Yeah, I keep toying with the idea of getting a DT770 or 990 but every time I visit the beyer comparison thread it puts me off with the talk of nonexistent mids. I'm sure a tube amp would improve that but the bigger issue is that I still don't really know what sound sig I like. I don't know how everyone seems to find it so easy to do a fourier transform of music in their heads! I'll probably just order a pair off amazon where it's dead easy to return stuff. Annoyingly all the recommended closed headphones these days are portables with tiny impedances and comfort issues!
