alright, so I borrowed a set of MG300s from my friend Andrew and these things smoke with the MP-2->Mod SBM-1.....recorded a local rock band tonight (Melbourne) at a shitty venue (the Brewery) that had way too much bass, and the tape is incredible.....these mics have a sense of clarity that I have not heard from the 391s. Not knocking the 391s...more a compliment to the gefells!
More listening necessary....will post as I do!
