Never heard the DM series. My local Dyn dealer had the audience line but has been replaced with the Excite line. I was recently invited to a Naim - Dynaudio - Octive demo. While we listened to the Dyn Consequeces driven by Octive Jubilees the dealer stopped and had a Naim super Nait driving the Excite X 12's in the same room and fired it up. Holy cow - the Naim/X12 system sounded really great for being in a large room. Dyns are great speakers but do love current. So if there is a downside to Dyns that would be it. So as another option consider the Excite line.
I own C1's and can't think of anything bad to say about the sound. Everyone has their own opinion of what sound they want/expect from a system. If at all possible see if you can do an in-home demo and that way you will know for sure.
