Here are my observation of the bass mod for Q701. With the sticky removed, bass had more volume, treble got slightly more appearing, so are dynamics.
With the sticky on, soundstage was greatly different, though bass is lesser volume but with the same authority. The high "tings" get more appearance in comparison too, those are like the super highs.
So, for you readers, bass mod for the bass and treble up, or no bass mod for the flat sound and wide soundstage?
