Dynaudio Confidence 5 Owners


I have a chance to obtain a pair of Confidence 5's at a good price. I currently have a pair of Contour 3.3's that I like very much. What will the 5's do that the 3.3's won't . I'm looking for a similar sound, but more refined. More importantly do I have enough power to drive them. I am using a pair of Pass Labs Aleph 1.2's (200watts@ 8 ohms - 300 watts @ 4 ohms) that drive the 3.3's very nicely. I won't be able to audition before I buy (otherwise this post wouldn't be necessary) so any help would be greatly appreciated. Thanks.

I've owned the C5s and the pass 1.2s. The combination is not good. The C5s do sound great with a Pass X350 though. Its worth selling the 1.2s and the 3.3s, the c5s are in a whole different league.
The C5s were the best speakers I'd owned, up until the $4800 Dynaudio Special 25s came out. They handily beat the C5s ($10,000), and compete very strongly against the C3s ($8000, also now discontinued, but I still own them and always liked them better than the C5s). Both the C3s and the Spec 25 have better bass than the C5s.
Spectacular mid-range, well controlled, clear bass and great detail, crystal clear highs. The Esotar tweeter is simply amazing More expansive sounstage than the 3.3.
