I would recommend the following regardless of internal or external house wired:
1. Install one 20 amp dedicated line for your amp. There is a distinct possibility that the X250 draws more current than similarly powered amps. Marty DeWulf of Bound for Sound seems to think so regarding this amp. Regardless, any amp close to this current draw should have a 20 amp circuit/line so as not to potentially limit the current draw during demanding dynamic passages.
2. Install a 15 amp dedicated line for your digital source. A digital source injects much noise back into the line and will pollute any other component sharing the same line.
3. Install another 15 amp line for your preamp. Again, you do not want anything sharing the same line with your power amp. Just a small current draw of 35 watts (typical of a pre-amp) sharing the same line as the amplifier can be just enough to strip away and flatten the dynamics of demanding passages thereby potentially rendering the presentation rather lifeless.
4. Now that you have 3 dedicated lines, I'd recommend selling the multi-outlet PS500 and then purchase three dedicated passive line conditioners that have no practical current limitation of it's own and simply cleans up the AC.
5. Request that the electrician install all dedicated lines on the phase/leg that has the least amount of motorized appliances.
If you haven't already thought of it, you may as well have the electrician install some audio grade outlets while he's there.
-IMO
