Who buy PS AUDIO ?

@tomcy6   Yep.  That is, for me, the true value of the PS A regenerators...that I get stellar sound at all times of the day.  That's why they're worth the money.  Life is too short to be limited to a couple good hours of listening time late in the evening!

@tomcy6   Light is not an issue with me because I have a dedicated basement listening room.  It's always dark down there!  State of mind always plays a role.  If I'm not in the mood to listen, then I don't.

With the number of folks who frequent this site it is not surprising to find that some have had less than positive experiences with PS Audio products. 

What attracted me to PS A  was their idea of and dedication to the regeneration of electricity to feed our systems.  I bought into that concept because, if it could be done efficiently, it would put the vagaries of electric quality at bay and allow us to enjoy our systems at all hours of the day not just at night after many local businesses were off the grid for the night.  My best affirmation of this occurred at a stereo shop where when the business next door closed down, you could hear an immediate improvement to the sound.
PS A has come a  l o n g  way with regeneration.  My P600 improved my system's sound but ran very hot.  When the Premiere Power Plant was released I bought into the promise of improved efficiency and it delivered, but quality control was problematic with a high rate of regenerator failure.  Sure enough, mine failed as well.  Ugh.  But... all it took was a phone call and a new PPP was on its way.  That PPP lasted till the P5 became available.  The big change here was that Paul McGowan saw that the Chinese manufactured PPP was not receiving enough QC and thus failure rates were unacceptably high.
What to do?  Move manufacturing to Boulder, CO where the principals could ensure QC.  What happened to the prices of the new units?   They went up...a lot!  But the new generation units were like tanks!  Finally, Paul and Co. came up with what, in my opinion as one who experienced all of the generations of Power Plants,was the most musically significant innovation.  Creating the regenerated sine wave with DSD processing was a true game changer!  It is a huge sound quality improvement over the otherwise excellent P5.  My entire system runs off my P12 and it has never sounded better.
With all of these changes/upgrades, PS A allowed trade-ins for every step along the way!
Finally, Paul McGowan serves the entire audiophile/music loving community by sending out a new video about audio every day, answering a great variety of questions from audiophiles around the world.  His answers are straight forward and frank.  He does not abuse this time to shamelessly promote PS A products.

@jbrrp1  A big +1

BTW... Paul McGowan's autobiography "99% True" is a fun, fast read and will give you insight into his humanity.  Paul screwed up a lot growing up.  Somehow he always manged to escape very difficult circumstances so he and Terri could be in the successful position they now find themselves.
Resiliency might be an appropriate adjective to describe their life journey.  I would love to travel to Boulder to experience his Infinity IRS V system...one of 50 ever made.  From what Paul has said,  when people leave that room they are overwhelmed with the sheer majesty of that system.  He recently improved it significantly by employing Audioquest Dragon power cords.  Even though PS A makes their own power cords he succumbed to the AQ's charms and is now working with Bill Low of AQ to pair specific AQ cables to PS A gear as recommendations for PS A customers.  As a result PS A is selling those AQ cables should folks want to take him up on his recommendations.
A really good guy making groundbreaking audio gear working hard to connect to the music loving public with daily blog posts and videos on all topics audio.
