One disadvantage of MM is that stylus assemblies tend to have a rather loose mating with their cartridge housings. Any slight bit of tolerance there will result in some amount of signal distortion vs the fixed assemblies of an MC. Further, MCs have the well-known advantage of a lower moving mass - similar to the advantage of Soundsmiths MI carts. Lower moving mass is a big advantage according to PL of SS, and it applies to MCs as well as MIs.
@helomech Most of the well designed MM/MI have a stylus assembly that screwed to the cartridge body (ADC TRX, Sony XL-50, Technics P100 and P205 series ... ), but even without that screw pulling a stylus away from a Grado cartridge is a challenge, did you ever tried ?
Some of the best MM cartridge have extremely low moving mass too, read about Audio-Technica AT-ML180 OCC or Technics P100c mk4 just to name a few with the lowest possible moving mass.
MC cartridge replacement is typically about 80% cost of new. I don’t consider it very inconvenient. It’s simply a a matter of mailing the old cart to the dealer and receiving a brand-new one in return.
I do. It’s not that simple if your LOMC cartridge cost $4500 and to replace it (when the stylus is worn) you will have to pay 60% of the new cart again. It not always 80%, but even 60% from $4500 is $2700 ! In the MC world even $4500 is not the highest price and i had those cartridges before (never again).
That’s where Excel stepped in and changed the game with their relatively affordable Hana series.
The Excel stepped into the game in the 70’s with wide range of cartridges, they made cartridges for others like SAEC and Argent long time ago. WHy do you think their new design is any better ? Here is my thread about earlier Excel Sound work for American brand Argent in the 80’s
