Sitting here listening to A Moon Shaped Pool on my trusty old 650's, and I only kinda regret selling my SDR-modded HD800's a few years ago.

The 800's are something special. That said the bleed is insane, and I couldn't warrant them sitting around only being used to listen to Yo Yo Ma and Steely Dan to death. That said, I miss the space the 800's created--hard to beat, but damn those things are big.
