Pass Labs XA30.8 for Dynaudio C1 Platinum

I haven't had the privilege to listen to any Pass labs equipment, but I've been eyeing the possibility of trying out the "lower" powered class A amp(s) and possibility even a line preamplifier from them. My current amp is an Anthem Statement P2 with gobs of power, so I'm not sure what to expect with an XA30.8 that's conservatively rated around 60 watts in 4 ohm loads. Anyone have first hand knowledge with any of the class A amps in regards to powering "not so efficient" loudspeakers care to chime in? Thanks!
