I recently set up an Acurus A200x3 amp to power my Opus speakers. There's an annoying buzz that's quite loud. A friend's troubleshooting guide for his amp says that amp based buzz/hum is due to AC line noise. Ideally the hi-fi stuff should not be on the same circuit as halogen lamps, light-dimmers, large appliances (esp. with motors, frige, microwave). If that's not possible, there are power conditioners that can be bought.
However, my apt has 20 separate circuits, so the washer/dryer, fridge, stove, microwave, dishwasher, etc. each have their very own separate 20 amp circuits. There are two separate outlet circuits in the kitchen, both 20 amps. The rest of the apt uses 15 amp circuits for outlets and lights.
I suppose the kitchen circuit that I have the amp plugged into might also serve the halogen lights mounted on the ceiling. However the buzz is there even when the lights are off. Argh.
I'm hoping a power conditioner will solve this problem. I looked at specs on a Rotel power conditioner, and its output is only 12 amps, and I need 15. So I need to do some research on what the best conditioner would be for my purposes and for the money. I'd rather not spend more than $120 or so.
Anyone have opinions on these
Furman conditioners? I can't see what the difference is between the $55 M-8, and the $159 PL-8 II.
