I came across this thread because I have been interested in the EAR 324 for use with a myriad of vintage MM and MI cartridges that I want to audition. The front panel controls for capacitance and resistive loading would be very useful in that regard. In reviewing published reviews of the 324, I came across two "disturbing" comments: (1) John Atkinson measured rather poor overload characteristics for the inputs at frequencies below 100Hz (distortion went sky high at inputs above 5mV, which would easily be reached by any MM cartridge), and he suggested that an MM cartridge might well overload the stage and induce such distortion, and (2) after praising his demo unit, Ken Kessler let it drop at the end of his review that he thought the 324 was a tad "grainy". Have any of you guys experienced either phenomenon, or do you know whether or how TdP addressed the overload "problem"? Thanks.
By the way, a 7DJ8 is naught but a 6DJ8/6922 with a different filament voltage requirement (7V instead of 6V), as far as I know.
