Hi Rocky. To best understand "balanced power" I suggest going to the Equitech website. They have a patented design which maximizes the noise reduction capabilities of their transformers. Basically they split the 120V AC signal into 2 60V signals and cancel all common noise and some differential noise. If you read the client list it includes NASA and the National Science Foundation; plus the US Navy which requires super clean power for sonar. I'm impressed. Hope you find it interesting.
