Levinson, Pass labs or Parasound?


Driving a pair of Soundlab A-1's which would be a better bet. All three amps below are approximately the same cost on the used market. The parasound mono's have had exceptional reviews when specifically mated with the A-1's but have no real way of demoing them. Anyone have experience with any of the following amps?

Parasound JC-1's

Pass Labs X-350

Mark Levinson NO:335

Thanks for your input
