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!
