Hi Mike. Power conditioning, for me, has always been problematic; I never quite find anything I really like. Did the Bybee stuff, Sig and Pro, then did Audio Magic,...don't really like it that much either, but there it sits all these years later. Since last May, I have a new home and, thank God, it has a super low electrical noise floor, so I'm just lucky there (my last 3 homes were horrific). There always seems to be a subtle denuding of harmonic richness, etc. to these conditioners. But, of course, I haven't tried the new ones. Your Nordost QRT caught my eye...here's a story I forgot...30+ yrs ago, I'm 28 or so, and did a stint at TAS. I did the first PC review there and was always looking for stuff to drive people crazy. A nice guy, Bill Stierhout, got a hold of me, or I ran into him somewhere, can't recall, and gave me the next crazy box. I took it home and, jeez, it worked. Very subtle but there (I was running 50W SETs all NOS tubes on Quad 63s at the time, so I could hear pretty deep into the noise floor back then). So, I reviewed the Electraclear box but then, last minute, even after the galleys, mercurial Harry pulls the review. I never asked why, really didn't care, I was about to quit anyway, but then ended up at dinner with Harry in Vegas. He asks me to sit next to him and sheepishly says he's sorry to have pulled the review. He's surprised that I could care less, but then says the reason is because he popped the box open and there was nothing inside! I said, whatever, pass the salt. That review is still in a box somewhere in my basement, or lost, and then I see some years back Nordost, of all people, have grabbed the tech from Bill and stuck it in a new box! I actually think Bill's at it again, the exclusivity clause with Nordost must have tolled....a place callled ADD-Powr. You might want to check it out...I still have a couple Symphony Pros hidden about, one even on my Pioneer Kuro plasma TV...makes a subtle, impossible-to-find-elsewhere, difference, in a good way. Oddlly, though, one only really notices the difference - like a subtle tension is released from the system - until you take it out. A few days later you're just not as interested in your rig as before; put it back in, wait a bit, and back comes the...feeling, like those best late at night listening sessions. Easy to see on my TV, though. Now I'll go back to my denying-that-any-empty-box-can-do-anything mode; it seems to work best at cocktail parties...
