PS Audio Power Plant 15........

Just got a PS Audio Power Plant 15 that I bought as demo from a dealer. The idea was to upgrade from Audioquest Niagara 1200. 
As soon as I hooked it up to my system ( Auralic Altair G1, Pass Labs Int-60, Audio Note J-Spe Speakers) I was robed of my beautiful midrange and the soundstage that was open and 3D holographic became 2D and receded to the back of the front wall. 
Did several a/b tests and it became ever so clear.
What could be going on? Obviously, changing from a 1K unit to a 7K unit one expect an improvement.
Thoughts and comments are appreciated.

I recently added a PS Audio Stellar Power Plant 3, and I'm astonished with the improvement in sound. Much bigger soundstage, better dynamics and separation, a just-right smoothness and ease to the music. Note decays ring on and on. I knew that the AC here in my old Chicago building was pretty bad, but I didn't expect clean power would make such a big difference. I'm sorry you aren't hearing an improvement. If it doesn't improve with some more time, I would try another unit, if possible. Good luck.

bbenzaquen6343,  I know this is ancient history but what did you finally do?

I find ANY AC filtering or regeneration whatever, negatively affects my AMPLIFIERS so I only use them on sources.  Most of my turntables come with

speed controllers that regenerate ac internally and IMO need no addtiional ac prep. All the ac filtering and regen devices have 

high current amplifier outputs but again I prefer not to use them.  I am a rural

listener and dips in ac levels are the predominant issue here.  The ac lines to my primary system are dedicated back to the panel box.

I found that my P15 made all of my low powered gear sound great but cannot handle a high powered SS amp. It killed the dynamics when using with my old Coda #16. Plug directly to the wall and get a dedicated line from the panel if you can. It made all the difference for me.
