Cartridge questions...

OK, so I saw the classified ad that "Shonver" put up for the cartridges and had a look at the Ortofon Rondo Blue MC, specifically because I have a 2M Red currently.
I did a comparison between the two and apart from the obvious, what makes MC so much better than MM?


Rondo Blue
Output voltage at 1000 Hz, 5cm/sec. 500 ?V
Channel balance at 1 kHz 1,5 dB
Channel separation at 1 kHz 25 dB
Channel separation at 15 kHz 18 dB
Frequency range at - 3dB 20-35.000 Hz
Frequency response FIM distortion at recommended 20-20.000 Hz ?1,5 dB
Tracking ability at 315Hz at recommended tracking force 85 ?m
Compliance, dynamic, lateral 15 ?m/mN
Stylus type Nude FG70, Al. cantilever
Stylus tip radius r/R 5/70 ?m
Tracking force range 2-2,5 g (20-25 mN)
Tracking force, recommended 2,3 g (23 mN)
Tracking angle 20?

2M Red

Compliance, dynamic, lateral 20 ?m/mN
Stylus type Elliptical
Stylus tip radius r/R 8/18 ?m
