Hi Dennis, I think you know more technically than me, but I never liked transformers - even less than the so-called "purifiers" like the Bybee. Transformers came first - the big Tice's if you remember, commercially - and I always felt that there was some kind of ultra low level...discontinuity, is the only way I can put it (this in addition to the harmonic denuding, which happened because the pressurized "feel" of air, both within the sound projection ans around it, was reduced along with the mechanical artifacts of distortion). It was as if there was a gross distortion removed - the so-called grunge - but then also this subtle tension was introduced. It sounded like a super high frequency oscillation that could barely be heard, so you thought it could easily be ignored, but it couldn't. Hard to "see" if looking for it, but looking out of your peripheral perception, it was always there, and was quite un-natural. Was it the electro-magnetic fields feeding back into the IC's, or the nature of transformers in general, or were they just not good enough then, or...I don't know why technically, objectively, and there might be a good technical argument why transformers should sound better. But I've found that, like most ideas, even scientiific ones, they are good starting points - good pointers towards the truth, some better than others - but not determitive as far as experience. Although, again, I don't claim to be the expert on conditioners because I stopped listening then some time back, just my opinion.
Mprime, I heard the Supratek with an Aleph 3 amp - nice 'lil SS piece - in two systems, both sounded very nice, and particularly with the NBS Pro IC in between, which kept the Aleph from drifting into too much clearness (my experience with Aleph is that you want to accentuate - not tone, but bring out - its spatial qualities. With that approach, it usually maintains its detail/accuracy performance; but if you go for more detail on the IC/PC, you can sometimes end up with an amp that sounds like its not an SE SS Pass design, ie it sounds more "transistorized" so to speak). I had the Aleph/Supra in that later system for three months, but the NBS improved both systems in the same way. Actually, the Supra and Aleph sound quite alike, although the Supra is more liquid. Great dynamics, clarity, naturalness - just like you hear in the Pass stuff vis-a-vis other SS amps - but more liquidity and continuity in the Supra. If you like the Pass, you will like the Supratek.
