With no direspect to you, Stickmen451, I won't to drive my 3.6's with the amps you asked about. I would recommend you audition a Pass Labs X-350.5, or if you can swing it in your budget a pair of Pass Labs XA-60.5's. I drive my 20's with a pair of 60.5's, the best the Maggies have ever sounded. I have heard the JC-1's with both 3.6's and 20's and found them OK, but no were as good as either the 350.5 or 60.5's. I never have been a Krell fan historically, they just don't float my sonic boat.
I also would recommend you take a look at a pair of Myesound stands for the 3.6's, they will effect the performance as much as what amp you use with them.
