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 owned the Ayre KX-1 and KX-5 (Twenty) for a number of years. Both are terrific pre-amps however only the KX-5 does bypass and it does it very well as it adjusts the volume automatically and you can adjust the gain settings. The KX-5 also has balanced in and outs.

I had the Paramount JC2 a couple of years ago. Initially I thought it was good, but I quickly sold it. In my system it didn't provide details and open up the soundstage like I expected. I was going from a DAC straight into the amp.
