CJK, a power filter/conditioner puts the incoming AC through a relatively simple circuit which provides some degree of noise reduction. It may also include a provision for surge protection. It does not regenerate power.
As can be surmised from the description I provided earlier, a power regenerator capable of supplying sufficient power for a typical audio system will cost a substantial amount of money. Many (although certainly not all) conditioners are available for much lower prices than most regenerators, or at least regenerators that are well designed and have substantial power capability.
Your question about balanced power is a good one. Yes, the outputs of the power transformer in an audio component will often be balanced relative to ground. (Although keep in mind that the power transformer will often provide multiple outputs, at various voltages, some of which may be balanced and some not, for various reasons). However a main goal, and perhaps the main goal, of balanced power is to minimize noise on the AC safety ground. AC safety ground is connected to the chassis of the component, and much of the noise injected onto the chassis will inevitably find its way to the circuit ground/signal ground of the component. In some components circuit ground and chassis are even connected directly together, and in many others they are connected together through a low impedance.
The components power transformer cannot help with respect to noise coupling through that path, because it is not in that path. And in fact it can itself contribute to coupling of power line noise onto the components grounds, via stray capacitances that will inevitably exist within it.
Also, btw, a major source of the noise that balanced power can help reduce will be the components themselves. See this paper for a somewhat simplified overview, and this one for greater detail.
On another note, glad to see youve made some progress with the problem being discussed in your other thread.
