dedicated outlet cost

I'd add, in an ideal world, that the video, i.e. TV or projector, ought to have a separate circuit also. I don't know why, but from playing around with my three dedicated circuits, I ended up with a better picture, it was deeper and had a more vibrant color. (I should add that, deplorably, I still have an old 'big screen' tv). I'll let the experts figure out why. The disadvantage, of course is cost, not only the additional run, though that's relatively small, but the extra PC or surge/spike protector.

I totally agree with Tvad.
I actually have 3 dedicated circuits. One (20A) for digital, one (20A) for Analog and a 3rd (30A) for my Pass Labs X350.5 Amp.
The 30 Amp circuit is overkill but my Amp will never starve!

so, i have just a 2 channel system, no video at all. ive got 2 dedicated outlets...only 1 digital component, my cd player. should i separate it this way? ive currently got my 2 amps and power supply for turntable on one circuit, and my phono pre, regular pre, cd player, and tuner. think id get much impact putting cd on the circuit with the amps? None of my gear draws a lot. im more concerned with source, preamps, and quality of power, not quantity as i dont need much...
