Voltage regulation

I have an APC H15 that includes voltage regulation. I've seen it light up for both boost and trim on the voltage but it rarely outputs exactly 120 hz. Right now it's reading 121 Vac in and out, but it's generally a little higher.

I don't know if it's more of a sound quality issue or if it's just "hard" on components to have it fluctuate all the time.

There may be some components that will hold it at exactly 120 hz, but consider this a heads up that not all of them will.

George,

Time out for a funny answer. Use the isolation transformer that you bought from me, I believe that it performs voltage regulation as a byproduct of the energy being stored and released.

There are products made for audio that are called voltage regenerators. Generally these units are considered the best surge protectors and I imagine are set to a desired voltage.
I do not think that feeding a high quality internal power supply a steady voltage would reduce dynamics. The power supply circuit should have the ability to respond appropriately to the demands the music puts on it idependant of instaneous current draw. If the power supply is that good though... I get your point, that an external steady voltage should not be required. I can't see how it would hurt however.

Chuck It raises the output voltage by 3V. That pushes the output to 130V. Other than that the Topaz Isolates only. No regulation.
