I am using the SME IV arm with the top Dynavector cartridge (the XV-1s). This cartridge is an outstanding performer, and the SME IV and V series arms pair exceptionally well with the XV-1s. IMO you should definitely put the XV-1s on your short list.
Cartridge for SME IV.V
Attention SME arm people - I'm looking for an upgrade path for my SME 20/2A table, and would love to hear what cartridge characteristics make for a good match with the SME IV.V arm. I am currently using a Dynavector 17DmkII which performs reasonably well, but I imagine the arm and table could handle a better cartridge. Any thoughts?
