I have had the Dynaudio C1's for the past two and a half years and really love them. Previously I had the Contour S3.4's and enjoyed them very much which was my impetus for upgrading - I wanted more of the same, which I feel I got in the C1's. I drove the S3.4's and the C1's with a Krell 400xi, which was an excellent value for the price. I felt it hands-down beat the McIntosh MA6900 driving these particular speakers and I demoed both amps side-by-side. It was no contest.
Recently, I upgraded to a setup similar to Xti16's with the Octave V70SE and the combo is everything he says it is - I couldn't be happier! If you're interested in Dynaudio, check out the "Dynaudio Owner's Thread" on avsforums.com for a ton of information on those speakers (just Bing/Google it). A few others there have the Octave/Dynaudio combo and love it.
OP, the speakers you mention are all great but system synergy (with amp and source) are key. I'm sure the McIntosh amp sounds great with others (I've seen them paired with B&W a lot). You probably just want an answer, but everyone's ears and taste is different. If possible, you should demo them all (ask the dealer to swap the amps, so you can try different ones) to really find out what sounds good to *you* and then you won't be disappointed!
