Voltage regulation

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.

Hey Everyone Thanks for the responses. Any recommendations for a sub 1k budget limit (new or used).

There's some 5000VA/50Hz Sola MCR (works even better at 60Hz) on Ebay for $600. Heavy and expensive shipping. Insist on bolted/strapped to palette. These are noisy, so they have to be mounted remotely, if possible. The MCR is only 3% regulation but have much better CMNR than the CVS models. The SolaHD site has a technical/FAQ section that's educational.

Wouldn't recommend a tap-switching regulator for audio.
