Nah.. he just handed me the headphone with 3.5 mm jack connector and that's it. He didn't warn me or anything. Later listening to a couple of minutes, I turn to him and ask why, he then told me that an iPod is not strong enough to amplify the cans. He say I should pair up with a PC or the iMac from the store. But sadly, all the stations were preoccupied, so no luck with trying them out. I might go back there for a another try, because I'm curious to hear them in its full glory....
You should go on a meet more often, or go to a "real" headphones store that will provide you with the proper setup and the proper knowledge if you want to hear a flagship headphones in its full glory sound. It is not your fault that you drive the HD800 with your ipod, because i'm assuming that you haven't got proper knowledge about the HD800 so you make this thread, right?
One day you might end up getting a Dacmini > W6SE/BCL > HD800.. who knows right?
