My question is why Moving Coils should be thought to be

Trackability should be better on a MM, as should record
wear due to lower tracking weights.


I am surprised there has been so little development of
cartridges beyond the two basic magnetic types and good
old ceramic. What about an optical cartridge for example?

Are you talking about bouncing a laser off the record
groove? It was a failu it was too expensive and
worked worse than traditional methods as it was best at
reading the crud in the groove instead of just pushing it
aside.

I heard and saw an example of that failure producing music at HE2005 about a
year ago. AFAIK its still on the market. If you have the money - they have
the product!
