Preamps: Parsound JC2 ss vs Modwright LS100 tube

Thinking about trying out the brand new Modwright LS100 preamp using 6SN7 driver and 5AR4 rectifier tubes (also 12AU7 and 12AX7 tubes in the phono section) and wondering what others with more experience think about how it would compare to my solid state Parasound Halo JC2 preamp.

This would be my first tubed equipment purchase. Would you expect a very different sound to the JC2? Would it be a sideways move with just a different flavor? Any thoughts/impressions/comments would be welcome.

Associated equipment is the Parasound Halo A21 power amp, sources are Arcam CD92 and VPI Scout TT. The speaker purchase I am planning is Acoustic Zen Adagio floorstanders.
I have not heard the JC2 preamp, but I do use the Halo A21 with the Modwright LS100, and I could not recommend the combination any more highly. I know the JC2 is very quiet, but for me (and many others out there) the combination of a tube preamp and solid state power amp gives you very lifelike reproduction that solid state alone just doesn't provide, along with real speed and power.
Please do try the LS100 if you have a chance to do so...I couldn't be happier with my humble system. (I have no affiliation whatsoever with Modwright.)
Another Tube preamp that works very well with Halo Parasound is the Lector ZOE.. I have one with two JC1's and it's a fantastic combo.
