A Brief History of Amp DBTs

"This does not suggest that amplifiers are perfect and they will never
be found to sound different." The sound of an amplifier is directly
proportional to the extent of the differences found between them
and how far each differs from theoretical perfection.
Actually, there is no such global proportionality. There is a point where
audible differences become small enough that they are not discerned by the
human ear, and are simply not noticed no matter how ideal the circumstances.
For instance. Lets take two modern, solid-state amplifiers. Let us
stipulate that both are fairly equal in power output, distortion and
frequency response.
Which would seem to falsify the following:
But, let's say that one of the amps has an average
run-of-the-mill power supply while the other has a huge supply with
separate and very large power transformers and separate
supplies for each channel capable of sourcing many more amps of
current to the second amp than is available to the first.
As long as the power supply of an amplifier is adequate to maintain internal
voltages within the realm of sufficiency, any excess capability has no
effect on either measured performance or sound quality.
It's just excess weight and expense.
Now. lets operate both amps near their limits with difficult loads.
The above statement continues to hold: As long as the power supply of an
amplifier is adequate to maintain internal voltages within the realm of
sufficiency, any excess capability has no effect on either measured
performance or sound quality.
I'll guarantee you that even though they might measure almost identically
in the
above mentioned parameters, under normal circumstances, in these
circumstances, the amp with the largest supply is going to sound better.
Your guarantee is worthless because it violates both actual experience and
the principles of physics.
