Jay as far as the 2M Bronze, it has 5.5mv output and a nude fine line stylus.
The Black and the Bronze have the same magnet and coils the only difference is the Black has a Shibata stylus and I think sounds a little more full bodied and more forgiving of surface noise.
I use a Manley Chinook phonostage.
I set it at 40db of gain for the 2M's.
