So you confirm my point. If you compare a headphone with the pads mounted with clips and then compare it to sealed pads with sticky double sided tape, there will be a remarkable difference in bass level. I had LCD2 v2 while having HE-6. I sold LCD-2 v2 because it was inferior to HE-6 (with Audeze "vegan" pads) in all imaginable ways - except bass. Later I have changed from vegan pads to HM5 pleather pads and the difference in bass amount and quality as well as punch and dynamics is substantial - if not dramatic.
