Here's a guess on the effective mass...

I've read that the Denon compliance specs are low (they are generally @ least double the stated spec).

Don't know if it's true or consistant.

A local guy successfully used a couple of Denons in the same arm I use (12.5g effective mass) but, I think he swapped in a slightly heavier and much stiffer headshell.

I still use the old stock perforated SME/Sure headshell, but once had excellent results using a solid Technics one with an old, old Grado. (not the 15 year old Grado I currently use).

Try researching cartridges of interest @ Vinyl Engine and Steve Hoffman's site to see what arms (effective mass) are compatible
in the real world.
