Yes! I posted in another thread that I mainly listen to Sleaze (also known as "the New Wave of Hair Metal") - I'll post a few YouTube links at the end for those interested to hear what it's about.
I have an SE84UFO, and the things it does with metal is really cool. Probably my favorite thing is the way drums sound with the amp. Despite almost all metal having a very produced way of recording drums (lots of close mic'ing, heavy compression, etc.), the Decware amp really makes drums sound more natural than any SS amp I've heard. The Decware also does a really good job conveying the sense of space in a recording - that is, any reverb in the recording (real, or more typically, artificial) really comes through and adds a whole other dimension to the sound that typically SS has a harder time rendering. Other than that, distorted guitars sound great, bass always has a satisfying presence and vocals sound great. When the whole system is set up right, the Decware also creates a really "fleshy" center image, so singers mixed center have a real palpable presence.
In short, I LOVE metal with my Decware. It makes it an experience.
That said, I've said it before, and I'll say it again, but for me, I think a preamp in front of the Decware really helps add some weight and density to heavier music. You can get away without a preamp, but there is a bit of a loss of power and energy for me. I currently have a Slagle autoformer (or Slagleformer) in front of my Decware - it's a passive, but somehow it has that same addition of weight as an active amp. (Planning to start a discussion about these soon, just have to get some pics together first).
Anyway, here's some "classic" sleaze tracks for those interested:

Also, it's not sleaze, but I love the way the drums are recorded on the last few Dragonforce albums, and think this cover of Johnny Cash is some of the best drumming I've ever heard - and the Decware doesn't miss a beat playing it:
