What you say is true...I've had both high output and low output. But as
a
general rule, the low output moving coils have a lower effective
tip-mass
and therefore tend to sound smoother and track better.

Typical MC tip mass = 0.3 mg.

Shure MM tip mass = 0.040 - 0.139 mg

Besides, tip mass is not of the essence.

It's mostly irrelevant, that's for sure. Like most cartridge measurements,
it
tells one little about how the cartridge will actually perform.

Along with compliance, it tells you something about how well and with what
force the cartridge is likely to track. It tells you nothing about
cantilever performance or stylus impact on overall performance.

This is just another audiophile myth, perpetuated by people who lack the
proper background in mechanics and dynamic systems to understand how
these
things work.

The important parameter is stylus inertia, which is based on both mass
and
distance from the center of rotation.

Stylus assembly compliance is also a factor and there is no hard-and-fast
rule about that EITHER.

Agree, but they and tip mass work together to affect trackability, along
with cantilever design and damping and stylus design. These things must be
optimized as a system.
