HD650 is darker which can give the impression of confined soundstage I guess, but compared to the AFO they are a fair bit more open. I have to disagree wholeheartedly with @Badas when he says AFO sound more natural. To me, the soundstage is so small and up front due to them being semi-open that it feels like people are singing to me in a studio of living room size. I remember the HD650 sounding like you're in an small auditorium. Been a while since I listened to them though.
Didn't have long with them, but after the MrSpeakers Voce & Ether C, Senn 800S, HFM HE-6 & Ananda & Shangri La Jr, LCD3 in the same listening session I was struck by how small the soundstage was on the AFO. Clearly it was outgunned money wise, and in terms of voicing it might have beat out the Ananda, but I said out loud - where is the soundstage, and the other fellow that was with me agreed.
OTOH, the Senn 600, 650; MD 4**, Fostex FH500RP, HFM HE-500, Hex v2, LCD2 2C - all cans I've listened too recently have a distinctly bigger soundstage.
Could have been defective? I like all the other cans of theirs (MrS) I've heard, all I know is what heard then.
