Jeff Rowland Capri VS Capri S2

Hi, I had both same time, side by side. The original unit has more organic sounding that I spent hours and hours without getting tired of- just listen and enjoy music But side by side, the S2 is a better unit; more refine and define across the sound spectrum. Every notes, every plucks on every musical instruments and vocals are just simply better. If I could exaggerate it, think, the original unit as a great awesome cassette player and the S2 as a DVD player when they first came out. The S2 just opens up and has more air and clarity which slightly goes out of my comfort but in the end it’s a better unit and that’s what I upgraded from my beloved Capri original. Yes, the price of S2 on used market is nearly double the Capri original, and the improvement, IN MY SYSTEM, is about a quarter but surely noticeable.
Dont get me wrong, you will still love the original immensely, but I kept the S2 because, fortunate enough, I can afford to keep it today. I prob would not keep the S2 if this was 10 years ago.
I hope this helps

Thank you for your detailed reply. What kind of power amplifire you were using with Capri?
I purchased JRDG 102 about two weeks ago, no regrets.

To OP, At the beginning, I too had JRDG 102 amp to mate with Capri original and many small bookshelves in a small room- good result(very) sweet sounding and ease to the eyes. Good combo. 
I now have VTL ST-150 tube amp to drive Sonus Faber Cremonas floorstandings. Best

Do you use power conditioners for your pre and power? 

I like using Richard Gray Power conditioner. It has the warmth and mellow that I like. I did have everything hooked up to Richard Gray including my integrated amp, but my new tube amp now goes direct to wall outlet instead of Richard Gray.
Cheers
