Jeff has a PDF on cartridge compatibility available on his website: http://www.audiomods.co.uk/cartridgechoice.pdf
With the provided shim kit, the Series V is compatible with most of the usual suspects. I've read that the Denon 103 might be problematic (for Rega arms more generally), but don't quote me on it.
Jeff recommends the Cardas loom for Naim phono preamplifiers because of their tendency to pick up RFI. That, and the cost of silver has skyrocketed lately, so it represents a more affordable option. The silver litz wiring offers more detail and instrumental texture, but might sound a bit "bright" on a fully SS system. Whatever your choice, I would think carefully about the wiring option - not so easy to change after the fact.
