I reccommend Phaelaeh, Shpongle/Hallucinogen, Mood Deluxe/Nagual Sound Experiment, Chillosophy Vol.2,
Anahata - The Unmade Sound (deserves its own sentence)
btw I just gotta say my K340's are awesome
Nice low bass (prbly bass-heavy ones)
Smooth as butter mids.
The W5000 mids reign supreme for me sometimes by being coloured and forward making some songs unreal/out of this world. And inversely my YH100's would win for transparency.
If ONLY there was a way of modding the drivers into another headphone. (The w11jpn for example... so expensive tho.. w10VTG maybe?)
Or you could pay someone to make custom wood too, though.. s2 audio maybe?
