Looking for a good full range floor stander


Hello all.  Making a good two way system for a 20 x 40x 12 high room budget 12k to 16 k.  Powered by a bryston 14b cubed amp.  Have a surround system with Golden ear ref and surrounds powered by parasound a21 for mains  and Carver cinema grand for surrounds. Like the GEs  The speakers I'm looking for will be for music only lots of jazz (female vocalist a fav), classical, classic rock and roll (70's and up).  I have heard good things about proac k6, Joseph audio, and a few others but am not within 4 hours of audition range.  Real interested in people in the know about the proac or suggestions.  Thanks in advance.

... Great speaker: footprint 12" x 12", 36" tall, pyramidial-shaped, full range 28hz - up, biwire-able; sometimes/rarely available on the vintage market and well worth searching out: late 1990s Gershman Avant Garde RX-20 (the earliest model), Avant Garde interations including newer models, up to the current model of the Avant Garde and the upscale version called the Grande Avant Garde (which is several inches taller due to a change in the base).
Heard both proac k3 and yg carmel 2 back to back.
no contest yg is a lot better but everything has to be on par
with this speakers; your equipment, cables even your source
recording. 

Proac on the other hand plays bad recording better making
it more listenable. It is coloured in an enjoyable way.

If you dont have the equipment for revealing speakers
like yg, magico, wilson etc, proac will do and its very good!
I have a wilson sasha 2 and hope to own proac k3 and
harbeth 40.2 to alternate with my wilson. Proac is a fantastic
speaker, they have better or more resolving mids than my
wilson, but they have cabinet colouration  that may bother 
others.
An almost 10,000 cubic foot room and people are recommending speakers with 5 inch woofers for a 600 wpc amplifier? I know everyone means well and it depends entirely on the desires of the OP but if I had a room like that I would deeply appreciate that a dealer took the time and offered advice. Furthermore, how is it biased to recommend products in equal measure alongside products said dealer does not carry?
