| Are future improvements in Amp/PreAmps slowing to a crawl? kosst,Do you think that after decades of work trying to analyze the tiny events that lead up to the production of harmonics that I'm going to say "Oh I know - I'll just use negative feedback - why didn't I think of this before?"Ok here is a fact:I... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst, The source of distortion in a gain device is related to deviations in it's transconductance. Deviations in transconductance are, at the very least, the byproducts of capacitance, resistance, and inductance within the transistor itself. The... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst,Can you explain to me how an amplifier can produce energy at 2khz when all it has to work with is the pure 1khz tone applied at the input?If you don't think it is using a modified version of the input to do this then if you stop the 1khz i... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? Roger is claiming circuits alter play speed AND he claims that's the source of distortion. That's pure BS. This is exactly what I'm claiming. | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst, Harmonic distortion is caused by nonlinearity in the gain devices. Period. I agree 100% - we know it is caused by nonlinearity I'm not disputing that.I am saying that I know the means by which harmonic distortion is actually generated by ... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst,Apparently you've been at this gig for years judging by the guy who offered to take a listen to your gear who wasn't overly impressed the last time he heard it.Its true - of course that was ten years ago. A lot of progress including a few ... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? @stevecham Zero "velocity distortion" is an oxymoron. Just as there is no net movement of air molecules in the propogation of soundwaves, so too there is no net movement of electrons in the propogation of electrical signals in audio circuits.Ver... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? You can't show me a circuit that does what you claim. You can't because it doesn't exist. If it existed you'd have patented it. Patience grasshopper - and all will be revealed. | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst,I'm not accusing you of being the measurements freak. I'm sorry if you got that impression. I'm trying to show the difference between an amp that measures zero compared to an amp that IS zero.One sounds awful and one sounds incredible. Can... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? You do realize I know the circuit you are listening to.Really good designers understand that carefully chose distortion is much better than no distortion.Not true. If that's what they think then they are not a really good designer.Something else... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? Sorry my bad. So I guess that the raw circuit is fine by itself. Its just that if you want to make the sound even richer and fuller than the original recording - then you add the extra distortion. This also gives you the added bonus of listening t... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst Everybody knows you can manipulate a signal to sound like all kinds of things Well that is certainly true especially if you have a way of adding your own flavor of distortion....even those things you claim your gear does. Here is where t... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst,He doesn't know what a 100% distortion-free amp sounds like. He's never heard one.I thought that was the whole purpose of his visit.Unless he has calibrated microphones for ears, oscilloscopes for eyes, and a distortion analyzer for a brai... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst Practically everybody who builds one applies some positive phase second order distortion through the NFB loop balance to warm the sound up and open up the stage. There is your red flag. | |
| Are future improvements in Amp/PreAmps slowing to a crawl? kosst,Don't you think it would have been wise to wait until the gentlemen from PA was here to verify if this is in fact for real or a hoax? |
