@czarivey , ''cartridges with sufficient output....are plenty-plenty''.
The moving parts by MC carts are stylus, cantilever and coils.
Reducing the moving mass by styli and cantilevers (tubed- boron,
sapphire or beryllium) would make not much sense if the coils
use so much wire that the mentioned reduction is undone.
Designs by which iron core is used to increase the output have
their own problems so coreless coils deliver those small outputs.
Ortofon, for example, uses just one layer of wire with about 0,2
mV output. But Ortofon also produces matching SUT's .
''Old'' and new Ikeda's have also < 0,2 mV. You can at least
assume that those designers which prefer low output have
good reasons to do so.
