I second Lgregoir's opinion on the YBA-SF combo. Generalising, I listened to Krell 80 (old) & 250 driving Guarneri -- they didn't seem to like each other. The YBA (passion integre, YBA 1, passion separates) matched very well. But then, so did the Pathos
I'm not sure the Concerto's need many watts -- current maybe (as Twylie implies).
Don't know the classe.
