Going back to the AD900X. Vocals are much more intimate while being much deeper. Much more 3D in comparison. You are simply surrounded by a beautiful full sound. I would say the AD900X would be a nice upgrade over the Fischer FA-011. These AD900X has a higher resolution in the sounds. Natural reverb in vocals and instruments are easily heard on the AD900X. Definition of instruments are much easier to hear and their effects on the AD900X..The fishers not as much again the flatter less forward mids would explain this. You can hear when vocalist smack their lips or take a breath right before she belts out a tune. The resolution of the AD900X is breathtaking at times and something lesser phones just can't do..They simply have a better textured fuller more engaging 3Dimentional sound over the Fischers..I think the Fischers are great cans but is out classed by the AD900X.
Not effective hyping at all lol
