IIRC, your old Audioquest B200L is a low output cartridge. If $1500 is your cap, there are a lot of good performing carts from Ortofon and Audiotechnica. The AT-OC9/II or /III will perform nicely in your arm cart combo. Stepping up, the AT ART9 may provide you with a very good listening experience. The Hana SL is also a good cart, but not in the same league as the AT's.
Don't expect the Rowland phono section to be able to keep up with the modern phono stage offerings. But it is, in itself, a little laid back.
