Anyone hear both Parasound JC-2 and Pass XP10?

Or XP20? I've been quite happy with my X1, except for not having enough resolution in the volume control. I passed on the chance to get a X0.2 a while back, but with reports of the XP series apparently sounding better than even the X0.2 it's got me thinking again. The JC-2 seems like it might be a comparable preamp. Hoping someone out there has heard both and might lend some thoughts.
