Levinson 331 or Pass X150 or Plinius SA-100 ??????

With regards to the McCormack comparison, I own the Plinius SA-100 MK III and a McCormack DNA 125, and though I am a huge fan of the McCormack, I think the Plinius is better in almost every aspect. More open, extended top end, midrange transparency, more low bass, better definition. The only thing I like better about the McCormack is that it has a little more mid-bass warmth that is nice for some CDs. The Plinius has an overall darker sound but is cleaner overall. For the money, the McCormack really shines, however.
