Searching for the most "accurate" speaker (below 15K)

At under 15k the pair why not go for the best (IMO) and pop for a pair of Magnepan 20.7 's.  Pretty hard to beat for the money if you have the room.

I think OP has a small room (around 200 square feet). I used to own Maggie’s and loved them.  The space required for Maggies to fully perform might be a deal breaker here. 

Thiel CS 2.4 or CS 2.7- natural, fast, accurate.
Happy Listening!

These days have been hectic and I was not able to come back to discussion before ...

@marktomaras : yes, I know Imacustica (who doesn´t in Portugal? ;)). I must confess that Wilson is not exactly my sound ... and currently they have no opportunities. They have, however a pair of Martin Logan Summit X which are going to be sold with a good discount since that line has been discontinued. I'm not sure however if they will be a good fit for a small room ... And I also don't know how my amplifier will handle them ...

@david_ten : it is a living room in a restored 100 years old building. It is a suspended wood floor, so I've playing with isolation solutions to decouple the speakers from the floor ...

From my perspective I don't feel the discussion has been hijacked by a dealer. Actually there was a very informative post from @audiotroy which I felt was quite honest (btw, it was removed not longer after it was posted). As long as properly identified (and this is the case), I have no problems at all in having dealers taking part of the discussion. We all have biases, not only the dealers ...

Vermeer, thanks for the kind words and support.

Your room is small but it is not that small. As long as you look at direct radiating loudspeakers with bass in the 40-30hz range you will be fine.

Also depending on electronics you can avail yourself with units from Micromega M100 or M150 hat sound fantastic on the Personas and also have room correction. 

Our smaller playback room is 18 feet long by 14 wide and the Persona 3F sound fantastic in that size room.
