Balanced power is nice if you can pull it off without introducing other problems. It is useful for lowering susceptibility to noise on the line. Often it is done by using an isolation transformer of some sort. If this is the case, the transformer should not be operated past 50% of its continuous rated power (else distortion will be a problem and that will overshadow any advantage brought by balancing the power).
Thank you, @atmasphere
I’ll keep your reply handy if you don’t mind. Of late where ever I might happen to post on this forum invariably someone throws out the notion of balanced power (and proposes a $2500+ device that purported delivers it) as though its a cure all for things audio plus the common cold.
