What should I expect after installing a new power management system?

I don’t think some posters realise the benefits of power conditioners. Amps should not be plugged into the majority of power conditioners, they will limit current. Low-current-draw components can experience vast improvements in SQ mainly by filtering RFI/EMI, and reducing the noise-floor. Many are capable of isolating noise produced by digital devices so that it doesn’t contaminate the mains.

There are some conditioners that claim to accept amplifiers without limiting current such as PS Audio’s regenerators. I have no experience with these but my balanced power conditioner has increased the performance and enjoyment of listening to music.

@celtic66 , can you tell us what else is in your system and how it is connected? Do you have both a turntable and DAC?

I failed to mention that the amp should use a heavier power cable (~ 10 gauge) than sources for unrestricted power delivery to the transformer and to keep the capacitors charged.

So I watched the VIDEO on ASR. What a shite show, PS Audio really tripped over their dicks responding to ASR. From the review, the P12 does a good job regulating voltage, but doesn’t do much at removing noise or distortion. 

Please clearly explain "subtracting whatever seemed not there, but clearly was."
