aniwolfe; thanks for providing more information. The difference between a transport like the Cambridge and the PS Audio, as you surely must know, is that the PS Audio stores the digital data in memory first, and then plays it. I do not want to get involved in computer audio but this seems like a way to get similar benefits. It turns out that the Schiit Gungnir I'd hoped to demo, would cost me $200 (Schiit's 5% fee + shipping) should I elect to return it, which seems awfully expensive to me. I'm open to any alternatives I can demo affordably. I stopped purchasing gear I could not first hear in my system, in my room, years ago. Is the Empirical cable HDMI or Toslink?
