Sonus Faber Grand Piano Homes - What next??

Looking to upgrade speakers from the GP Homes. The new speakers would be used in a combination two and five channel system. The room is 17 x 13 with 9 foot ceilings. Associated equipment:

Classe SSP 60 processor
Sunfire Signature Grand amp
Modified Pioneer DVD player
Velodyne sub
MAS cables

Willing to spend around 3K used. Matching center will be bought seperately. Here are some speakers I am interested in:

Green Mountain Audio Callisto
Gallo Reference III's
Dali
Tyler Acoustics
Hyperion Audio
Shahinian Obelisk
Gradient Revolution

Stand mounted or floorstander doesn't matter. I am looking for a speaker that combines the best of electrostats ( which I have owned) with a conventional box speaker. Music choices are jazz and vocalists.

All suggestions are welcome.
