If you are considering JC-1's then I'd recommend the JC-2 preamp for obvious reasons.
The JC-2 is an excellent performer, and the JC-1's are truly phenomenal in my experience.
I like Ayre gear too so that is another brand I would suggest you listen to.
I've owned an LS-26 and while it was very good, it does not have the dynamics of a good SS preamp.
I have no experience with the Calypso but others seem to love it.
Good luck with your system choices, you are considering some good options so far IMO.
