Amp "Hum" caused by dimmer switches

I just recently got an Acurus 100x3 amp to drive the front 3 speakers of my home theater system and I am disapointed to find out that my room light dimmer switch is causing a very noticeable "hum" that can be heard from the listening position when no audio signal/ low passages are present. I did not have this problem using the amp in my harmon/kardon receiver. I do not want to remove the dimmer and go to an on/off switch and do not have the money for a power conditioner. Am I out of luck and have to resell the amp? I bought it used from this sight so I can not return it. The amp sounds very nice when the lights are not in use. I'd love to get some sound advice! Thanks! Brentski71  (Threads | This Thread) 05-01-01

Sounds like you have an absolutely killer system in every way possible. I hope i didn't come across as criticizing your suggestions. I've always found your comments and writing style completely enjoyable and well worth paying attention to. While I was simply trying to cover the simplest and least expensive stuff first, I can understand your suggestions also. Like you said though, not everybody thinks or does things the same way. In that respect, it would be better to try some basic filtering before unloading the amp.
