I'm curious about tossing in a 2mm thick "trap" for higher frequencies with melamine between the driver and the ear pads. How would that do? Would it be excessive and kill the highs? Anyone have experience with what melamine would do to the frequency response?

Hello, all. I'm hoping someone can help me out here! After looking at frequency responses between the 400i and Sundara, I've decided that the Sundara isn't worth the $$ (nor is it really affordable to me unless I were in the U.S. which is not the case right now). Anyway... I can't get any info...
