Best Tube Preamp for JC-1 Monoblocks?


Hello all,
I have become interested in tube preamps to try out with my Parasound Halo JC-1 monoblock amps.
Based on current or previous owners experiences with using tube preamps with the JC-1's, which tube preamps seem to match up the very best with the JC-1's without giving up much, if any, the dynamics, top-end extension, and bass qualities of solid-state preamps?
Thanks for your responses in advance.

Lanny,

Get yourself a 30-day eval unit of the DeHavilland UltraVerve. You just may end up keeping it like I did. If it doesn't work out, ship it back. One caveat, it does not support balanced XLR connections.
The JC-1 will sound better driven in balanced configuration so look for a balanced preamp.
Thanks Mark and Bob, for your responses.
OK guys, what tube preamp with balanced outputs would you most recommend for the JC-1's, based on personal experiences?
Thanks!
One more thing,
Is it really true that the JC-1's actually prefer a solid state preamp over a tubed one for best sound and matching?
I have heard or read that somewhere, or from someone before.
