I have used Pass X2 (original) and X0.2 with both X150 and X350.5. X0.2 is noticeably but not earth-shatteringly cleaner and quieter. Both preamps paste a big grin on my face, and the X150 still rocks big-time. Of course, X0.2 + X350.5 is "the" combo to beat here in the Weasel Works. Should I sample XA60(.5)s? hmmmm...
cheers apo
ps the X0.2 is the, Best, headphone amp, like EVER. Cooool.
