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

If you choose to consider Class D amps, do visit the Cullen Circuits website and peruse his "Wyred for Sound" monoblocks. I recently bought a pair of the "Ice Cube SX-1000"s and am very impressed. 1000W/channel into 4 ohms, well-built and quite attractive in an understated way. They are dead quiet in balanced mode and sound terrific. At $1199 each they are a huge bargain relative to other high end amplification.
i have had the jc1 , ml335 , pass x350 , krell 300cx but now i keeping the ml23.5 . Thanks

What has been your experience with the past amps you have owned and what do you like about the Ml23.5? Thanks for the input.
