NAD C542 vs Audio refinement Alpha complete CDP?

I have been looking for a new budget CDP and was wondering if any of you have compared these 2 players? I like listening at moderate to higher volume levels. I listen to all types of music Blues jazz rock. This is for a second 2 CH system. It will be accompanyed by a NAD pre and Adcom gf555 amp, Paradigm Espirt bipolar speakers. Room size 15"x10" 8" ceilings. Also other CDP's in 300 to 550 price range???
