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!

I had similar thoughts to try the quietline products, as my house has not-so-good wiring. I didn't want to spend 250 bucks on them and local dealers didn't have them for me to try.

I found the music direct has them individually for 27.50 each so, you can try 2 or 3 and see if you like them. (am in no way associated with music direct). shipping is cheap, and fast. Some indiana-based company has them advertised in stereophile for 24.99 each. can't remember the name though.

I thought they improved the picture on my tv a bit. a little less "snow" on cable.

Hope this helps.
