Full Range Speaker $15-$20000 Range?

My system consists of Thor Audio tubed 150 watt monoblocks,
Thor linestage, Thor phono stage & a Thor Dac(ALL Tubes)
with a Cary 306/200 which I use as a transport, Scoutmaster
by VPI table and a Clearaudio Discovery cartridge, and finally a pair of Quad 988;s, loudspeaker with a Audio Physics Minos Subwoofer. My room is 20 X 20 with 12 foot ceilings. The room has been completely completely treated by Mike Kochman of Echo Busters who has done a
wonderful job and I can give my highest recommendation.
The problem is that the sppeaker lacks in dynamics and soundstage. The sound is great with small scale chamber music, solo voices, and solo piano, but it cannot reproduce
an illusion of an entire orchestra and it softens dynamic contrasts, for example the tambourines in Capricio Italien
by Tchaikovsky's are softened. In a non elecrtostatic
speaker the tambourines snap like they do in real life.
I would also like a speaker that does not require a sub. Without the sub on my system the lows are very disappointing. I also need a fairly efficient speaker, because 150 watt a side won't drive a Magnepan and many others. I listen exclusively to 2 channel music, mostly classical, jazz, and classic rock. Does anybody have any personal experience with any speakers that I can audition?
