I think I would like to try a good MM with the EAR 834P - I am open to trying something vintage, but not coming up with availability on the ones mentioned above.

If you want something serious under $700, not just a waste of time and money on average modern MM, then look for vintage Audio-Technica AT-ML150 OCC, Stanton SC-100 WOS or 980, Pickering XSV-3000 or higher number models. Maybe Grace F-9, Victor X-1IIe, Sony XL-50.
Those cartridges are definitely superior to almost everything in MM field you can find today. The reason is the best motors, the coil wiring like AT's OCC, the cantilever (often Boron and Beryllium), the stylus tip (often MicroLine, Stereohedron). And the price for them all is something like $400-700.
it depends on the arm, but AT, Victor, Sony are mid compliance and fine almost for any tonearm. The Stanton, Pickering, Grace are high compliance and better on lightweight arms.
Hope it will help
