Add JBL and Polk (both were very popular with my Hard Rock friends in the 70's and 80's) to your list to audition. JBL is reviving some of their classic models, with upgrades, from the 70's, and if they sound like I remember.....a can't miss. You might want to audition the Monitor line, both tower and "book shelf" from England. My main system is built around vintage KRIX Euphonix (I auditioned with Tommy Bolin's Wild Dogs) floor standing tower speakers, but in a MUCH larger space than your room. My upstairs systems are in a similar sized room to yours, with a dedicated mono and dedicated stereo. One uses a new to me, pair of Totem Arros (rear port and not thumping bass), that is the mono, mostly jazz and classical. I've been aware of the Totems for a number of years, and the stars (and bank balance) finally aligned. The 2 channel system, mostly rock, big band, jazz,experimental, avant-garde, and fusion uses a pair of stand mounted ELAC Debut 2.0 (front ported, and a nice bass delivery for their size, but they are in a market segment that has exploded with excellent new speakers--- check out A British Audiophile on you tube, similar listening room, and he does a bunch of physically smaller high quality speaker reviews, and unlike some, he reviews instead of shills). BTW I listen to CD, tape and vinyl play back, and that's what I use to audition.
Auditioning is the only real indicator.... please yourself first!
