AC Regenerator

@sacresta ... you mentioned NYC in one of your earlier posts in this thread.  If you’re located here (as I am) — or in any urban environment — then I think your interest in a regenerator is especially warranted.  I’m in Brooklyn with sometimes OK AC and oftentimes awful AC.  I started with a PS Audio P3 and now have a P5.

I noticed the benefit of regeneration immediately, but it took upgrading to realize what I had.  After removing the P3 from my system, and while waiting for the P5, I remember struggling to listen to my system at all ... it just wasn’t all that pleasurable after experiencing my system on regenerated power.  It was frustratingly variable and usually struck me as harsh and unfocused.  Getting regenerated power back in my system was a huge relief.

Overall, PS Audio was/is a dream to deal with, and you may find a unit in the P3/P5/P10 series or the newer P12/P15/P20 series to be indispensable.

please see below buy these 2 and your power will be heavanly good plus safer than ANY regen. and lots more capacity for your Amps too.

PS Audio...that’s it.
By now you should find some nice deals on used P5/P10 units.
Don’t hesitate, when it comes to clean power PS Audio is the way to go. After I’ve tried the P5 "I couldn’t live" anymore without a regenerator.
Not to mention their customer service, it's one of the most effective and proactive I've encountered in this business. In my book that counts. A lot.
