Pass amps

Has anyone tried this brand with Merlin speaker's?
I haven't actually heard the combination, so this is only speculation: I think the Pass Alephs might work well with the Merlins, but I don't think the X series would be a very good choice in this case. My experience suggests that the Merlins prefer an amplifier with a fairly high output impedance.
I am running a pair of Merlin TSM- MM speakers with Pass Aleph 1.2 amps and am very impressed with the sound. I originally was using a Naim integrated to drive them and thought the sound was pretty good but when I moved them to the main room the speakers really came to life. The Pass amps made a huge difference.
