There are others here with real technical expertise in electrical systems, I can only respond anecdotally. When I moved to a new/old house, I installed an entire subsystem for the electrical, and even before the big isolation transformer arrived and was installed, the wiring was connected via a "J’ box (presumably a "junction" box). The system was largely the same, but the room was different. And, yes, the system sounded a little bright at first, but the power here (I’m now in Austin, very close to downtown, and not far from a lot of commercial stuff, though in a strictly residential neighborhood) was much cleaner, without any treatment, conditioning, etc. than what I was getting in NY (not in Manhattan but in a small village north of Manhattan).
Part of it may be the result of newer infrastructure, or who i'm sharing a transformer with- i know I'm not on the same transformer as the apartment buildings nearby.
So, the power coming in is certainly going to have an effect, as will the amount of demand on the ’grid.’ It’s been upwards of 110F here and I can still play the system, but I know it would probably sound better, despite the isolation transformer, if the incoming power wasn’t in such great demand right now due to heat.
As to ’running next to,’ how close? I think there are best practices in terms of spacing the lines. I’m not going to address the use of a 30 amp breaker since you may have some need for that.
