I would say WHY ON EARTH DID YOU SELL THAT AMP..

Anyhow, I have one of those amps, and I would never sell it, over using the amp inside of a receiver.. the marantz is just SOO clean, and powers the speakers so effortlessly..


But, sense what is done is done, I would say don’t sweat it, calibrate your system, and
A) don’t worry about it enjoy what you have now..
B) buy another you can get them off of ebay for about 600$...
