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?

not a bad question at all, I think.
Seems with one amp I have which I think fits the bill to a degree, lack of internal wiring i.e. very short distance between things, only 1 board with input/output and power jacks mounted directly on board, point to point soldering, a real mother of a transformer and output caps, minimal protection circuits, no fuses.
The opposite you talk about, lack of detailed resolved etc. harsh sound, I have heard from units with lots of boards/devises/controls/wire/ inside.
I love Monty Python, and know of the "Nudge Nudge" sketch, but am unsure of how that fits....
Xie: Can you tell us which power amplifier you have in mind?

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?).
