That is possible, I haven't heard the Q701 in a long time, I'll need to revisit it sometime. They may of retuned it a bit on the newer models as AKG does have a tendency to silently change the K7 series. The HD 650 does have a strong central image and good depth as does the K712. I always found the HD 650 to have good depth soundstage wise, but width varies widely on the system with it. It could be that the center hole isn't very noticeable until you put on other headphones, it wasn't till I switched back to the K712(I didn't have any other comparable headphones to the Q701 back then), that the center image bothered me.
