| 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... | |
| Holographic imaging 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. | |
| Holographic imaging 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... | |
| Holographic imaging 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... | |
| Holographic imaging 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... | |
| Holographic imaging Roger,The reason you cant 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 ... | |
| Holographic imaging 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 ... | |
| Holographic imaging Roger, the term for the time it takes a signal to pass through an amplifier is called Propagation Delay. It is usually a constant at all frequencies within the pass band of the amplifier circuit. But- has nothing to do with Doppler Effect.I notice... | |
| Highly efficient speakers to pair with my SET amp I can second the Decware choice, along with a recommendation to look at Tonian Labs. The Ref3A stuff is excellent also, maybe not as efficient as ideal for an SET, but an easy load, and that's important too. | |
| Holographic imaging Roger, I have many times had test tones being played through loudspeakers with microphones and frequency counters in use- never in the years of working in and out of the recording studio have I ever observed a connection between gain and pitch as ... | |
| Highly efficient speakers to pair with my SET amp Betsy- if you are running an SET with 18 watts, you need more efficiency than 92 db to really hear what the amp is all about. One inexpensive way to get that is the ZU Druid- but if you look into them, make sure they are a new pair or a set that h... |
