Clean AC power

+1 @builder3 

The problem living in a narrative driven "reality" people become accustomed to making up whatever story they like regardless of the truth, it becomes "their truth" and on they go their merry way off into fantasy land.

I never said be casual. I said don't be a fear monger. 

Including slimy twist the words around fear mongering.

AS an ex-pshrinck, I suggest you spend as much as possible, because you will need all of the placebo effect you can muster to miss any "noise".

I have been a long time believer in the benefits of AC regeneration. I used to find that I would get the best from my system late at night, especially in the Spring and Fall when the demand on the power grid was at a low point. For the last several years, I have had a PS Audio P20 in my system and regardless of what time of day or season, I get super clean power with a very low impedance-and my system sounds consistently great. This is a fantastic product and in addition to helping create an incredible sound stage and amazing micro detail, because of the low impedance and ability to deliver peak power, I don’t experience compression with loud complex musical passages that were a problem in the past. I have tried all kinds of filters and some very expensive conditioning products and I prefer the P20 hands down. One other point, I do have a dedicated 20 amp line with #10 gage shielded wire running to the P20.  Also, the AudioQuest Hurricane Power cords don't hurt.  I never believed in power cords having an tangible effect until I did some A/B with the AudioQuest Storm line.  Don't think I would drop $30K on the Dragons to outfit my system but any of the Storm series is highly recommended.  

Get a good dedicated lines.
Do not plug amp into filter box etc.
Go directly into the dedicated line outlet
