Most of the time I can't tell a difference but with orchestra / classical music I can.
Also most of the time I listen to music when I'm in a factory with 75db-80db noise floor so it hardly matters how good headphones and source I'm listening to.
It's just at home where I can fully enjoy my flacs with HD 650... Not that I bother listening to them too often anyways.
I'll take good mp3 256kbps master over bad flac master any day though.
As someone who owns a similar set; I can estimate you're probably dealing with the upsampling issue due to an OS configuration issue. You should try listening to MP3s and FLACs at 44100hz sample rate for your comparison. Not 48000, not 96000.
