Jeff Rowland Capri VS Capri S2

I have been offered a JRDG Capri, with a phono stage, at a great price, I understand there is a newer version of that preamp called Capri S2. I was wondering if anyone here has had the opp to use both in their system and their thoughts and impressions of these two. The Capri S2, retails for almost double the price of the original Capri. 

Many Thanks
