I've owned them for 10 years and totally love them!  

hmm, seems like you're living in the 90's lol. I think you'll like the HD650 also. (and get a better amp)

Lol, what can I say, I'm a 90s kid! I just bought these because they are basically a less expensive HD 600 (which I'm planning on buying very soon...). I already love the sound from the 580s, and I know the HD 600s are better but I'm trying to wrap my head around that because these already sound so good! As for amps, I also plan on getting the O2+ODAC.
