preferance Pass Labs XP15 or Parasound JC3

I want to step up from my Nova Phonomena II. I have Pass Labs XP10 & 30.5. My first inclination was to stick with Pass Labs.
Looking for any advise for better sonic quality in the $3500 - $2500 price range. I have been told the Parasound is superior in sound. Advise?
Yeah, I would lean towards the Pass Labs because it should match better with your other Pass Labs stuff. Also, the XP15 is more adjustable than the JC3. Compare the 2 and see. Anyway, that's my take.
