Buzz trnasmitted to speakers from amplifer

You could also take your amp to a freinds house that isn't having any hum issues and plug your amp into his system..if the hum is gone you'll know..............

If you have any low voltage lighting on while your system is on this will cause a low level buzz
The lighting does not need to be on the same circuit just off the panel itself as most people only have one electrical panel in the house.

Thanks for your input. It is a well respected high power SS class A amplifier. If all will forgive me, I would prefer not mentioning the manufacturer, as I believe it is power related.

No change with a Furman IT-20i reference power conditioner...still low level buzz with or without input which gets slightly louder with volume increase. It is not on a dedicated circuit, but only a single light on the same breaker number. I just thought the Furman with it's large transformer would "isolate" from most AC impurities.
Biggest problem with the Furman is it buzzes pretty loud itself (with its transformer) but not through the speakers.

Again, not too big a deal as I am delighted with the sonics of the amp, but was hoping for near silence :)

Perhaps a dedicated circuit may be the only reliable way.

Thanks

Thanks
By low voltage lighting are you speaking of the energy saving fluorescent bulbs?

Any dimmers on the lights,aren't they a problem?Fine is you don't mention names,all i can say if i'm spending money on a amp,any buzz would be a deal breaker,i just couldn't find it acceptable.
