The General Electric VRII arrived today!
I replaced the LP stylus with a NOS genuine GE .7mil stylus and got this mounted on the ROK @ 4 grams. Holy crap, this cartridge sounds GREAT on old mono LPs, provided you have a suitably massive arm.
Compared to the DL-102, it doesn't quite have the same top-end air but has better transient response, slightly richer mids and better bass weight. The DL-102 may have more delicacy, but the GE absolutely rocks. The GE also betters the Denon's already impressive ability to reject record noise.
The fact that replacement styli for the GE are widely available for $15, and that it can do 78 duty, seals the deal; the Denon is now listed on eBay.
