So Denphals are crosses between dendrobiums and phalenopsis? Is the den parent the den nobile? And I presume sympodial is the dominant trait since the phal parent is monopod.

No, the "phalaenopsis-type" Dendrobium is named for the species Den bigibbum (that used to be called "Den. phalaenopsis") that apparently reminded someone of a Phalaenopsis. (I don't think it's even close) It's the dominant ancestor of this group of hybrids. But Dendrobium and Phalenopsis are quite unrelated and certainly don't interbreed.
