I’ve been using the Sumiko MMT (very odd that NO ONE has mentioned this arm: it has a mythic reputation) for 35 years. Never felt the need to switch: still going strong. And the current Jelco model, at $550 or so, is a bargain. Sounds as good as arms costing 5 x’s as much or more.
It’s compatible with a wide range of cartridges, except for Grado (the infamous “Grado Bounce” [aa scary as it sounds: use your imagination]).
I’ve been using it with Koetsu cartridges. First the (original) black, then the Rosewood Signature, and finally the sublime Onyx.
