I have very good MMs, but they have no advantage over MCs (and don't forget Deccas, which are sort of on their own configurationwise).
Geoff, if you can hear the differences at the very top-end then for your age you have the hearing of a bat.
I would say that MMs and MCs present music differently, but it's not so easy to say one is better than another. IME good MMs are more propulsive and solid sounding. MCs will tend to have a more delicate mid-range. Good MMs can do treble better than many think but MMs are more picky about electrical loading. Many MMs want to see just 100pF but most peoples' arm wire and interconnect and then phono stage will often present more like 300pF. Couple this with the inductive load of some valve phono stages there can be lot than prevents an MMs giving it's best. Also 47k often isn't the correct loading. By a good MM I'm meaning one with a line contact tip attached to at least a boron cantilever.
In comparison to Decca....I've had a London Super Gold, London Jubilee and currently run a London Reference on my 301. On the deck beside this I run a Garrott P77i modified by NWA with a Boron cantilever. I also have an AT150MLX which too is line contact and boron. Considering the massive difference in price it's quite interesting to compare the sound. The MMs easily outdo the London in the bass. The London pulls it back in the mid-range with greater openness and clarity but at the expense of some thinness. The treble quality is harder to call. I'm hard pressed to express a preference between the Reference and P77i, it's that close. The London BTW works best in my system with my valve / LCR phono stage loaded at 33k. The MMs are better with one of my solidstate phono stages, with which I use a short unbroken low-capacitance cable from cartridge to phonostage.
