Seeking advice on power conditioners/regenerators

I just put a PS Audio power conditioner in my system and it completely transformed my sound in a way I truly wasn't expecting. I see you already own their phono preamp so you must be somewhat familiar w/ their products. 

I did quite a lot of research before I bought mine so I could make sure I was spending the bucks wisely. I'm much more about doing things correctly the first time, so I don't have to spend yet more bucks on an upgrade. 

As part of my research I explored different companies approaches to the power conditioning issue, and determined that PS Audio's power regeneration is a very solid approach that consistently yields outstanding results, so say tons of reviews. Apparently the only exception is if you have a certain type of esoteric amp. I'm using a high end integrated A/V receiver in my home theater system which doubles as my two channel audio as well. I was sort of floored when I put it in my system. 

It was truly like everything coalesced.I guess I had been on the periphery of really good sound all along, but this thing crystallized everything. It took away the hard edges in a way I didn't think possible, brought out a super dark background for the music to come thru, and gave my soundstage a three dimensionality I personally had never experienced. 
I would venture to say, from the looks of the equipment you've chosen that the effect would be similar for you. 

One more thing. I encourage you to explore the Multiwave feature. I, personally, believe that would be sort of a reason in itself to go with PS Audio above other manufacturers.

I chose the P15 but that's b/c I didn't want to have to upgrade. My understanding is that the P3 will get you pretty much the same degree of improvement in sound, but with less power and fewer features. They have both a generous trade in program, and also a 30 day return policy. How could you go wrong? 

Most audiophiles have found that many of the power conditioners/surge suppressors on the market do a great job on source components and preamps but limit the dynamics and bass impact on power amps (and integrateds) and subwoofers. This is the result of dynamic current limiting due to series filtering/surge components (inductors, etc.). The solution is to incorporate power factor correction (energy reserve), but doing so increases cost considerably. As one example, the Audioquest Niagra 3000 costs $3000.

Most audiophiles on a budget opt to plug amps and subs directly into the wall outlet and use a power conditioner for everything else. The Furman PST-8 at less then $200 is a popular unit.

Whichever way you go, make sure you purchase with no-cost return privileges. Good luck in your search. 

The Telos Quantum Resonator Conditioner is not in a "value price category" but does an incredible job in opening up a system.  It incorporates 6 Dueland capacitors and automatically runs a demagnetization process every 15 minutes, ensuring that 'sound-destroying' magnetic fields are constantly being controlled.  Major improvement over my previous Shunyata.  Unfortunately it approaches 20K.

I’m on SDG&E too and have solar. The AC line quality SUCKS! I use a Shunyata Hydra 8 and it does a good job. 

If you size the ps audio regenerator right it will improve your amps too. Conditioners are notorious for limiting amp sq and if you get too small of a regenerator you will be doing the same thing. Ps audio had an in-home trial policy so instead of guessing or asking for somebody’s opinion, get 1 and listen to it and buy it if you think it works in your system
