2008 RMAF – – – all things analog.
I'll be there on the main floor in the Evergreen Ballroom, like last year. We are showing with Tri-Planar. We finally have a remote for the MP-1 too... Looking forward to seeing so many friends again!To anyone who may not know: the RMAF is the mos...

Tbg, some more things to point out. I've been careful not to say anything about how any of these products sound. I have only offered personal experience on what causes imaging. As far as the H-Cat goes, I'm only concerned with the explanation, not... 
SS or Tube Preamps with Dual-Balanced outputs
We've made balanced line preamps longer than anyone else. They can be optioned ($75) with dual outputs. I'll leave it to others as to what they sound like. Remote is available now for the MP-1.

Roger, please don't argue about the speed of sound OK? If you have heat, air conditioning, humidity control or lack of it, weather, what not- the speed of sound will change. You cannot ascribe that as a constant; it is constantly changing.Phase re... 
reserve vta solves issue on zyx, triplaner
Audiotomb, I agree. Funny how the ZYX cartridge behaves differently with different preamps, even when they are loaded the same. 
XLR Pin Vocabulary
One more note: Industry standard is pin 1 is ground, pin 2 is non-inverting (+) and pin 3 is inverting (-). Some manufacturers do not recognize the standard (we've even seen some using pin 3 as ground) but usually the only significance is that the...

The speed of sound in air is always varies depending on air pressure, elevation, temperature and humidity. 
reserve vta solves issue on zyx, triplaner
Hi Tom, Look into cartridge loading too. That can take out a lot of excess high frequency energy without loosing speed or detail (in fact increasing it).My ZYX is very relaxed in the Triplanar, and if anything the rear of the arm is slightly higher.

Tbg just to clarify some points, you are right, I'm not a fan of the THD spec. I feel that it does not matter how much distortion an amp or preamp makes **so long as those distortions are not found objectionable to the human ear**. By the same tok...

Roger, obviously you have spent no time with these musical instrument tuners. I have. They are so sensitive that they can show variation in pitch that is really hard to hear. The one I have is a rack mount unit and can show a deviation in pitch of...

Roger, you don't seem interested in answering my questions. Its been a while since I first posted them and you have made a number of posts in the meantime. So: I don't think you have any intention and that is borne out by your actions.You have con...

Roger,The reason you can’t see it with a THD analyzer is because it is way too subtle to show up. If somehow you alter the gain/velocity by a factor of 2:1 double the velocity! Then your 1khz signal will shift up to 2khz. A full octave away! That ...

Roger, 1/100th of a db? Really? So if the change in pitch cannot be detected by **musical instrument** tuning devices (which are quite sensitive, much more so that any frequency counter I've seen), it follows that it cannot also be heard by the hu... 
Holographic imaging
Roger,What happens in-between is not monitored - it is assumed.This is not true; this is in fact what Propagation Delay **is**. Any opamp designer and any amplifier designer worth his salt will be quite concerned about that number!So- its only whe... 
Holographic imaging
Alright Roger, how do you square:Yes I am familiar with Propagation Delay and all the classic textbook terms that pertain to amplifiers.None of which was helpful in troubleshooting the real issues facing a relatively simple task of making a small ...
