The specifications that came with my Sennheiser K6 ME67 say that the
sensitivity is rated at 35 mV/Pa (rather than 50 mV/Pa).  I've had my mic
for a while, maybe there's a new model out or something?  Or just the wrong
specifications being peddled?  That's a great idea to compare MKH70 with
ME67 and if Greg Clark or anyone else can do a comparison sometime, that
would be fascinating to hear!
