Dynaudio Contour S5.4 or Confidence C2


I have always been a great fan of the Dynaudio speakers, went from Contour 1.8Mkii to Contour 3.3. I am thinking to upgrade again to S5.4, however confidence C2 is also within my consideration. Any advice on this? Has anyone compared the 2 and can comment on whether the improvement justifies the price difference (about $2k for used pairs).
I am using sometimes Sonic Frontiers Power 3 monoblocks and sometimes McIntosh 501 pair to drive the speakers.

From what I've seen in the classifieds, used 5.4's have been selling for around $5K... and used C2's are only another $1,000 or so. Go with the C2's now and save up for C4's!
neither- save up for C4s if you want the floorstander. why buy a 2.5 way speaker.
Thanks for the great response so far. My concern with the C4 is placement. My little audio nirvana is really quite little, measuring only 13'x15' with relatively low ceiling. The C4 really will dwarf everything in the room with its height reaching almost 6'. Is that a valid concern?
I have my C4's in a well treated 15' x 21' room. I don't think a 13' x 15' room is large enough to let the C4's breath, as they really need to be pulled away from surrounding walls to sound their best. If you want to stay with Dynaudio I'd look at C2's or C1's with a nice subwoofer. Both of your amps would work fine either way.
Pdreher is right regarding the C4's. You will never really hear the full potential of the C4's with your room. Have you demoed the C1's with a sub? You may be surprised.
