Pass X Series Preamps with JC-1 Monoblocks?

I will be using balanced XLR cables to run from the preamp to the JC-1's.

I guess I can now answer my own question.
I recently obtained a Pass Labs X-1 preamp to use with my Parasound Halo JC-1 monoblocks.
WOW, what a combo!
Combine the genius of John Curl and CTC Builders with the genius of Nelson Pass and Wayne Colburn, and you have a simply amazing combination!
These units match up extremely well, and have outstanding sonics and resolution together. I was quite simply amazed!
Any reservations or perceived weaknesses I had with the JC-1's are now gone! There are no weaknesses at all in the JC-1's sound when using them with the Pass X-1 preamp!
I have never heard such detail resolution, speed, dynamics, imaging, and utter transparency in my home or anywhere else, no joke!
