QZ, you would be amazed at the sonic improvements when having one dedicated line per component does. The amplifier should have it's own 20 amp dedicated line, while the cd player and preamp should have their own 15 amp circuits/lines.
The cd player needs it's own line because of the digital noise it injects back into the wall. If your preamp and/or amp share the same circuit/lines, then they will be infected with this digital noise and your sonics simply will not have quite the pristine sound they may be capable of.
The amplifier needs it own circuit/line to provide enough dedicated power for those dynamic passages. Especially if you have a high-current drawing amplifier. Sharing this circuit with even a 36 watt consuming pre-amp may be just enough to flatten the macro-dynamics enough to strip away the life of the presentation.
Everything else can share lines, but to maximize your minimums, these three components should have their own circuits/lines.
And since you are building from scratch, it should cost you about $100 bucks to do so.
-IMO
