I just got my set of HD650's and am very very happy. Like them much more than my old HD595's. Running them from my NAD 7220PE(old yes but still quite nice). Thorns turntable, NAD 7220PE, HD650 combo brings tears to my eyes... its just so beautiful.

I have both the zune 80(currently getting repaired) and I recommend getting both. Have the clip for when you want a small player and the zune for lots of music and video.
