MKH vs Telinga EM23 noise

["scottsherk27" scottsherk27]

I recently began experimenting with a Sennheiser MKH 30-40 M/S rig.
I've been running this through the Rolls PB224 and then into a Sony
RH10 Hi-MD.  I seem to be experiencing too much high-end noise,
especially compared to what I'm used to with my pair of Telinga
EM23's.  I've posted some crude test recording on my site.  I`ve
recorded the same clock with both the EM23's and the MKH's with gain
of 22 and 28 on the RH10.  I only normalized the files.  I would
appreciate an assessment of this high-end noise.  Here is the page:
