I have to disagree with Michael about a newbie starting off with a tube amp
(The exception is if a GOOD dealer is locally available to work with a new to tubes customer)
A tube amp is just a big deal. True it is the best to 'really' get tube sound, but it is a lot of 'tubeyness' for a new to tubes person to start with.
On the other hand the OP has a great SS preamp already.
The OP idea of using both a tube and the Parasound JC2 is decent.
I have several preamps and the main Bryston BP-26 has both an Audio Research SP-15 I use only for it'e tubed phono section (going into the Bryston) and also a VAC Standard (4 tubes) preamp I use as a 'tube buffer' from my DAC to the Bryston BP-26 via the VAC Standard.
I like the result very much, and get to keep three great preamps around in use.
