I love Monty Python, and know of the "Nudge Nudge" sketch, but am unsure of how that fits....
Ultra high resolution
Hi folks, I suppose this is a question none could answer appropriately. How come that some (there are to my knowledge only two of them) amplifier brands are building such ultra high resolution solid state amplifiers without having a treble that sounds shrill or piercing or artificial? It is of course proprietary info if you ask those manufacturers.
Is it because of very tight selection of matched transistors? Is it because lack of global but high level of local feedback? Is it because of the use of very expensive military grade parts? Is it because of the power supply? Is it because of the application of special circuit design? Is it because all of the above?

Joey: It should be the "World's Most Deadly Joke" sketch. Heheh Nah - the most deadly "dead" joke sketch is this one. ...and now back to regular programming! (Sorry Chris I just found your initial question that does not even mention which amps you refer to ... a bit too vague - "know what I mean, Ay, Ay" ) |
Joey- Don't worry, It really doesn't. Actually: Some mil-spec suppliers(Vishay, Caddock, etc) are used extensively in the best audio gear for their low noise resistors (http://www.ecircuitcenter.com/Circuits/Noise/Noise_Analysis/res_noise.htm), BUT: the key to resolution without glare is passives in the signal path that are designed for audio circuitry(IE: caps by MIT, RELcap, RTI, V-cap, Jensen)(http://www.reliablecapacitors.com/pickcap.htm), and well designed power supplies. The less that's in the circuit/signal path(input to output), the better. And YES- point to point wiring(which is rare in SS designs)instead of PCB traces. The better companies have improved upon PCBs to great degree, and again that takes research, time and money. (http://www.ultracad.com/articles/pcbtemp.pdf) There are many other factors involved, and they all add up to a more transparent amp, but(of course)- those don't exist(AY?). |
Thank you for clarification Rodman. So when the passive parts in the signal path are essential for getting the highest level of resolution, why do even the big boys in the business, like Krell and Mark Levinson are including cheap parts in the signal path? They know this will compromise the final sound significantly. Otoh some manufacturers say: Nah, it's not the quality of the passive parts that counts but the circuit design and the appropriate implementation of the parts. What is your opinion? Chris |
