Im assuming its personal preference. I found the HD700 in germany pluged to a good rig in mediamarkt in germany and I listened to them for about 2 minutes. I thought "wow, those are perfect!". Then I read Davids review in the battle of the flagships and I wondered if I was really sure of what I heard (bear in mind this was compared to the HE-400). I figured that I needed to listen to a HD800 vs HD700 for a decent amount of time to figure out If I really want to buy em. So far I didnt get the chance.
