| Tube amps known to have a low damping factor? In tube amps the loop negative feedback is a big factor in the resulting damping factor. For example an OTL can be built with a damping factor of 50:1 if you have enough feedback. IMO such a large amount of feedback does nothing to improve the res... | |
| Is the most efficient speaker the best speaker? Unsound, you've asked a lot of questions and it may take a bit to answer them all. I think first it needs to be understood that human hearing/perceptual rules are understood much better today than they were 20, 30 and 40 years ago. I may have sugg... | |
| Is the most efficient speaker the best speaker? Y'know, you probably *could* do it that way... lol :) | |
| Is the most efficient speaker the best speaker? The best is whatever you prefer. There is no intellectual way to establish actual factual superiority without measurements and these forums generally decline that pathway when it is presented. This is an emotional experience that cannot be assesse... | |
| Oh how I wish Class D amps ... Mike, If you have a large room that may be true. But if your room is average size (17' x 25' or thereabouts) then I would not be so certain. FWIW, the live transmissions over FM have to be compressed to fit the dynamic range of the medium. I share... | |
| Is preamp remote volume a deal breaker for you? Dracule1, we investigated relay-operated volume controls and spent a lot of money in the process. They are quite good but a good quality rotary switch sounds better...Al, one *would* think that the shorter the cable the better, but even in the cas... | |
| What do you think of this preamp design? Kirkus, if that's a servo, as long as it is handled properly I would expect it to work fine. The schematic really did not offer timing data, and there should be some integration at the output of the opamp else the servo will not work correctly. We... | |
| mp3 based motor drive? If you have an audio generator you can do it that way too. The real issue is that the generated frequency has to be very stable! The best way I have heard of is to use a high frequency crystal-controlled oscillator where the crystal is heated in a... | |
| Is preamp remote volume a deal breaker for you? Hi Al, If you put a 600 ohm resistance across a cable, which has capacitive, inductive and resistive aspects, the outcome is that the 600 ohm resistance becomes the primary aspect of what you are driving. The other things (which normally affect a ... | |
| What do you think of this preamp design? Dracule1, you don't need RCA outputs on a preamp. What you need is XLR inputs on an amp. There is a way to do that such that both phases of the signal can be processed by the amp, without using a transformer and without changing the character of t... | |
| Is phase control switch a deal breaker for you? Viridian, I can't speak for all preamps but on our preamps the phase switch is very simple, as our preamps are internally balanced. So to do the phase reversal requires no circuitry other than the switch itself.I have found that the switch does no... | |
| What do you think of this preamp design? We are trying to have it ready for RMAF... at any rate, like the MP-1, the remote for the MP-3 will be retrofit to any earlier MP-3. | |
| Is preamp remote volume a deal breaker for you? The standard for balanced line is the output of the device driving the cable should be able to drive 600 ohms or less (in the case of microphones) without degradation (this calls for a fairly low output impedance BTW). If the cable is terminated a... | |
| Is preamp remote volume a deal breaker for you? My preamp is 3 feet from my listening chair. It can run really long cables (I have 30 feet) without any problem so even though I have a remote in the preamp (it uses a custom built switch for the volume control, which is driven by a motor) I never... | |
| SS amps with little or NO feedback Kijanki, if it is a true balanced differential design the main harmonic created will the the 3rd, not the 2nd. All the even orders should cancel. This is true of tube or transistor designs. |
