With 'only' 5 years delay I rediscovered this thread.. . I am using a JRDG Model 312 stereo amp. I have driven it with the following fully balanced pres, in ascending order of preference. . . from lowest to highest:
ARC Ref 3.
JRDG Capri.
JRDG Criterion.
312 has same input impedance of approx 40K Ohms as older 302. None of the pres I used exhibited impedance mismatch issues. But Capri and Criterion, with balanced output impedances of 80 and 60 Ohms respectively, yield IMO most preferrable results. G.
