Dynaudio C1 or S25?

Have you had a chance to audition these two models side by side in the same system? I'm considering upgrading my Dyn S1.4s to one of these two. I've heard the Special 25s which I love. I haven't heard the C1s yet. I like the more conventional looks of the S25s better. Did the C1 do anything better than the S25s in your opinion?

Based on my experience, I wouldn't recommend running Dynaudio products (especially the S25s) with the tube amps you mentioned. I tried the S25s with tube amps of similar power/current and they were unable to make the S25s sound excellent. Switched to the Sim W5 and a Musical Fidelity offering (forget which one) and the magic was back.

I did audition both speakers with SIM and audio research power. The audio research was the VT100MkIII. It sounded noticibly better. The C1's were the favorite. The audition was over four hours and I think my mind was starting to play tricks on me. I remember the S25's being worth another listen. I want to try them both at home. I also want to hear the new Linn 200w/chakra. My budget for the amp is ~$3K. Upgrades would continue through the year for preamp. I will use my Linn classik for now.

Dynaudio drivers require power. Using less than adequate power will produce boomy bass.
I believe the S25 are harder to drive than the C1.

A poster named Simple did a review of the C1 a while back where he compared the two. He preferred the C1, but it could be just a case of "new-speaker-titus". Link is below. Technically, the C1 is a better speaker, being time-aligned and all, but it all depends on tastes and your listening room.
