Power strip recommendation.

I have had the PS Audio PPP in my system for sometime now with absolutely no noticeable sonic improvements. I just had 2 20amp outlets wired directly into the panel with 10awg gauge wire with i must say better and satisfying sonic results. Much reduced noise floor. As far as i can see/hear, the power entering my home is already very stable and "clean".

Long story short, i will remove the PPP but would still need a hight quality power strip or perhaps a passive device like Audience but i am skeptical that such passive devices would reap any sonic benefits either. I am looking for the BEST return/value for money and i believe that the power strip option is the way to go. My equipment is all ARC Reference.

Suggestions welcomed.
