Do you have run them non-stop? Only if you are impatient like me ;) The distributor told me that. My Dyn C1 sounded great out of the box but between 100 - 200 hrs they sounded horrible. Honky - dull even a little smeared. That lasted for about 50 hrs before they started to come back (I wasn't happy with the finish on my first pair and by the time they were broken in my replacement arrived - Now to do it all over again). When I upgraded to the C1 signatures I switched to my son's system (not as resolving) so I didn't really hear that 'horrible' time.
That being said I haven't heard of any other speaker manufacturer that goes through that. The Originals really took between 350 - 400 hrs to finally sound great. The distributor also mentioned the C1's take the longest of the entire line up. As for the signature/MKII I e-mailed a couple of other owners and they said at about 25 hrs they went downhill and about 50 hrs they were great.
That is my experience with new C1 speakers.
