Electrical question re dedicated line

In my home situation(new house) the electrician who came by to install a dedicated line said it would be too difficult and very expensive. Another electrician said that I could have a dedicated line but it would be external and would travel accross the outside of my walls(insulated of course) and would have a little box for the receptacle outside of the wall on the wall. My question is that the fact that my system is on a circuit with it's own breaker, is that kind of like a dedicated line? The breaker my system is on has 4 seperate receptacles on it in my room but only my power regenerator(PS P500) is conected to one of those receptacles.In other words, all that is on the circuit that goes to the 4 receptacles in my listening room is my P500. The other receptacles are not in use. Is that kind of like a dedicated line? Would there be much advantage to doing what one electrician said was possible and have an externaly run dedicated line?
My system is :
Pass X250 amp
Pass X1 preamp
Talk Electronics Thunder3.1b CDP
Hales Transcenence 5's speakers
PS Audio P500 power plant
Shunyata Aries and Lyra interconnects and speaker cable
Prototype power cords which were not given a name but are good as I've compared them against Shunyata King Cobra V2 and Synergistic Designers Reference and much prefered the cords I have.
Any help would be valued. Thanks

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.
