OK, I do a similar thing myself.
I have a 10kva 480v to 240v transformer that I run with 240v in and get 120v with a center tap. I have all AV electronics in the house on this balanced power sub system. I can get 6kva in theory as building transformers can typically take 150% load all day long.
Looking back I'm not sure if the balanced power really make that much of a difference. Some data I have read is a 10db noise floor drop, which some people don't think is worth the effort.
But the big transformer does make an excellent surge suppressor.
(Yes, I do realize a wired in balanced power system is not legal code wise in a residential setting.)

I could be mistaken, but I thought there was some provision in the code for balanced power.
It requires double-pole breakers, since both current-carrying conductors are live.
Yes, there is, article 642 IIRC. But it also specifically states such an installation only in industry specific commercial facilities.
