What are you using to verify inductance and resistance repeatedly?
I've measured, using state of the art equipoment (with AC test signal, the only way to do it right) 30% differences in impedance with some brands. Yes, "mass produced" ones, if you can call the bigger premium MC makers "mass produced".
A few manufacturers are quite consistent, and very consistent in sound. And with many manufacturers, I've never heard 2 sound close to identical, tested one right after the other. Fleib, how are you measuring compliance?
