Hi , I have 2 Graaf Gm 20 used in biamp ( two stero amp one for the bass and one for the tweeter ) with a Graaf 13,5 bII and a Graaf Gm 70 phone stage.
I owned first only one Gm 20 with the same pre and i was absolutely wondered for the fastastc sound. With two Gm 20 the sound became amazing: detailed, terrific. Try it if you can, buy one and keep it .
