May 03, 2012	AUDIO RESEARCH-WHERE ARE THEY GOING I've known Kalvin Dahl for over 30 years. And Warren Gehl, Doug Wright... they are part of the core group of audiophiles that I hung with for literally decades and they are good people. I've known other people there for 20-25 years and I have a gr...
May 02, 2012	Surface noise Davide256, you missed one- design of the phono section can affect ticks and pops quite a lot.Bdunn, the first thing to do is to determine the value that you need. There are several ways to do that, you could get a stereo potentiometer, wire it as ...
May 02, 2012	I think my speakers are killing my amps. The VMPS is not particularly capacitive. Ribbons in general tend to have a fairly resistive quality so other than impedance they tend to be easy loads.
May 02, 2012	Preamp for Atma-sphere s30 Thanks Marty. We can update those older S-30s so we can get them to sound just like the current version. If we do that the warranty reactivates.
May 01, 2012	Surface noise Grados don't seem to like excessive tracking forces. I would not go above 1.7 grams.As per loading. There is a lot of discussion about loading MC cartridges (most of it bogus- loading MC cartridges is all about energy at RF frequencies rather than...
May 01, 2012	Digital microscope recommendations Now if only all the cutter heads used the same cutting angle we would be all set (they don't).
May 01, 2012	Wilson Sasha vs. older Watt Puppies The older Watts did indeed tend to have a brightness unless you were careful about your amplification. They worked much better with tubes in that regard than solid state, due to the way the resonance in the tweeter was controlled.The Sasha however...
May 01, 2012	James Burgess Hmm. I have a pair of amplifiers that I was told were made by James Burgess. They started life as Wurlitzer organ amps, but got modified to use 45s as SETs. The mod was done a long time ago- all of the wiring inside is done with cloth covered wire...
May 01, 2012	I think my speakers are killing my amps. Sounds like a protection relay. It may be that a device overheated and failed- thus the protection relay kicked in to prevent the amp from destroying the speaker.Either way it sounds like service is indicated. I would weigh the cost of repair agai...
Apr 30, 2012	Tube Preamp Paired with Tube Phono Stage? If you can get an all-tube recording as well as playback, then its even better :)
Apr 30, 2012	ProAc Response 2.5 transparent? The 2.5 is also very tube friendly!
Apr 27, 2012	Surface noise Have you done anything to load the cartridge? Grados seem to like about 8000-12,000 ohms.
Apr 27, 2012	Amp design logic Depends- does it have mayonnaise?
Apr 27, 2012	Tubes vs Solid State Bifwynne, I would certainly give the ZEROs a try and see how that works out. If you are using the 8 ohm tap, at the 70-200Hz region the power tubes are loaded at half of what is expected for them. IOW, the output transformer live up to its name- i...
Apr 26, 2012	Tubes vs Solid State There has been the question of why there is 4 ohms. The answer is that it makes it easier to make power with transistor amps.But making power is not by any stretch the same as making the best sound for a given amp. You can look at the specs of any...
