I haven't heard the Dreadnaught II, but I own a pair of Enterprises and an Intrepid (5x100), which should be fairly similar, tonally, to the Dread. I am very happy with both of them, and the soundstage, imaging, and detail from Theta Digital amps are what I really love about them.
I'd go for the DreadnaughtII, although I am certain that the EAD is also a worthy option.
