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!

Albert, do you have a before and after story on the sound? How much better was it after the "extreme" electric? Does your system always now sound like Sunday morning 3AM.(no I am not kidding). Very late night electric is way way better sounding. I think most of the "gremlins" where folks love their system one day and can't get the "magic" the next day, are all mostly due to electric variations.
Dimmers, even Lutron, are all a nightmare in audio. Halogen track lighing is even worse. The buzzing can even be heard on the lights themselves. Arcmania's post is dead on.
