which speakers, under $2K used?

I'd like to upgrade my current speakers, a pair of Quad 11L mini-monitors. I'm happy with them, but I think I can get even higher performance. I'm using a Unico amp, MMF-5 turntable with Monolithic amp, and a Sony SCD-777. I'd like to keep the price under $2K and here's what I've narrowed my selections down to:

Joseph Audio RM22si
Joseph Audio RM7si
Spendor 3/1P
Sonus Faber Concerto Home
Sonus Faber Signum.

My room is medium-small and I play varied music (from rock to classical). Qualities in music that's the most important to me are: a wide soundstage, a sweet midrange, and a nice holographic sound. Your thoughts?
