I've been meaning to post for a while but i've been busy as of late. Here's my latest and final mod config. DBV V3 except with the following changes.
1) No felt over the driver and no treble reflector
2) Bass ports 100% sealed
3) V- Moda replacement cable
The result is a pretty dark sound but with really good instrument separation (as good as or better than my k702s) with a really nice strong resonance (think denon d2000s except more exaggerated) with bass that extends low with lots of impact. I know that that's a lot of superlatives but these have replaced the k702s and denons as my most used/favorite headphone through my psii after the aforementioned tweaks.
