Equi=Tech Balanced Power vs. ?

Having finished my equipment purchases (for the time being), I have decided now to explore enhancing the electrical power in my media room.

PS Audio recommends regeneration; Richard Gray Power Company recommends having power in reserve that is added when the draw exceeds available capacity. Equi=Tech has an altogether different approach: balanced power.

I am writing to ask whether anyone has had an experience with Equi=tech/balanced power. I do note that none of their units has appeared for sale on Audiogon in recent weeks, which may be a positive reference of a sort itself. Moreover, has anyone had the opportunity to contrast the alternatives cited above?

Thank you.
