Speaker recommendations 10 to 30k and no beryllium

Was searching myself in this price range and just placed an order for the Audiovector SR 6 ($25k). My room is much larger than yours and the Audiovector R 3 ($10k) may be sufficient. Definitely not for every taste and system but they are very fast, transparent and engaging. Can check out my comments here and I’ll update when I receive the speakers (probably several weeks away).

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.
