Are you sure that it is the amp and not just cables crossing over each other? Try isolating cables (only hook up one source, 2 speakers) and try it. Could it be a ground loop? Are you using a line conditioner? Final thought, can you turn the gain down on the amp?
Shield Amp from preamp? suggestions?
Recently got a Classe Cav-301...Placed it on the rack below my Integra Research Pre...I know they are affecting each other because of a slight buzz, the music and HT sounds slightly thin...and even on the digital volume display on my Integra I can see it sometimes "jitter"....When I first tested the amp I had it on the floor and it sounded awsome, but in the rack I hear the slight loss of quality..even in the Classe manual it says to keep the amp a few feet away from preamps, turntables etc. .Now of course I could move the amp, however this involves major reconstruction, new cables , power cords etc. Is there a simple way to shield the amp from the preamp like placing some type of shield under the preamp?
