Have spent some time listening to the MC2000 for awhile now. Just a few things to note. The upper registers are as transparent and detailed without being harsh or grainy, this is the best I have heard to date from analog. Granted my experience with cartridges tops out with a Transfiguration Audio Proteus, and there may be other cartridges out there that can outpace the MC2000, but I have not experienced them yet.
Secondly the mids are as neutral as JGH described in his first reviews of the cartridge, but I can see where this is not a persons cup of tea, or that system synergy may be an issue if the audio gear demands a full bodied cartridge. It is not that the MC2000 is lean, but rather that it adds nothing to the midband.
So far I have not really been able to form an opinion on the bottom end. It is not thunderous, and at times seems lean. I can work a bit with VTA and see what happens here, as it seems I need to do more work in this region. Also this cartridge is not a macro dynamic bad ass, not like the Ikeda I have.
All in all a very nice cartridge, and capable of high end performance even after all these years. I enjoy listening to it. It has become one of my favorites, and I imagine I will keep it in the ready for nights where I can sit down and fully appreciate its abilities.
