I'm listening to the Labyrinth Soundtrack from 1986 and according to Foobar this is my 47th time. The HD800 makes it feel like the first time. There is so many details I never knew were there. For example, I just finished the song Magic Dance and there is a goblin asleep and snoring back in the soundstage. Every song I'm discovering something new! The layering is fantastic on these.
Also the leading-edge is so defined yet the sound is very smooth. The more I listen the more impressed I become.
