Have you ever had a portable amp that made your HD-600 sound better than your $200+ monster amps? I've heard of this with some people using the PA2V2 and some CMOYs. HD-600 sounds great from my Total Airhead. Uses the AD8397 opamp. That one seems to be in everything. Even the PA2V2 I think. They all sound different though it seems.
I wish my E11 had the mids of my Airhead. I'll have to try the PA2V2 sometime. I also need to try my HD-600 more with the E9.
