I've heard the Cremonas on a couple SS amps of 200+ wpc but never on tubes. I bought a pr of Dodd monos from a fella who said he had Cremonas, or heard them with the 120wpc Dodds... and liked them a lot.
I'd say the Cremonas will like tubes. I wonder though about 70wpc or if they have a 4 ohm tap out of the amp. If so then it's likely going to be a matter of preffs as to the listening levels you can achieve using the CJ amp.
I've little doubt the CJ amp will drive the SF speakers, and I doubt seriously anyone can advise you as to exactly how well.
there is always bi amping, and/or subs... if things don't turn out exceptionally well for your situation.
They'll work... I'm sure... how well is another story.
Sorry I'm not more help.
