Used Pre - Ayre, Pass or Para JC2?


Just wondering what your thoughts were on these three possibilities. One feature I'm pretty sure I'll need is bypass.

I have the Parasound P7 and really like it, but I've also heard the Ayre gear and have been enthralled. Balanced in/outs a must.

Thoughts?

I'm very pleased with the sound I get with my JC 2 BP.  For stereo, it takes output from an Ayer C-5xeMP or JC 3 phono stage and outputs to a pair of JC 1 amps.  For multichannel, the front LR from a Bryston SP3 is passed through the JC 2 to the JC 1s.
I really like the audio refinement pre5 by YBA. All analog with lots of inputs, imaging and presence. I have an extra one for sale. 
Ayre and Pass generally thought to be a level above the parasound product which provides good value for the $. Both the ayre  and pass products are excellent and if cost is an issue both make great integrated amps.
beyachad, I'm assuming you meant to say that you had a K-1x?  (Or was it upgraded to the 'evolution' [K-1xe]?)  I can't find a single instance online where someone has compared the K-1xe to the KX-5 Twenty.  I don't mean to hijack the op's thread, but it would be immensely helpful to hear even brief impressions of how they compare.  I'm looking to purchase a K-1xe with phono stage the next time I see one come up for sale, or a KX-5 Twenty.  Until recently I had the K-3x.
