Grand Pianos paired with Classe/Theta electronics?

A recent move to a house with a smaller listening/ viewing room has compelled me to sell my Legacy Audio Signature III's (with matching center and rears) and replace them with another speaker system. I'm using a Theta Casa Nova processor, and a Classe Audio CAV-180 for power. This combination sounds fantastic to my ear, but the Legacy's are simply too big for my new room.

During my recent demo spree to find a new speaker system, a couple of speakers have struck me as excellent, particularly for the money. First is the Sonus Faber Grand Piano Home, which Sonus will soon phase out, but I still believe is a great speaker, and it's available for a fairly drastic discount at $2,500 for the pair, brand spanking new. The other is the Paradigm Reference Studio/100, which ends up being about the same price.

I have a few questions for anybody that can help:
1. There are so many great reviews about the Studio/100 speaker system, but I don't see many on the Grand Pianos. Am I crazy or are the Grand Pianos a fantastic speaker, but too pricey if you have to pay the $4k list price? If they listed for $2,500 a pair, wouldn't they show up on a lot of experts' recommended speaker lists (as the Studio/100's do)?

2. Are the Grand Pianos (along with the matching Solo center and Wall rears) a good/bad/ugly fit for the electronics that I've mentioned? How about the Stuiod/100's?

3. Can anyone comment on the comparative strengths and weaknesses of the Grand Piano vs. the Studio/100, for both (jazz/blues/acoustic guitar) music and home theater?

4. Any suggestions for alternative speakers to demo, given my electronics and a price range for mains ranging to around $3k? I've thought of looking at the B&W line but there are no local dealers.

Thanks, and sorry to ramble. If the length of my post has offended you, please accept my apology and move on.
