I'm going to a headphone meet in Calgary this weekend and I'll be sure to try my HD800s on a variety of amps at the meet. That said, I too am one of those users who is more than pleasantly surprised at how well the Fiio E17/E9 combo does with the HD800s. Very impressive, so much so that I'll have to let some more experienced ears at the meet have a listen to the HD800s on the combo. That said, I'm sure there's oodles more to hear from these babies once I do have a decent amp and DAC.
Cool! I am an HD800 owner in Calgary as well and would love to go to a headphone meet. When and where is it?
