This is exactly why I was waiting on his impressions.
Chico, wait until you try it for gaming. I think Dolby Headphone will make the soundstage differences not as different as you may think. The Annie thows a pretty large soundstage for gaming and movies. Maybe even more natural than the Qs which are undoubtedly, and majestically huge, but not the most natural.
Yes, you're on the right track. I did some dolby headphone tests and the anniversaries behaved more similar to the Q701s in terms of soundstage-presentation than they did in stereo. Dolby Headphone doesn't care much if a headphone pans sounds to the side, and once it's turned ON it makes the anniversaries soundstage wrap around similar to the Qs.
So the differences become less obvious, and I had to run more passes to pick up on them then I did in stereo.
Still there are a few. The Q's will still throw certain sounds a couple feet farther. This is more noticeable with the closer sounds - the farther away sounds get from you, the less you notice a difference in their distance.
Also, the Q701s greater separation means the 65s end up require just a split second more concentration to pinpoint things.
Also the Q701's air is lovely in surround, especially since dolby headphone will slightly softens your highs,which means the 65s take another hit to their air...
On the other hand, the 65s greater body throughout the spectrum gives them a definite edge in the "fun" department, and they sound more home-theater-y. Could be enough to make any differences in the soundstage irrelevant...
So both are good. Q701 would hold and advantage for competitive, and 65s for fun.
