I have a 55 year old house with an original 100 amp service which, in a way, worked in my favor because I was forced to upgrade. I did this approx 15 years ago with the addition of a 200 amp box bypassing the old one to serve 220V users such as the clothes dryer, stove and A/C air handler. The 100W box was otherwise left unchanged feeding all other existing circuits in the house. This was a matter of convenience because the 100 amp box is in the garage.
Modifications that were made to serve the sound system were done primarily to protect it, to the extent possible, from potential damage from power feed glitches. I didn't consider it from the standpoint of maximizing sonic quality and it still wouldn't be a priority in my thinking today. Anyway, the modification consisted of a lightning arrestor with surge protection and separate 30 amp breakers from the 200 amp panel serving two outlets on the wall which serves the system. I also use a line conditioner for most of the components in the system. I'm sure that there are some purists that would cringe at all these intervening electronics and several have already reminded me that this protection may provide some peace of mind but is mostly not that effective.
From a purely sonics standpoint, and I'm still not convinced that this is an important issue, I may have gained something by accident. The electrician did use 10 gauge Romex from a roll on his truck and the run of these two wires was relatively short (approx 25ft). They were run in the garage attic, parallel to one another with no crossing of other conductors, and the installation in question was far removed from "noisy" installations such as the central air handler by about 60'.
I don't think I added much to the conversation except to remind those who are doing upgrades to their house power, that it's a good idea and pretty simple, to make accommodations for your sound system at the same time.
