Concerning transformer use. Interesting, wonderful but brutally simple transformer designs, in many vintage products do create a nice, slightly "warm" sonic color but there are modern products which can do the same sound trick but without the high expense and use of rare parts. First be aware of the +24dbm maximum operating level (transformers or sound state) used in real pro signal level designs do not mate perfectly with "semi pro" equipment designed to operate at at +14dbm 10k load levels....Read Full ArticleRead Full Article
Q) Would like to hear your best price on the American R331 microphone you have listed.
A) Actually, I don't have any left in stock now but had many previously here. Be aware now so many better, correct, lower noise, working ribbon microphones for less money now exist. I would not recommend the R331 now for quality of performance, although I do have some original boxes for vintage collectors who indeed pay a serious premium for a rare item. Truth is they were quite low in output and very susceptible to even 120VAC noise pickup. They look great but...Read Full Article
We get many letters and phone calls asking about certain high dollar audiophile gear, which all basically boil down to - does this unit do what they claim it does?
Many manufacturers make remarkable claims of amazing fidelity. Are these electronic designs capable of revealing or creating more lifelike imaging or depth of detail when amplifying pre-recorded music? Does the use of super special capacitors, wiring, and connectors by esoteric manufacturers create euphonic nirvana? Listeners are so cleverly convinced of the quality of sound reproduced by a fancy built and expensive device, they will defend their choices quite adamantly. The problem is they are not really making a fair comparison of all existing technology at any price point low or high....Read Full Article
A Letter from the Owner Vince Naeve
People have been commenting about some chatter being posted on the web. A long time friend and customer has recently made me aware of this. As usual, in this world of sound bytes and quick words taken out of context, I feel people have read me incorrectly, or more over, have not understood a deeper realization about the recording or Hi-Fi industry and the equipment they transact...Read Full Article
Q) I have a pair of ads 810 series 2 a tweeter went out and I got a replacement. Not the stock 3/4 inch softdome though. Do you have any of those available? And I have a curiosity mabe you wouldnt mind answering this for me.(I know its personal preference) If you had only two choices between a/d/s 810 & Polk audio monitor 10 which would you pick? Kinda like Mustang vs Camaro, apples against oranges.
A) I've owned ADS which I prefer (if they are modified), and bought and sold Polk many times. These typically are just OK speakers. Their design and use of "passive bass" radiator is a cheap way out and not a properly designed speaker....Read Full Article
Q) I am looking for the best set of vintage speakers by either KLH or AR to couple with a Macintosh receiver ca 1970s. I have some 5s which I like, but I want to add another pair. Would you recommend KLH 6s or 20s or which model for the best sound possible? Also how do you compare AR with KLH.
A) AR and KLH are very similar in many ways. Later version AR possibly have better tweeters. The real old speakers either have limited performance tweeters which must be replaced or without a doubt an updated crossover is needed ...Read Full Article

Q) I am interested in the B2 Pro. I want to create a U87 clone with my original K87 capsule. Can I get a good U87 clone with your mod and changing the stock capsule to my K87 capsule?
A) Sorry, I don't know ...it won't be the same, can't be ! In fact some china capsules are actually better ! The real issue is the bias volts on the capsule , internal "meg ohm" load & high frequency trim capacitor as well as gain circuit equalization will never make it the same ! It might sound acceptable. Simply put an original B2 pro is a very different, super wide range, high dynamic range capsule, that is better than most. It's internal preamp circuits are designed for that. I have changed over to apex , similar capsule (the best for the price -case closed!) and it does sound quite similar but a little softer ... to use a layman's description. Want a U87? Get a CAD 8000 with a little mod. It has transformers (B2 does not) and sounds very much the same as a new fresh U87, for $300. Why modify ? Great mica are available for $150 to $300 USD. that beat anything you can build or modify. Thanks for your inquiry, contact me if you interested further....Read Full Article
