I listened to the GRAAF with the Sonus Faber Amati Hommage and the Cremona. Both fantastic matches!
I listen to a gm200 + 13.5b with SF Cremonas and they sound beautiful.
I also enjoy the gm200 with SF Guarneri's. The cremonas have more bass and have become my preferred match for the gm200.
I tryed my amati's with the gm200 but i prefer a pair of monoblocks ARC 210 for these speakers.
Gm200 is exquisite with the cremonas.
