Pass X-2 preamp, what's it like?

Hi. I'm considering buying a Pass X-2 preamp but haven't found a review anywhere and can't listen myself as there are no local dealers. Has anyone heard it? What do you think? My system: Meridian 508.24 Melos SHA-Gold (about to be sold) Pass Aleph 3 B&W 805 Nautilus Tara RSC Prime interconnects Kimber 8TC bi-wired. Thanks, Chris
