It’s about the synergy more than anything. An experienced dealer that knows Naim MM phono stages would likely steer you towards four or five known carts that sound great with it and steer you hard away from some others that really don’t work so well. And yet they probably all have the same 100-200nF loading.
@DarkCat - Believe you have a Nait XS3 - from your previous posts…?
As @feeling_zen says, a good Naim dealer could guide you, as to a suitable cartridge which would work well. I think I am safe in saying that the DV10X would be one of those.
