I've no experience of the combination but as you've had no response figured I'd throw you my 2 cents fwiw.
Clearly can't comment on the synergy between Gryphon and SF but I'd think the Diablo is in the right ballpark as intergrated amps go. A guy I know used to run a Dartzeel intergrated with his Amatis A's and loved the combo. Only reason he changed the speakers was a house move and a smaller listening space (he downsized to Guaneri).
