^ for some reason I've never gotten my Q701 to ever have a very airy soundstage on any amp. I mean it is, but not like a K601, K400 or AD700. It's soundstage is basically perfect for me though. Not too massive, but smaller than the K400 I have with the same setup. Maybe mine is warmer than some other Q701s, but highly unlikely.
I do remember feeling that my old Asgard made the k702's soundstage TOO BIG. However that's possible. I guess if I wanted a larger soundstage I could try the Asgard 2 or something with my Q701.
You know what headphone I really kind of miss? The MDR-SA3000? It was so similar to the K702 I had that it got about zero use. It also had weird pads. I guess the SA3000 and 5000 are discontinued. K702 had better bass anyway.
One of my favorites is still the ATH-AD2000, but I couldn't deal with it's awful pads. The wing design on that thing is perfectly ok unlike the AD700. I think the AD2000 and K400 have to be two of my favorites for acoustic music.
Not sure why this K400 has a larger soundstage than the Q701, but I guess I should expect that due to less bass, less warmth and possibly more treble. I'm not usually a fan of massive soundstages. The K501's was over doing it.
EDIT: Guess this isn't the Q701 thread. Whoops
