KEF blades 2 or Dynaudio C4?


Hi guys, I am trying very soon the Luxman monos M900. I am wondering based on your experience and knowledge which speakers of these two would be a better match for them?
My room 18x12. High ceilings.
I prefer low volume music effortless neutral sound. I had owned KEF 3 and I liked them a lot.
But today I asked three dealers and I got mixed opinions. 
I do appreciate your time giving me your opinion. Kind regards.
Thank you.

Thank you. You are talking about big blades. I can't put th in my space. Blades 2 is what I am  thinking of. I was told ref 5 were basically the same but now you are making me realize it is not the case.
Thanks again.

I take this as a dealer pushing his product. 
Like most of your responses. 
Dealers will Always push what they carry! Some directly, some indirectly. I take what they say with a gigantic grain of salt. If I'm truly interested in a product I go listen and let my ears decide. 
I compared the Blade 2 with the Reference 5 and found that the Reference 5 worked better in my room.  The Blades do better away from walls but I was not able to position my speakers more than a foot and a half away from the back wall.  The tunable ports of the Reference 5 allowed me to get the sound right within the limitations of my room.  As with everything in this hobby, there are no absolutes and preferences are subjective.
