Personally I would x Usher off the list for Metal, at least the one I had. Dynaudio are pretty goodish for metal but need some beefy amplification. Never heard the Evokes but the Focus series was really nice for that kind of music. There is a Focus 140 for sale pretty cheap on another site. older but really fun speaker.
I would absolutely recommend Tekton for metal. The newer Paradigm Monitor SE series are also fantastic for rock and metal, much better IMO than some of their higher end series for that kind of music. You don't want a straight up audiophile speaker that looks at everything under a microscope for that kind of music.
