My experience auditioning a PowerCell 10 (non-SE, Mark II ?) was a revelation. This power conditioner is a game changer and a quantum leap forward in feeding clean (and, incidentally, balanced AC) power to components.
Like some others, my experience was that even a broken in unit can take a day to settle in. And the tonality and sound-stage of your system will be dramatically changed, but with adjustments these changes are for the better.
At first the sound can be very confusing, I thought it was adding its own synthetic signature. Continued listening revealed this was just my components performing better.
Give it a little while and you'll find incredible silence, extended dynamics and bass, stunning imaging, vast sound stage and greater definition. I also experienced vast improvement in mid-range and treble sweetness, musical flow, detail of inner voice, secondary musical artifacts and detail WITHOUT any added harshness or glare.
The reverb tails are the longest and quietest I've heard IMS and the conditioner seems to contribute an uncanny musical FLOW and CONTINUITY, probably due to lower noise floor.
Removing the PowerCell (and returning to more familiar conditioners) sucked this newly found life, vividness, mid-range clarity, bass definition, depth and space from my system. Other line conditioner now sounded tonally wrong, closed-in . . . one sounded like a blanket dropped over the clarity, excitement and musicality of the PowerCell.
As 'due diligence' before purchasing (a pair of Power Cell 4 SE's actually) I will audition some others (Shunyata, Audience, etc). Even with my limited experience with line conditioners (Bybee mostly), this GAME CHANGING technology that's a magnitude beyond competitors, in my humble opinion.
