I had a loaner DX100 for a late, alternate-perspective review on it (still trimming it down), and I spent half a day standing in a cramped headphone shop almost smack under an escalator (hey, we gotta reduce the overhead, pun intended) listening to the K550. Do note that my "amped" vs "unamped" is basically a Galaxy S3 vs the higher quality amp circuit on the DX100. I spend the previous day with the Focal Spirit One so this will mostly be a comparison:
1) Spirit One treble is a bit dark with smartphones (tried other phones last month, then most recently my S3), presumaby for less fatigue, but opened up really nice with the DX100. It's kind of like going from a Focal Polyglass with a busted tweeter to a Utopia, except for my own tastes I'll miss the electric guitars on a Polykevlar/K2P or the drums in a Polyglass V2.
2) K550 treble is louder off a smartphone, but for my own use I took it off to wipe my sweat before my ear drums began to complain. DX100 made the sound considerably closer to balanced and the treble a lot smoother (cymbals don't hurt unless you have it on too loud, etc), but high freqs are still very much forward - not a problem for me since most of hte music I listened to had female vocals. It doesn't get confused with detail either, all notes are audible though some may be softer, or as far as positioning goes, you can only assume it's attempting to put it "behind" the others. Nightwish sounds grand on it, if a bit lacking in bite and warmth on the guitars. Reminds me a lot of the ATH-Axxx series, which were ridicuously overpriced if they were even available here.
3) K550 is no slouch with male vocals either - it was all clear without any hint of some unnatural amount of reverb on some vocalists/passages, at least not on the ones that I have that tended to do that through headphones like the HD558.
4) I had a copy of the PCM layer of a Mozart's Requiem SACD (yeah I had that too then my $125 Sony SACD changer stopped reading SACDs) and positional cues don't seem to be as good as how I remember it on a K702 ; there was Q701 in the store though and that one actually didn't do as well as the K550 in that regard, BUT the pads were oddly shaped thanks to their headphone stands.
