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

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

When you state that you hear a buzz when you turn the volume up, how up are you talking? If you don't hear it when the CD is on (not on pause and not playing) and at a reasonable volume level, then you shouldn't be concerned. If you do, try using shielding interconnects btwn the CD player - preamp and preamp-power amp. Is this hum nonexistent with other components?

the buzz can be heard when the music gets soft at a listing level about 90- db or better. it only resonates when I am listening to a CD. If I have a movie going through the Denon, I can blow the walls off and on quiet parts, no buzz. It has to be comming from the dap. Also the interconnects ai use are apature silver. they have a mylar sheild in the jacket,and they are grounded. Is this god enough, or do I ned to go to RF blockers, or what.
