Speaker recommendations 10 to 30k and no beryllium

Vandersteen Quatros with Carbon tweeters. 

OP:

If you are in Ontario you can audition the Joseph Perspectives at Executive Stereo. 
And also at Fairview Hi Fi.

You definitely have to audition the ProAc K6.  I have had mine for 4 years (bird's eye grey, high gloss and no bullet holes) and they are absolutely superb.  I have the same size room as you.  I'm a member of a local audio club and just about every speaker imaginable is represented in our group including top end Focal, B&W, Vivids, Maggies, JBL, Dynaudio and DALI's.  Our members keep coming back to the K6's for best sound.  They are indifferent as to SS or tubes.  I have the Octave MRE 220's and the Jubilee Preamp.  They love all types of music.  I noticed that ProAc released an special edition K6.  Enjoy the hunt!

@prof wow! Amazing tip... going to definitely head over, thanks.

There are 3 KEF Blade 2 on sale on Audiogon at the moment from 13K to 18K. I have no space for them today but the bad voice in my head says to buy 1 of these listings and keep it in storage. The good voice in my head tells me to to have patience and buy later when I have the space.
