Charles1dad brings up an interesting point i would like to expand on.
(since i own four balanced output powerline conditioners)
What is meant by "balanced A/C power" is that the usual power (in America) is 120 volts (or so) coming from the wall in the form of one wire/side is 120volts, and the other wire/side is neutral, or 0volts.
If you have played with electricitty, you know the 120Volt side can produce 120volts via the ground wire, just as well as the 'neutral' wire'. The neutral cannot do anything without the 'hot' 120volt wire.
Well balanced A/C changes that to being 60 volts on the hot side, and another 60 volts on the neutral side, so the neutral is also hot now.
This is called 'balanced power' or also 'technical power' And is ILLEGAL inside residential walls in the USA, and only allowed with special signage in commecial properties.
Many audiophile power conditioners convert the standard 120v/0v A/C to balanced 60V/60V power.
Nearly every audio product made will function just as well on balanced power as regular power, and many sound better with balanced power.
Any TT motor, preamp, tube devices, amp CD players. My entire system is run on balanced power.
Even if you don't want a power conditioner, various transformer based products create balanced power with no other cnditioning. (One I know of, but do not own, is the Goertz balanced transformer. (from $250 or so up to $450 or so)
Anyway, a different kind of 'balanced' worth investigating IMO.
