I am a big fan of Equitech and their products. Equitech has more info that you could ever want on balanced power. Here's the link:

One thing to note about balanced power. The AC must pass through a transformer (or regenerator in the case of PS Audio) to be balanced. So if you want to feed balanced power to your power amp(s) or TV/Projector you will need a big transformer that can pass the high current needed by your component.
Some of the balanced power products out there use small transformers that will only pass 3 to 4 amps, only enough for source commponents. I like my Equitech because it will pass 20 amps of current, enough to drive all my components, power amps, and projector without breaking a sweat.
I noticed that Equitech is selling their 20 amp Q transformer in a wall mount electrical box for under $500. That is a deal!
