Hello Chris, not an expert, but 33audio has an Acutex 3xx chart showing the actual size of each cartridge of the 3xx chart. This chart probably means nothing compared to the 4xx, but its all we have, and from there we only have speculation. The Acutex 415 seems on the literature to only have compliance difference's, but sounds nothing like the Acutex 420 according to Professor Timeltel, and he has never steered me wrong.
Your take on the Acutex 412 is like mine except the bass is strong like the 420. It has trouble with cymbals on my system. Mostly white noise. I never heard cymbal problems in music before, but someone mentioned it a while back and it has ruined a lot of good music for me, so maybe it is ok for others on there systems.
