Well for a while now I have been looking for an amp to augment my avr. I found one A Carver a500x. Bass improved mainly, but I think the highs stayed just about the same and for the mid it is a little louder not much. I just notice certain things I have not noticed there before. Got a good price for it I believe. Love the look, for some reason I like amps with meters. I have a few questions. Is it ok to turn off the amp with my adcom ace 515 power conditioner? Were should I adjust the the inputs on the amp itself? This amp has adjustments, right now I have them all the way up, i haven't noticed any problems with having it this way.
