    AMV 20 making screeching noise

    I recently purchased a demo model Anthem AVM 20 and hooked it up to my system. When it plays for about an hour it starts making a slight screeching noise through the speakers. I know itís not the amp, Citation 7.1s. I hooked up a NAD L40 to the amp and it didnít make the same noise. I changed out the speaker cables too, no luck. I knew that was probably not the cause but Iím trying to rule everything out. I made sure none of the cables or interconnects are touching power cords so Iím not getting cross talk. I wouldnít think I got a bum unit but I guess itís possible. The only other thing I can think of is the building is really old and the outlet could be bad. Ok at this point Iím shooting in the dark. Help please.

    It's not the old outlet or house wiring that's causing your problems.
