As a C1 owner too I'm considering upgrading to the C2's for some more of that Dyn bass. Currently I have a Rel B3 and although it integrates well it just isn't that Dyn bass. I would say when I demoed the C2's in my home I got a lot more bass than the C1's but not quite enough. I think my problem is my room though. I seem to get great bass everywhere but the sweet spot. I do have to listen nearfield. Placing the sub in a corner really helped. Dyn's need room to sound their best. The C2's sound much better at my dealer than at my home partially due to his room size and he has better electronics. I have a Bryston B100 and your B4 squared should be plenty of good power. In my situation I'm not sure if I can live with them here without the sub (but the C2's sure do look better). In fact to make the C2's sound as good as the c1's for mid's and high end in my room I had to get them pretty close to the back wall and not toe them in as much.
I will admit I have never heard the contour line because once I heard the C1's I stopped my speaker shopping and had to have them. At that time my dealer did not have the C2's or C4's to compare but even so the C1's were way over my budget. I still haven't recovered from that yet either. To me the confidence line is fantastic in transparency imaging and detail.
Were you able to compare the 5.4's to C1's or the C2's at your dealer since he doesn't have both?
