Would a Lamm ll2.1 deluxe slay a Parasound JC2?

Hi. 

I have been thinking of adding a tube preamp to my chain to get a little more body and feel to the music. 

I currently have a Parasound JC2 which is detailed and dynamic. Very good really. But I may have trade and cash opportunity for a Lamm ll2.1 deluxe. It would be going into a new Bryston Cubed power amp. 

I havent heard a Lamm. Would it be a much better piece? Worthy of trying to work a deal?
