Man, I've just read up on these and it's totally made me really curious. I love a mid-emphasized sound and this seems like just what I'd love. I actually have the Triple.Fis now, recabled to bring out the mids and I love the sound, but the microphonics are killing me. I do love the sound though and not quite willing to go for these... yet.
Hearing they're like the HD650s does sound great though. I've heard good things about them for vocal/jazz, but how are they for rock (which is what I'd use them for)? They seem like an upgrade from the Triple.Fis, but I'm not sure if a upgraded Triple.Fi is better or not.
