Alpha pads from MrSpeakers ? I have it and tried on various headphones and never really liked it.
It generates lot of heat and discomfort due to angle-design. To me making the pads angled is really not an ideal way to increase the sound stage.
Like Senns, beyer, should angle the driver inside the headphone housing.
Anglepads do not distribute the pressure evenly, that results in the frontal clamps, like Audeze as an example.
Denon's are angled from the factory. And to me no clamp problems, with either Lawton angle pads or Alpha's.
Different strokes I guess. I even like the Alpha's on my Q40's.
