HenryHK, I forgot to mention that during the Panther/Sky X-01 audition the X-01 was powered through an AudioQuest NRG5, which in itself accentuates treble response. In the Cardas Neutral Ref vs AQ Sky situation I have had the X-01 equipped with its own stock powerchord, which puts it at a relative soundstage, imaging resolution, and sweetness disadvantage if compared against players equipped with an aftermarket chord. In either case, I have been concentrating on RedBook performance, as I own but one single SACD. I am not in a position to offer any meaningful findings on SACD performance of X-01 yet.
IUJONA, I have had several occasions to audition equipment at SoundBySinger in NYC and always been delighted by their professionalism. My first exposure to X-01 was in fact at Andy Singer's shop in NYC as well.
