I have the remains of an MP11 here (no diamond on the end of the cantilever) and honestly didn't think it was that tall, but then I was part-trained by Roy G himself who insisted that VTA is a non issue (I'd say he's half right here

)
Someone on a UK sighted-subjectivist forum argued about the 2Ms not being suitable for the Rega arm. The shape and publicity pics told otherwise. I am aware of the slimmer-height 2M models but knowing the balance and sonics of this range in general, I think it's more for looks than actual sonics and in any case, 'VTA' can be fine tuned a little by altering downforce 1/10g either way - the 2Ms and AT equivalents have tracking margins for careful experimentation I found...
YouTube vids talking about 'HiFi matters.' DO PLEASE BE VERY CAREFUL here, as many posters there don't know enough or have genuine experience. One cartridge 'expert' I recall, enthusiastically spouting forth his opinions-as-facts on a host of pickups he'd acquired and shown proudly displayed in front of him. This bod hated 'digital,' which told me all I needed to know about his genuine ignorance as to the correct sound of recordings and how vinyl tends to deviate from that, especially with many cheaper pickups.
Anyway, once again I digress with apologies.
Have you seen the top model Rega decks with their own MC cartridges fitted and working? I was stunned to see an Apheta 3 on a Planar 10 (very thin mat) with the arm obviously UP at the back. I mentioned this to their then sales manager (and an old mukka of mine from years back) to be given the Roy Gandy vibe all over again, so hey-ho
