Risky Pass purchase...?

I've recently purchased a Pass XP-20 to replace my Roksan Platinum pre but I haven't even heard the XP-20! As the deal was so good & my curiosity so great I had to get it.
I'm a bit concerned about compatibility with my Roksan Platinum dual mono power...

Can any other owners reassure me of its performance?! Does it live up to all the favourable reviews?
