Re: Serge/technosaurus etc --- operating voltage??

Sorry guys but I just gotta jump in here....
I'm no EE but the term 'wide tolerance' to me means 'large potential variance
from design spec'.
'Dynamic range' means 'large ratio of sound power between noise floor and
largest clean signal system can make' - usually expressed in dB.
A dynamic range of 100 dB is state of the art ... 90 is damn good ... 120 is
about all anyone could ever want or use.
What all this has to do with the voltage difference between power supply rails
is beyond me .... if this were really true, why stop at +/-20v (40v difference)
? You could easily go to 60v, 120v.... going to a 200v difference would be a
little more hazardous but I don't think much of a design challenge.
Are we talking about dynamic range of VCA's?? Then that comes down to the
quality of the gain cell ... usually just a question of the design trade-offs
with different amplifier types, quality of the semiconductors, etc.... going
with a good manufacturer, and their top of the line components, and then
individually testing each one to get the best of the best.
So, what are we talking about here?
