I'm also interested in H180 mod, if you decide to do it, let us know how the sound changes with each step, at least if it sounds better/worst to you. My H180 arrived today, out of the box it's not musically satisfying to me, they need to burn-in for a few days. I re-cable my Vido and I'm giving them a second chance. The diaphragm of the right driver was hanging so had to glue it, I used the tiniest bit of nail polish/varnish, making sure it didn't run to the diaphragm. They still sound good.
