excessive hum-buzz in speakers


I have a sony 400cd ES changer connected to a classe cp35 preamp which is connected to a sunfire stereo amp which feeds a set of carver alIII's

The classe has an mit a/c cord and my whole system is connected to two panamax 1000's which connect to a hospital grade wall switch.

I also put those funky cardas rc plugs on every unused rca input connector on the classe and the sunfire.

But still I have some serious hum coming from the speakers.
Before, when I only had my yamaha rxv 2095 with the pre-out mains going to a carver tfm35x and a pair of psb golds, my system was relatively quiet. Although the overall sound has improved, the humming is driving me CRAZY!!!

Please help!!!

I usually find that a cheater plug on the preamp (and/or antijitter box) usually does the trick unless it's one of the older Sunfires. The original Sunfires had buzzing problems and there is a fix for it. If you plug just the amp in (and speakers, of course) and still get the buzz, give Sunfire a call; they should be able to fix it for around $165.
