Power regeneration - good idea? PS audio?

I talked to Torus and they say that noise <20kHZ is not filtered out. Regardless what the measurement says, I think the acid test is whether it sounds as good during the day as during the night.

@atmasphere , do you use P20 for your system? If so, do you plug in your preamp and amp into the same P20? Some people use separate power conditioners for the amp vs the rest.

thanks, Jay

@atmasphere I have Torus RM20 power conditioner, but I am not sure if P20 will lead to actual SQ improvement. I still hear a significant improvement in SQ late in the evening (with RM20). I am looking for conditioner/regenerator that will improve the day time sound to equal that of the night. I thought P20 was the answer until I read some mixed reviews on P20 on whether it is actually better than a good conditioner like Torus.

I think it would be interesting to measure the distortion level at my home. Can anyone recommend a meter for this?

@atmasphere , Do you think P20 will improve the sound of your bigger amps like MA2 or 3 on P20 regenerator? I ask because you specified that P20 works well with your "smaller" amps.
