I used a JSD5 for several years, and Ninetynine's description of the JSD6 pretty much is what I heard through the JSD5, but I have not compared the two. Not the most resolving cartridge, maybe on the warm side of neutral, but among the best for playing music. My view is that a lot of cartridges these days tend to sound closer to (very good) digital in many respects, but the EMT cartridge sounds like analog at its best. I still own it, in reserve for my Air Tight that replaced it.
I would have to imagine that somewhere on the internet there is something that would explain the theoretical differences between the two types of styli.
