what Stenho is talking about is wiring up 220v power, like you would for an oven or clothes dryer.
the sort of balanced power that applies to audio, uses a large toroid (usually) isolation transformer to convert from 120+/0- to 60+/60-. I have a unit right now from Equitech (the 1.5Q, equitech.com) that does this, it's a monster (80lbs or so), but does 15A of power so the whole system can run on it. If you need less power, Monster cable makes a product that does 5amps or so (HTPS 7000, I have one for sale, coincidentally). Equitech also does breaker-panel style units that can run the whole house balanced. Their expertise is in this arena, they do a lot of BP stuff for recording studios, etc. It definitely is an upgrade to the system, I think - if you can, try one out in your system, the differences/improvements are noticable.
