"It might be worth trying out a power conditioner or a current stablizer."

Thanks for the suggestion; will a computer UPS work for testing purposes? Or would I need something specifically for audio equipment? Right now I have a Monster Cable power strip which supposedly provides "clean power", but it has no internal battery so I can't see how it could help if the receiver and other equipment is drawing too much current.

I have a computer UPS and am quite familiar with those - not familiar with solutions specific to audio equipment.

Thanks,

Doug
