I'd be glad to, but the problem with that is that the headphones displayed in the app are hard coded in. I'll toy around with it later and see if I can find a way for it to scan all headphone configs a user has and display them.
I use it. My settings are attached below. It's main aim is to reduce the treble peaks, which it does well imo. I also developed a tiny app which switches easily between my APO configs. It beats having to manually edit the config files whenever I switch headphones. https://mega.co.nz/#!HINnAJiJ!ggS_iK9cXTV5s9DU6p032EIHg7Ls1YaP6hgBf5vAjuI
Wow some of the posts in the last few pages have been unbelievable. Calling Jerg arrogant because of an improvement he suggested (not enforced)? Whining because of delays? I'm not one to rage over internet talk but that really grinds my gears. Here we have a man dedicated to improving our eventual experience with these headphones, and even our current HE-400s/HE-500s, yet rather than show gratitude he receives the opposite? I don't want to say anything else on the matter...
Mods sure make them better, but twice as good? A little bit of an exaggeration. They are very decent in stock form, just the treble is really bothersome. As for the amping discussion, in my experience they come alive with a good source and amp. Straight from my phone they sound lifeless, totally vieled with no bass presence. With the ODAC/M-stage they're a totally different beast.
