. Unfortunately I have no definitive information on the differences between these two materials so I can't provide any comment on whether or not this is an improvement over the original. The only thought that I can offer on this change is that the RP-1 is an Entry-Level turntable and therefore may have some issues with driving the new platter if it's mass is significantly higher that the original one.
Best regards,
Roger McCuaig

Re: Yugoslav tubes
We are in deep water now.
Is this the place that sold you the tubes: http://www.tubes.rs/ecc83-ei-yugoslavia-smooth-plates-12ax7/ In the meantime I spoke with the owner of Korato. He should know as he had direct involvement with EI Nis, Manley, KT 90 etc... Long story... (KT 90 is based on PL519).
Anyway, he is adamant that ALL Ei tubes were Philips licences. All machinery and documentation was bought from Philips in the early 60s, probably on cheap as semiconductors were taking over. EI were churnig out vast quantities, mainly for their TV sets. They were not interested in audiophilia, ECCs were sold as 'service' (spare) tubes, very few went into their own products (e.g. PA amps and the like) They never made a tube based HiFi product.
Before I jump into conclusion, I have to check the statement on tubes.rs which reads:
EI Nis has also the same version in silver (“nickel”) plates and completely another version on Philips tooling machines, they are ribbed plates.
Can't reach the guy on the phone right now, will let you know his story.

Victure players
Hello An Italian friend of mine sent me one of your review (Victure clip sport player) and as mentioned in it the Doodcool player on Amazon site.
Knowing not much in these kind of machines (nor machines in general). I wrote him my generous wife offered me the Bose 700 headphones Bluetooth. Except she knows even less then me. I realized that the main users are the ones that already own very performant cell phone. This is not my case. My passion is music I listent to it everywhere, I have 2 old now i pod 160 go whom batteries begin to be worn out (ant it seem that they are not replaceable) too old any way for Bluetooth. So I look for an appropriate mp3 readers that could match with this superb headphones (noise reduction quite appreciated for the use of 2 or 3 subway hours a day.
I would use it very basicly start a mp3/cd and listen to it till the end. That is the old way using or the way olders use. This for not too expensive (no more then 250 euros but if less i would not cry).
So this Victure or the 16 go in this optic could be the one or do you see better options?
Thanks a lot
Luc - E-mail: lgahery (at) hotmail.com

The Sport Clip is the smaller and lighter of the two Victure players. It has mechanical buttons where the other model has a touch screen interface. Otherwise specs are more or less the same.
I listen to Flac on mine. SC cards are cheap enough now to keep some 'extra' music on a spare one but even with a 16 GB card I find that I have plenty to choose from.
All you do is connect the music player to a USB socket on your compute (a cable is supplied), and copy and paste the files to the player using Windows Explorer or similar.

78rpm turntables
Dear Mr Hoehl
I've read your very interesting articles about 78rpm turntables. I have a few 78s that I occasionally play on an 1950s suitcase turntable, but I was looking for a record player to play them on my hifi system. Being on a tight budget and given this would be an occasional experience, I wouldn't spend too much on the turntable. I was wondering if you have experience with Audio Technica turntables (there are currently 2 78rpm SL-1200 lookalikes in their lineup) and if you would rather recommend one of these over a Lenco L75 or even the Numark, both of which sell used for about the same price as a new Audio Technica.
Thank you
Kindest regards
Andrea - E-mai: holden75 (at) gmail.com

DH
Hello, Andrea,
I have no personal experience with the Audio Technica tables, but a longtime collector friend has one, an ATLP120-USB, which he describes as "a lower-end model (it cost somewhere around $300), which has variable speed but only around 33, 45 and 78." When I asked him about it, back around the time I was writing the series of articles, he said he'd been playing it for 5 years with no problems. I do have experience with one Numark model, as I outlined in one of the articles, and it wasn't good; the turntable became unusable after only two or three years. I'm therefore personally leery of Numark, but, on the other hand, I believe the manufacturer has fixed the design flaw that gave rise to my problem, something to do with elements on the control board overheating as I understand it. My advice about Numark, then, would be to proceed with caution but not necessarily to rule it out. Just be sure you've thoroughly researched that Numark tables no longer have inherent problems, or if you're looking at an older one that it was built after the company addressed them.
As to Lenco, if you can find one at a good price, many collectors swear by them, and by no means just for 78s. Certainly a Lenco table in good condition will have ample flexibility to handle whatever "78" you decide to throw at it, and the line's adherents consider them top notch LP players as well. The problem there is that they have developed a "following" and no longer are the inexpensive solution they once were; moreover, the Lenco fans tend to view an "as found" turntable as just a starting point, needing lots of tweaks and modifications--new plinths, rebuilt arms, and on and on--to become what they consider a world beater. If you don't have time, patience, and money to put into such rebuilding, you may want to stick with something newer, even if it lacks the full potential of an older component. For more (much more!) information about Lenco, I'd suggest you browse the Lenco Heaven website, which has an abundance of information about these old warhorses and their care and feeding. Good luck with your search!

Yugoslav tubes
[Triode Lab 2A3 EVO Front view] Dear Sir,
I read with interest your review of Triode Lab 2A3-EVO in TNT-Audio. May I point to slight inaccuracy in the text. You claim 'I was quite tempted to try my NOS Ei 12AX7 tubes that were made in pre-war Yugoslavia on Telefunken machinery'.
To my best knowledge the EI Nis factory, who was the only tube producer in Yugo, used Philips licences and equipment. Majority of tubes were made for TV sets, with P heating. They did make ECCs (that is 12A,,, for you) for radio/audio, EL84, EL34, They did not make KT88, tried their own KT90 instead (nothing special). ECCs from Nis are highly regarded among audiophiles, yes they are very good, comparable to Mullard (same construction).
I am positive about Philips connection, they may have bought some machinery from Telefunken later, but I doubt it.
Best regards from Belgrade,

Dear Vojin,
Thanks very much for your email. I did some research on the internet and found the following:

  1. The company that sold me the tubes indicates on their web site that they were built identical to the Telefunken tube.
  2. On an audio blog I found an owner who says that they were made possibly on Philips tooling but were a copy of the Telefunken design.
  3. A NOS tube seller in Ankara writes that they were made with the Telefunken design and tooling.
  4. I have found several other blogs and web sites that indicate Telefunken tooling was used.
Of course it is entirely possible that someone mistakenly wrote that these tubes were made on Telefunken tooling and it got picked up and spread all over the Internet. Let's hope that some TNT reader can provide a definitive answer to this question.

Re: Cambridge CXC CD transport
Hi Chris,
I solved the problem. Yesterday, I went to one of the most amazing hi-fi stores I have ever seen - crammed with fantastically presented gear (Nautilus2 in Rzeszow, https://nautilus2.pl if you're ever in this part of the world). They set up my X-DAC with a CXC and it worked! The HDCD light came on immediately, so I don't know what those guys at Cambridge Audio are smoking. They are simply wrong. Sorry to bore you with my ongoing story but at least now I can enjoy the CXC to the full.

Victure Clip Sport player
Hello,
An Italian friend of mine sent me one of your reviews (Victure clip sport) and as mentioned in it the Dodocool on Amazon site. Knowing not much of this kind of machines (nor machines in general) I wrote him my generous wife offered me the Bose 700 headphones Bluetooth. Except she knows even less then me. I realised that the main users are the ones that already own very performant cell phones. This is not my case. My passion is music, I listen to it everywhere, I have 2 old now ipod 160 go whom batteries begin to be worn out (ant it seem that they are not replaceable), too old any way for Bluetooth. So I look for an appropriate mp3 reader that could match with this superb headphones (noise reduction quite appreciated for the use of 2 or 3 subway hours a day).
I would use it very basicly start a mp3/cd and listen it till the end. That is the old way using or the way olders use. This for not too expensive (no more then 250 euros but if less I would not cry. So this Victure or the 16 go in this optic could be the one or do you see better options?
Thanks a lot,
Luc - E-mail: lgahery (at) hotmail.com

Hi Luc,
Both the two Victure MP3 players on Amazon are very good, and even better given their price. What I am finding is that Bluetooth connection seems to be a bit hit and miss on all this modern gear. The Victures that I have here will connect to one pair of Dodocool Bluetooth headphones, but not another Dodocool model. So what you need to do is find out if your Bose headphones will work with the Victure players (you can ask on Amazon). The supplier seems very keen to help with such information).
My view of buying this sort of gear is that it will eventually break no matter how much that we pay for it. So buying cheap is sensible, and honestly doesn't have to mean low quality sound. For listening on the go, there will always be some background noise, even with noise-cancelling headphones, so spending hundreds on these items is (IMHO) overkill.
Let me know if you need any more help.

Nick Whetstone

Cambridge CXC CD transport
Chris,
I just read your review of this unit. Can you please let me know if it transfers all the CD data to the DAC. I have a wonderful Musical Fidelity X-Dac, which can process HDCD format CDs. I have been unable to ascertain whether the CXC will transfer the necessary information. Some reports say yes, some say no. Would appreciate your advice.
Regards,

Hi Conor,
The CXC is a CD only player. It does Not read SACD's. I have found it to be excellent and (although this may sound stupid) as good at reading a CD as my pc drive. Keep in mind a pc CD drive has the ability to read at up to 54X speed unlike any normal CD player I have heard of. This point was the reason I moved from my Jolida player. Even using the digital out on the Jolida the Philips drive was not getting all the information from a CD.
Hope this helps,
Chris Templer

DAC comparison
Hello Nick, Happy New Year.
I have been following your writing for awhile now and feel it very accurate from my experiences and refreshing free from all the advertising end of it.
I have a good question, how do you compare the Mhdt Pogota dac to the new Jolida Dac? They both have tubes to upgrade as well as coupling capacitor upgrades.
Please give me your opinion on how they stack up.
Best regards,
Paul - E-mail: audioman58 (at) gmail.com

Hi Paul,
Thanks for your kind comments. As I have not heard the Jolida DAC I can't make any comparisons.

Audio Note R Zero II
Hi Graeme,
Thanks for the review on the Audio Note R Zero II phono. Have you listened to a Simaudio Moon 310LP phono? I have one and just love it, running into a MF NVista 800 and a pair of ATC SCM 11's from an old LP12. I've always enjoyed tubes and a local store is bringing in a R Zero phono. Trouble is it's so hard to demo these things. Their unit might take months to break in. Their amps and speakers won't be the same. The room is different etc. I noticed that you gave the Graham Slee it's due in the review and just wondered if you'd ever listened to any of the phono stages by Simaudio Moon?
Cheers,
Stephen - E-mail: goodridge.s (at) shaw.ca

Hi Stephen,
Thanks for taking the time to write - it's nice to know people appreciate what we do!
I've never listened to any of the Moon range I'm afraid (or certainly not in any familiar circumstances) so I can't compare the AN directly. The AN and GSP units are both highly enjoyable and I could happily live with either. The GSP is more precise sounding whereas the AN is disarmingly musical. My personal CEC PH53 sits somewhere between the two and as such is a great compromise unit.
Maybe taking your deck and your SIM unit to your dealers would be of benefit once their AN has a few hours on it? You'll at minimum be able to see the differences even if it won't be exactly the same as at home. From what I've read about the 310LP you're in for a surprise - whether it be a good one or a bad one only you can decide.
Kind regards,
Graeme Budd
