These are not your grandfather's headphones-treat them to a better rig.

The store he went to was obviously only using the HD800 as a showpiece. HD800s have a good enough reputation to stand alone; it just sucks for anyone who actually wants to hear them without the ideal ancillary equipment.

It's amusing that all the people laughing at the OP know less than he does.
The problem is not the HD800's impedance level; there's a version of the HD25 with the same impedance and it drives perfectly well from a DAP. The HD800 does not because it is much less efficient. One average high impedance phones tend to be the less efficient ones, but the two qualities are not the same.
Ignorance is bliss in many cases and certainly in this one. I think Daniel is suggesting that there are amps out there which will make the HD800 go from good to great to magical. Which I agree with based on my own experience with the HD800. Ultimately, if you enjoy the HD800's out of your amps that's great but to suggest that the HD800s don't scale with amplification is kind of a dubious claim.
I don't know what is dubious or not, when most opinion are based on some kind of subjectives experiences, and we know how subjectivity is reliable : hearing is believing, but the reverse too. And when someone claim that there's only a small improvement, then you a have proponent explaining that it's the hobby of audiophile to look for any improvements, and that you have to spend a lot for them ; otherwise you don't understand what is hi-fi, or your ear are not enough good. Problem with "small improvements", is that they are often at the threshold of perception, and often it's just placebo.
I don't believe the "scaling" myth, merely you enjoy some coloration / distortions from different sources.But for a standard transparent source able to drive the hd800, you shouldn't have to spend a fortune. Now if the lack of colorations is not enjoyable for you, it's a different matter.

The funny thing is, I know this for a fact. So do many other HD800 owners. Sure it can sound good out of lesser setups-but it will sound better out of better rigs. The difference in this case is that I have experienced both sides of that coin and can confidently state that. It's irritating when someone who hasn't attempted to walk the beaten path chants over and over that he refuses to believe something without putting forth the effort to find out for himself. I'm not claiming I have the best rig ever made for the HD 800 either-I'm willing to accept (through my own journey so far), that these Senns will continue to scale to an even higher level. I'm surely not gonna tell a K 01/Pinnacle owner that his setup doesn't sound/perform better than mine because I refuse to try it. Kids these days....

What a fair attitude. But there also people that have not experimented the scaling after trying different source (such like Takeanidea on this thread). And I didn't notice either much difference when I tried the hd800 at the store with their big amp, and my xonar stx at home.
Also I don't understand all the focus on the amp, the dac is as important, if not more. If you amplify a crappy signal, it's still crap.
