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.

Not saying one or the other would be bad for low volume but if that is your norm there are better choices IMO. 
I liked my KEF reference 3 flat uncolored sound with sparkling cymbals I also own the LS50 wireless and I tend to enjoy KEF big sound. 
I know many good speakers out there.  I currently Dyna's special 40 and triangle deltas so I certainly can sense different sonic signatures plus AZ crescendos.
Regards 
I just wanted to note a couple of amusing coincidences:

> and a set of uni-q that were overdriven with a 1,000 watts of power.

First: I recently blew my KEF Ref3 uni-q drivers by overdriving them with Bel Canto Ref 1000s, in a mishap that involved switching between sources with vastly different gain levels on the preamp. They're at KEF in Marlborough NJ now getting repaired.

I don't think I told @audiotroy about that, so it must be a different victim he's talking about. But when I was thinking about buying them new I did listen to them at his shop. He might come off here as a self-absorbed know-it-all, but most of us come off worse online than we are in real life. And in real life, that fella is a prince. I enjoy his posts and appreciate his advice.

Second: I bought those used KEF Ref 3 speakers from the OP @mountainsong who is also, by the way, a prince of a fella.

Matthew it was great having you in my shop, and it was another client that blew up a set of Uni Q drivers on a set of Ref 5 that are now our display pair and appreciate you comments," And in real life, that fella is a prince. I enjoy his posts and appreciate his advice. "
It is nice to now that some people here who actually work with me and visit my store gets to understand that we really do know our stuff.

The Kef Reference line and the Blades are pretty amazing and lifelike sounding speakers if you drive them correctly.

Wcfeil, we really don't care that tatyana69 bought a pair of B&W 800d3 good for him if he liked them it is his money.
Do you think that a pair of KEF Blades or B&W 800D3 or Focal Sopra 3 or any super high end $20-35k set of loudspeaker is going to sound its best being driven by a: $3,000.00 integrated amp and $300 speaker cables? "

Is Audiotroy suggesting the dealer gave me an inappropriate demo? It seems so. Excuse me ... I am quite capable of listening to different speakers with different kit and making my conclusion that the Kef Blades are quite (very) inferior to the B&W800d3s (IMHO) for the very specific reasons I have given in my earlier post.
