New Musical Fidelity M8 pre - anyone heard this

I am in the market for a new pre. I have recently listened to the ML326s, the Parasound JC2, the Pass Xp20 and the MuFi M8. Of these its between the XP20 and the M8. When I listened to the M8 with its matching M8700 amps and Dynaudio confidence speakers I found the system amazingly transparent with what i thought was more detail and information on my standard test tracks than I had heard before. But listening to the Pass with Pass xa160.5s and Wilson Sophias and comparing with the EMM Labs Pre2 the Pass also had great transparency and detail. My problem is I have not been able to compare the Pass to the M8.

So...has anyone had a good chance to listen to the M8 and if so, what do you think?

Thanks to all
