"No its NOT possible, and YOU don't have a clue !!!!! You are clueless."
Maybe you could define what you would consider to be the properties of an "ideal" power supply? My definition would be one that gives a constant voltage, independent of the loading by the amplifier.
In practice, of course, one can never precisely attain the ideal goal of an exactly constant voltage. But one can get essentially arbitrarily close to it. And certainly, close enough for the rather undemanding purposes of a home stereo system.
Do you disagree with this ideal goal of a constant voltage? If so, you are then arguing that you want the power supply voltage to be modulated by the loading of the amplifier. Or by the oscillatory mains voltage.
Now, as I and others have said before, it may perhaps be that you actually *like* the sound effects that result from having the power supply modulated by the amplifier load or by the mains. That is your prerogative. All kinds of sound effects can be achieved by making the power supply voltage vary, either in time with the music or independently of it.
But if you want to make a sound-effects box, there are better and more controlled ways to achieve it than by means of a floppy or sagging or rippling power supply.

Chris,
You are beyond me having a conversation with in audio, at anything over a mid-fidelity level.
Go back to your text book approach, and live happy ever after !!

I wasn't aware that you had any aspirations to listen to audio above a mid-fidelity level.

The moderators feel that allowing this thread to continue, even though it may hold useful information, will wind up creating more trouble than it solves, and thereby detract from the purpose of this forum.This is not the appropriate venue for discussion of this matter, and we ask that those with an interest in the subject, take it elsewhere (e.g. private e-mail).
No further follow-ups will be considered.
Thank you for your support of the Asylum.
