Gjkphd, I am so not an expert on this, it's ridiculous. But, here's my 2 cents:
First of all, if you have an old fusebox, & you plan to keep the house for awhile, it's probably worth it to upgrade to at least a modern 100 amp main panel w/circuit breakers, regardless of your audio issues. (Like Viridian said). Spending a lot of $$ on dedicated lines when you have an old fusebox seems to me like worrying about which Pirellis to buy for your Model T. But that's more of a homeowner's perspective than an audiophile's.
And yes, probably some things like a refigerator, or fluorescent lights, are worse to share the line with. (Hello!) But maybe tell us more about your system, your budget, etc.......
