The HD650 presets the music as the producers wants you to hear it. The HD800 is ideal for someone that wants to listen to and exaggerate the difference in to their gears, studio use for tracking errors in the treble, perhaps classical listeners and people that enjoy a colored sound that likes their soundscape "enhanced" by adding treble to the entire soundscape.
The HD650 for everything else, and if one wants to hear more details whilst listening to their music akin to how the producer wants it to sound and sacrifice just little tune purity I recommend the T1.
hehe...this is fun, everyone has his say..and everyone goes home a winner !!
Must say i did enjoy all the hd800 he6 T1 LCDs 650 600 for what they do to the sound in their own special ways.
edit...its criminal.. forgotten about my baby D7k...so so sorry.
