Sonus Faber Grand Pianos vs. Thiel 1.6's

I have demoed both of these speakers, with the same music. The sound stage the the 1.6's represent is amazing, as is the clarity of the overall sound. The Grand Piano's have great sound as well, but a bit warmer than the Thiels. I like the sound each speaker gives off, thus making this difficult.

Can anyone give me some input in making this tough decision??

Thanks
