I had a problem with proceed AVP. Braqnd new out of the box. It had 60 cycle hum and I had the dealer com eto the house with another AVP and side by side we hooked them up and sure enough it was the first AVP. MAdrigal took it back and acknowledged htat is existed and mailed me another AVP. ANyway, if your item is new then send it in. If not, maybe still possible to warrenty it but first try using ungrounded connectors (convert three prong to two prong) on all units in rack EXCEPT one unit...anyone yoo choose. You may be getting a ground loop. Keith
last try :) buzz in system
Buzz in system with Proceed I have a Proceed DAP CDD combo running through a Denon AVR 3300 for a pre amp. If I put the cd player on pause and turn the Volume up to high listening levels, there is a buzz. I thought it might be the cables (Apature silver) so I used az different set. Same thing. The amp I am using is a Mac MC 162. I thought it might be the Denon creating the buzz so I ran the Interconnects right out of the Proceed DAP right into the amp (you can do this because the DAP hhas a volume controll on it). THE BUZZ WAS LOUDER!! Took the DAP into the shop and they could not hear a thing. Any ideas? Gary
