Couldn't you make a modification to the regular HD-25-1 IIs that might make them sound nearly the same as the Amperior because they said their goal was to make it sound like the HD-25-1 IIs?
In your video you said that the change of material provided the Amperior with sound quality improvement.

. All right, it is a classic an updated HD-25, but $349 for a machined-anodized-aluminum cups, added polarizing foam, copper cable, velour pads and basically just the same HD-25s, it should not cost $150 more.
