Great impressions! Just a short comment: from my experience, somewhat recessed mids (as compared to diffuse field reference) are quite beneficial to a 3D soundstage presentation, as they convey a more realistic feeling of distance and depth. On the other hand, too much mids presence may sound unrealistically close and impair the spatial presentation.
Sennheiser IE80 is rated higher than Aurisonics ASG-2. May I know why please?
Sennheiser IE800 maybe more preferred to Aurisonics ASG-2, but Sennheiser IE80?
Going by the phones I've heard, this list strikes me as somewhat bizarre.
