Does your system do things better in the dark?

I believe it's 3 things:

Less noise on the grid.
Less sensory input.
Attitude.

What I mean by attitude is demonstrated when I tell a visitng non-believer (non-audiophile) that they will appreciate the music more if they just relax & listen, in the dark.
If they can't even stop talking for at least a minute,
I believe they aren't even trying to relax & just listen.
If they can't seem to relax, I'll ask them to close their eyes, even in a dark room. If they debate this request,
I won't waste any more of my time trying to prove the point.

LOL Byfo, u are a sick puppy.

Enhanced focus on the music is likely 99% of it. In terms of the quality of the AC power, I wonder if people notice poorer sound in the middle of a heat wave when power demand is higher (assuming no brown out)?

Listening in the dark is essential. Luckily I discovered this early on. If you really want to experience crazy imaging and 3d life-like soundstage try smoking the pipe.

Neither Meatload or Madonna has fallen asleep on me.
