Good to know. So it's more about the sound signature of which amp you use than how much power it has. I knew this, of course, in terms of synergy, but just thought there was something more intricate about it all. On the other hand, if all amps do is amplify the signal as you say, wouldn't that mean all amps sound the same? This is clearly not the case. I wonder which amps are the most neutral aside from HeadAmp, which I always hear about.
All ideal amps do is amplify the signal, and yes, all ideal amps should sound the same.... in the land of theory.
