@steakster , @dancarlson10 , interesting discussion around Nordost. I too am rapidly developing a neurosis around noise, as my system taunts me after midnight when everything is fantastic. I know precisely what you are talking about @steakster when you can hear the air and subtleties around the instruments and not just the instruments themselves. Once you hear it it is impossible to go back, at least in my case!
@dancarlson10 it sounded as if you had some other grounding device besides the QB8, "All you need is a qb8 good grounding device after that", but probably just my misinterpretation. I don’t quite get the QB8 "primary ground" thing, and how this is any different from the ground on the other outlets.
Also - if I don’t require the added "conditioning" to be rid of AC noise after switching to dedicated 20A lines, I really, really like the Nordost approach of not adding or subtracting anything from the tonal balance. That said people say the same about Torus too, I think. Wonder how my fancy Audioquest Dragon HC cables would work with Nordost QB8 though. I did try the Valhalla 2 power cord and unfortunately found that bass was lacking vs other cords, with my Diablo 300 (my dealer said other Gryphon owners reported similar complaints with the V2 cord). My V2 speaker wires are second to none though. Except Odin of course!
