dedicated outlet cost

also I've heard dedicated outlets separated by power and pre amp,
or digital and analog? How should these be plugged in? Poweramp, preamp, cd player, dac.

The non-definitive, definitive answer: plug analog components into one dedicated outlet (amp, preamp, turntable, phono pre), and digital components into another dedicated outlet (CD, transport, DAC). The reason is that you want to isolate digital noise/hash generated by the digital components from contaminating the power supply of the analog gear.

Tvad, what about keeping source on one circuit, and power hungry devices (amps, etc) on another. i know...MANY views on this..just curious of yours

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.

If you are speaking of analog sources, then I don't see why putting them on a separate circuit would be of any benefit unless the amps are drawing close to the 20amp limit of the circuit at peaks, and the addition of the analog source would starve the amplifiers of needed amperage. Analog sources don't draw much power.

Putting a digital source on a separate line is recommended for reasons previously stated.

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!
