Merlin VSM MXr vs Thiel 2.4 vs Dynaudio C1

Hi, I got a lot of good recommendations from viewers of my other thread "Best speaker under $3K". I wonder if I stretch my budget to around $4K- used, what would be the choice?

A few people mentioned the Dynaudio Confidence C1, Merlin, Thiel, etc. Anyone have experience with these fine speakers? How would you differ them?

FYI, I listen to a variety of musics - orchestra, chamber, vocals(female and male), jazz, pop songs,etc and prefer natural, accurate, musical sound with smooth treble and good bass as well as excellent sound stage and imaging.

I had experience listening the Vandersteen 5A and was very impressed by the dynamics and details it rendered. But it's way beyond my reach.

Realistically, I would consider the few candidates mentioned above and maybe the Reference 3A Veneer. My listening room is about 13 x 15 x 9.

Thanks for your help.
