Sonus Fabers and tube amps

Will Sonus Fabers sound good with a tube amp? Are they too soft which will add to the softness of tubes?

I have SF Grand Piano's (not the new version). I have tried the following tube amps: Mesa Baron and VAC Avatar SE. They both sound great and I highly recommend good tube amps for these speakers.

Hi Mozart,

Absolutely! I've listened to Guaneris with quicksilver amps and the combination was just gorgeous.
