Several comments on this one.
14 dedicated lines for an audio system ??? Talk about the potential for a ground loop !!!! That would have to be done very carefully. I'm assuming that Albert probably paid as much attention to having this done correctly as he does to putting forth well written and informational posts though. WHEW !!! That one's pretty much a complete breaker box unto itself !!!
Hum, ground loops and noise can be generated from having pieces of gear within the same system plugged into different outlets. This is true EVEN if they are on the same circuit. Try plugging everything into one outlet via a power strip, etc.. and see if that helps at all.
If you have ANY two pronged power cords hooked up in that system that are not polarized, you might try flipping them around. This can sometimes make a dramatic difference in noise coming into the system and lower the noise floor of the equipment itself.
You might want to invest in a polarity checker for your wall outlets. This is a good investment that is valid for things other than just audio purposes. Rat Shack and any decent hardware store will have them. Cost is under $10.
Try using a "cheater plug" or "ground lifting adapter" on the amp. This takes a three pronged cord and converts it into a two pronged cord.
After these simple and inexpensive "fixes", things get more complex as mentioned above. Like some of the others here, i would rather try to stop the bleeding rather than just band-aid the wound. Find a good dimmer and go from there if that alone does not do the job. Since dimmer's are not "audiophile grade" products, they should be MUCH cheaper than ANY "audiophile" type tweak that would remotely make a dent in fixing the problem. Sean
