Berning ZH 270 and Power conditioning

Question to ZH270 owners: Do you find your amp sensitive to the quality of AC? I get a little bit of buzz from the amp(and not from the speakers) from time to time. The noise's level and pitch change with (i) different Power Cords connected and (ii) as the other electronics and lights in the listening room turn on or off.

How do you suppose I address this issue? I am anticipating the first answer to be the dedicated circuit, which I'll look into, but what else have you found to improve the Zh270's sound? I am primarily interested in the effect of power conditioning (Hydra, PS Audio, Equitech, etc.) and power cords. Any input will be appreciated. Thanks. BTW, my VERY simple and humbe system consists of:

Reference Audio Mods (RAM) modded SACD1000 w/ 3.0V+ output
RAM silver interconnects
Berning 270
FMS Zero speaker cables
Kharma Ceramique 2.0s

Henry,
I've heard that the commonly recommended mods for the Berning include the Silent Source power cable.
On my own amp, which doesn't have the upgrades, I use a Virtual Dynamics PC, and a Blue Circle Music Ring conditioner. It sounds quieter w/the conditioner than without. Either way, I'm feeding to a FIM outlet into a dedicated line.
I'd like to try some other PCs, but haven't had a chance to yet. Hope this helps a bit...Spencer
