Pass Labs XP-10 & XP-20 preamps

Hi AudioFeil, I think that the XP-20 was used at a couple audio shows in Europe a few months ago and I was hoping that perhaps it has been shown (and heard) at a US audio show as well. The XP-20 lists for $8800 and Pass Labs told me that it sounds better than the $10000 list Pass Labs X 0.2 preamp. I currently own a X 0.2. Thanks! Stan

The X 0.2 was first introduced in 2001. The X-1 was first introduced in 1999. The X 2.5 was first introduced in 2001. The X 0.2, X-1 and X 2.5 have not been discontinued. Stan
