A buzz in my speakers-Ideas???


My system: Pass X-250/Martin Logan Ascents/Rotel 1066 Pre/Pro- Phillips 963sa/Adcom 5503 3/ch amp-Pioneer 50" Plasma/Monster cable 5100 power purifier/surge protector. My source for TV is Direct TV. I also have 6 dedicated 12-2 romex lines for each component into 6 hospital grade outlets. With these components in place my sytem ran dead QUIET. No hum/no buzz. I recently sold the Adcom and bought a Krell KAV 3250-With the Krell in the system I had an annoying buzz regardless of which outlet it was plugged into-and regardless of the speakers it was hooked up to. When I plugged it into the Monster 5100-into the outlet labeled amp-all was quiet. I've read often that a contraption like the Monster 5100 will choke the amp. Furthermore I ran individual dedicated lines/circuits so I can utilize them-not avoid them. Any help would be appreciated. I'm in the process of running one more dedicated 10 guage line on a dedicated circuit just for the Krell. Its in a basement so its very accessable.
My questions are? Would it be worth it to install a new ground rod-so that I know my panel is properly grounded?
Would an isolation transformer possibly remedy this problem?
Is their a power product(regenerator????)that might help without choking the amp?
BTW-all these questions are being asked under the assumption that there is nothing wrong with the amp. Which is also being checked out as we speak by Krell. Any and all help would be appreciated.

Thanks for all the responses. I'll check out that Torus conditioner. Thanks again.
The thing I don't understand is it DIDN"T buzz before with the Pass X-250 and the Adcom 5503. Even know with just the Pass hooked up its dead quiet. BTW- I did check out that Torus conditioner. I'm not sure what it costs-but it looks real exspensive..........When I get the amp back-hopefully one of the above tweaks will work. I'll try the cheater plug-but it just seems like that defeats the purpose of all the power tweaks I've already made.
