Clean AC power

nonoise, what specific methods and/or gear are you using to clean up the power? Thanks.
 

@nonoise,

Thanks. The improvements you report are just what I'm wishing for. Was hesitating on regenerators, with PS Audio's entry-level being double the price of the Audioquest. Believe I will start just where you did and, with luck, maybe need look no further.

Doesn't keeping your audio components on a dedicated circuit protect them from noise generated by other household appliances? If not, what purpose does a dedicated circuit achieve?
