Need a system for Chamber music--ideas?

My current system does well with larger scale works - orchestral, choral, etc, and also with solo works. Where it struggles is with chamber music. String quartets in partiuclar are a problem. It is essentially impossible to distinguish between the 1st and 2nd violins. Maggies are always going to struggle with this due to the side by side arrangement of the ribbon tweeters with the midrange panels. I could go two ways.
1. A completely distinct system in another room, using monitors. If I go this way, I might like a reccomendation on a tube integrated to pair with the speakers, and the speakers should be able to go close to the wall for flexibility. A concern here would be decent reproduction of piano-- don't want to create a new problem in listening to piano trios etc. I'd probably like to stay under 7K for the amp and speakers new or used.
2. A set of floor standing speakers or monitors to swing into place in my current system for listening to chamber. They should be below 80lbs each to facilitate moving. The maggies are going to stay for large scale works. I'll keep the current system in place, so the floor standers should work well (at least initialy) with high powered SS amps like my Cary 500.1's. Again, 7K-10K, new or used. Accurate timber and coherence, especially with violins, are imperitive. It will not be necessary for them to play above 90dB. Also, the speakers must be able to throw a convincing stage for string quartets. Speaker placement will be along a short wall in a 15.5 x 19 x 8' room. I do like the sound of Sonus Fabers. Might be open to Dali's. Wilsons in this price range are out, and I don't like Dynaudio, Theil, Aerial 7T's. Haven't heard Ref 3A Grand Veenas or Merlins but you hear good things about them. I will not buy speakers unheard, so I'm wanting to generate a list of speakers to audition. When I bought my maggies it was a 2 year process. Your thoughts please?
