mood lighting

There are many respectable solutions to choose from. Try walking through thr lighting dept at Lowes and Home depot or your favorite local lighting center. You may be interested in spot specific lighting which uses battery power and can be placed anywhere you need it as long as you have a surface to adhere it to. I have found this to be very useful in my set up, just a tap and you have instant lighting of various watts to accomodate your needs. The battery power has no ill effects on sound or powerline noise. (use rechargeable lithium batteries for value)
Great for task specific needs. Look also at track and rope lighting solutions for something different.

The glow of my Cary monoblock tubes(12), and Synergistic Research active shielding LEDs(8), is all I require, to set the mood for music listening.

Best to listen in the dark, no visual distractions. When you can't do that, just use 'peepers', like from a sun tanning room. You will be surprised what 'blackness' does.

I have four ceiling cans on a dimmer and just added some halogen track lighting specifically for my audio rack. The track lighting is on its own dimmer. When I listen to music the ceiling cans are off and I adjust the dimmer for the track lighting to match my mood.

The dimmers are on their own breaker.

Funny, I just realized that I have no room or place in my listening room for a normal lamp.
