well, I get back home yesterday and put back the original foam filter. after 100+ hours the fuzziness gone and I got back the original separation and depth.
However, I can relate with @derbigpr that its not engaging enough and I did skip a lot of my song, but I realize something, i almost never skip a track when I listened to evo while I laid my back on sofa or reclining chair. I can't understand why but at some position, when evo are pressed from the back it seems that music are drawn into me, and suddenly it became musical and engaging.
Maybe its just me? last night I tested and Daft Punk - Giorgio by Moroder sounded soooooo great! never heard it sounded that great before. Also song Queen by Etana gave me unreal impressions that I never heard. might have something to do with back of my head / neck pressed and angled the evo / my inner ear?
