Raul: I will consider the options you've mentioned. I'd feel comfortable if I kept the next cart purchase below 2000 dollars. Some of those you mentioned wouldn't be attainable for me unless I found a good used deal.
Dorkwad: I largely never felt my setup with the MA 2002e was ever thin- sounding EXCEPT in one instance when I used a cheaper, although somewhat well-regarded, class D amp. It was then only that I the sound was "thinner" and a touch dry, but I attributed that quality to the amp. Nevertheless,like you, I have derived satisfaction from the cart for many years and think it's time to look ahead. Thanks for sharing your experience, and I'll look into those carts you've mentioned.
Sinly123: To me, the MA 2002e sounds refined and airy, and possessing the ability to track some rough vinyl terrain and pickup fine inflections. The most likely problems for mistracking where at times loud piano strikes. Other than that, it's been good. I probably could dial-in the tonearm abit more, but I'm unsure, really. By the way, I ALSO have a pair of MA 530MP's that are a step below your 630. I can't really comment on it much as I haven't done extensive listening to it. Maybe it's time to mount it up again.
