I appreciate your comment and opinion, but you have not heard the Q701. Your post is just based on speculation and what appears to be bias against AKG. Many,many people on Head-Fi tend to post opinions and make statements, both pro and con, on products they have never heard. Everyone has that right, but I would hope that most people would give more weight to someone's opinion who has personal experience with the item being discussed. If you heard them and trashed them, that I can understand. Everyone hears things the way they hear them. Everyone has certain sound signatures they prefer over others. But just speculating and trashing things seems silly to me.
I guess only time will tell if it is more than the green colour scheme causing the different sound. ;) (FR graphs ftw)
Does seem unlikely they changed much. even more so that they objectively improved them.
