Have ya tried it? I never said it was ideal. You in fact quoted the part where I said “not as hot as you’d like”. I think you’re overstating a bit, though. People have done it and are doing it and will do it. Yes a transformer is better. Actually a real preamp is even betterer. Not plugging your mic into a damn guitar amp would probably give much better results. But the actual problem with the OP was that one of the wires wasn’t connected. Connect that wire and it “works”.Without a matching transformer, a low z mic's signal would be lower than the noise from all that gain.
