Based on having an old MC20 still kicking around and having gone through the Cadenza / Kontrapunk / Windfeld / A90 lines - no, I don’t think a new Cadenza will the same "house" sound as your MC30 Super. The older motors used very low impedance coils coupled with large, relatively weak magnets (very different from the small strong neodymium in Cadenza). Honestly there's a kind of beauty to that type of motor’s sound (what you refer to as its musicality), though it’s also very demanding on your SUT and/or phono stage due to very low output levels.
Not saying you should’ve also give the modern sound a listen. But I’d definitely look into getting that MC30 refreshed if I were you!
