Hi,
I agree with Stenho, don't know about the light being a grunge filer. I have a dedicated listening room with large SS amp, cd player, and N802 speakers. I tried using existing power which was the same as yours 15 amp circuit multiple plugs daisey chained and a ceiling light. I noticed at night that while playing demanding music the light pulsated to the bass. Needless to say it convinced me that I needed a truly dedicated circuit. My electrician recommended a isolated ground mentioned in one of the post and 10 gauge. True you only need 12 gauge for 20 amp but if you are pulling a new circuit the wire will be the cheapest part of the upgrade. I went overboard and pulled stranded 10 gauge copper which I had cryoed along with the new breaker. In a word it raelly made a difference.
Ps: If you are running a dedicated circuit consider using 10/3 that way if you have room on your panel for two new breakers you can split your analog and digital. I ended up with a quad wall plug 20 amps each side.
