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

In a room of that size you do not want too much bass. Something like a Harbeth M30.1 is the maximum of what a room like that can handle before you will suffer from pretty bad room modes. Even so, I would investigate dsp room equalization.

@willemj you're right about too much bass and room modes, however room treatment will be far better than DSP EQ. I prefer the least amount in the signal path as possible.

@vermeer my room is 140 sq ft, or 1375 cu ft. (11 x 12.5 x 10) -- a cube is less than ideal, however, listening near-field is actually sublime. Take a look at the golden ratio on Cardas Audio: http://www.cardas.com/room_setup_near_field.php

Here is the room setup guide: http://www.cardas.com/room_setup_main.php

If you can grab yourself a measurement mic, you can run REW yourself to figure out where you start before you invest a penny in equipment/speakers.

Enjoy!

@willemj : totally agree with the dsp ... I've played a bit and it really seems to be the way to go! and yes: speakers cannot be too big and I'm affraid the Sopra 2 may be a bit too much for the room ...

@vermeer Glad you also like the Focal house sound. I know Sopra 2 is not going to get you to the level of Magico Q, but it should be a good match for your electronics. I went through a different path of upgrade. I upgraded my speakers first and found the deficiency of my amp; then I upgraded my amp. BTW, my room size is 20x14x10 (LWH).
