best MM cartridge...

Shure V MR, if you can find one NOS, in original wrap. They are out there and generally go for $400. Rumor has it that with the come back of vinyl, Shure will put it back into production soon.

I have one and also a MC, Clearaudio Victory H. Its a tie.

I don't have any experience with the Ortofon 2M Black.

You're going to get wildly different recommendations unless you give us a price range and some other information about your system and what you like to listen to. If you haven't seen the forum below, you should check it out. It's long, but Raul has done his homework and he gives the reader a lot of good information.

Who needs a MM cartridge type when we have MC?

great suggestions all! although in current audio evolution the pricey models (>$1k) I can't yet(?) justify. I listen to almost all types of music to varying degrees depending on the mood. From small ensemble jazz to classical to world to flamenco to rock to punk on occassion, etc. I consider my system to be better than mid-fi, maybe even hi-fi! Simaudio I5, Rega Jupiter2000, Joseph Audio RM7 sig, Zu Cable Julian bi-wire and Warmouth IC. Current table is a 'found' Yamaha P220 with unmarked Audio Technica and a cheapo phono pre I picked at a TV repair shop for $25 new. I have an AR ES-1 on the way w/Linn Basik LVX arm and K9 cartridge. So I'm also thinking about phonos in the <$1k range.

Mingles, I started to read that tread but 'lost it' mid-way through! The AT150 is an interesting suggestion, how would it compare to the Linn K9?

¿So where is Raul?... oh well, I,m almost sure he is going to say something like: What,s the best MM.. but for what arm?
but lets wait for his opinion. As said above check out his previous threads on this subject.

what about one of the Grado References? Moving iron instead of MM but same output.
