I don’t know if that assumption is correct or not. I can’t honestly say if the improvements I had are from the amp or the processor sending the signal to the amp. I’m guessing a little bit of both. I think once you get to a certain point in current supply, adding more does you no good. However, the quality of that power will definitely make a difference. As will how the source signal is sent to the amp.

At any rate, I most definately notices a difference. Enough to where a blindfold wasn't required.
