[Vintage-Audio] Re Shure M91ED and N91ED

[michael salmons]

Hi Duane,

According to the Shure website, the N91ED can track from .75 to 1.5 
grams. I have the M91ED/N91ED on my turntable (it shares time with an 
original Pickering V-15) and I always set it for 1.5 grams, which seems 
to be adequate for the old records I, too, am listening to!

Take care.

Michael
