Upgrade Rega Exact2 on built-in SUGDEN A21aiS2 Ph

At least for the acoustic music I listen to, I doubt if MP-200
can be beat at that price point.And I've owned at least a hundred carts in the last 40 years. Definite upgrade from Exact . I doubt 300 is much better.

Dear Schubert.
Thank you for the information.
Please let me know what cartridge you recommend?
My budget is around $500.

MP-500, but 200 is almost as good.
