Amp "Hum" caused by dimmer switches

Khaki8 and Brentski71. Yes, I am using a line conditioner and have fourteen dedicated runs to my audio system as well. I did not have any noise problems before the line conditioner or the Quiet Lines, however there was a performance gain with each of these.

I witnessed an active demo showing Quiet Lines plugged into a noisy outlet on the main floor at CES, whereupon some very obvious buzz and hum was reduced to inaudible. This was what made me think about your situation. There were hundreds of electrical powered things going on, not to mention the lighting. I thought that if it worked there, maybe it would help you.

The comments by Bob bundus are probably correct. The quality of the dimmer is a likely source of the hum. I have no way of knowing which of you (could/ would?) replace this noisy dimmer yourself. Electricians fees and markup on parts could easily run half the price of a set of Quiet Lines. This is why I suggested getting a set for trial, before investing any money.

If you have no other source, I would let you try my filters and see if it fixes your problem. I would prefer shipment by air each way though, so I could return to normal pretty quick.

Albert,
So where do you get Quiet Lines from?

Dimmers only cause problems when on. Turn it to the "off" position while listening. Problem solved.

I had the same problem when I installed a Krell 300i into my system. I started disconnecting interconnects,etc one at a time and it came down to the only piece that had a 3-prong cord which was ny new Krell at the time. Using a cheater plug cured the problem, but shortly thereafter I purchased a Tice Elite plc and no longer need the cheater. Now everything is real quiet.

If the dimmer is the problem, you should remove the dimmer, no line conditioning treatment is as good as removing the source of the problem altogether. Try getting a few lamps for the room to give you different levels of total lighting in the room. If you guys really want to hear how bad dimmers are for your system, turn a clock radio to an AM station and then turn your dimmer up and down. If you really must have a dimmer, get one of the stepped dimmers, as a fixed resistor does less damage than a variable resistor, but still damage. For the record, I have no dimmers in my entire house, one dragged out argument with my wife, and years of improved listening as a result, well worth it.
