Who needs a MM cartridge type when we have MC?

Dear friends: who really needs an MM type phono cartridge?, well I will try to share/explain with you what are my experiences about and I hope too that many of you could enrich the topic/subject with your own experiences. For some years ( in this forum ) and time to time I posted that the MM type cartridge quality sound is better than we know or that we think and like four months ago I start a thread about: forum.audiogon#Rauliruegas where we analyse some MM type cartridges.
