No way could a Dual arm handle a Denon. It might fly right off the record on the first bass drum hit. ;-)
Krazeeyk,
The concensus looks like the OBH-8 route. There's no MC cartridge < $200 that will play with a Shure V15VxMR on a Dual, so if you can stretch that far get one. It's good enough to embarass some cartridges that go for 2-3 times the price, and it should work very well on a Dual.
