Hi guys, sorry for the late reply.
Raindog031, a room like yours, i.e. of almost 27 square meters, will be adequately pressurized by speakers that are much larger than the C1s, e.g. Wilson Sophia, B&W 802D, Avantgarde Uno and DUO (u get the idea). All these speakers produce much more bass than the C1, so if you are unlike and your room is bass-hungry the C1s might get lost in it. Like you, I do not think that the C1s will totally get lost into your room. Probably even in the worths case a subwoofer, placed in the right place, will be able to solve this problem. (I have mentioned this just as a fictional scenario why you might not like the C1 and would want to re-sell them.)
Xti16, just because you did not heard other speaker that were more transparent than the C1 mk2 it does not mean that there aren't any. For example, all Focal Utopia monitor models (the Diablos probably have twice as much detail than the C1 mk2), B&W 805S/D, Wilson Duettes (and the list can go on and on..). I am not saying that when listening the previously mentioned speakers you hear details that you can not hear via the C1 mk1 or mk2 speakers, just that via the C1s those little things are lest obvious - one needs to pay much more attention to the music in order to become fully aware of those details. I have listen all models (mk1 and mk2) in the Confidence line often quite at lengths and they all have this characteristic. The strengths of all these Dyns is in the very natural and seductive midrange and powerful bass. Also, I would say that you are a bit biased here as it seems to me that you went directly from the C1 mk1 to the mk2 without much search (I apologize in advance if I am wrong.)
Regarding prices, I do not see the point you try to make - prices and or price differences are relevant in the present discussion. In the Netherlands quite a few dealers have both C1 models in stock and they will give a very generous discount for the mk1 plus full warranty but no discount for the mk2 models. (e.g. I have paid 4k euros for the C1 mk1 models I had in my room including the Dynaudio stand 4 stands and the speakers were basically new, i.e. no scratches and had full warranty. On the other hand a pair of C mk2s with stands cost 7K euros. A pre-own pair of C1 should cost here around 3k.)
Best wishes,
Paul
