I am in for sure. I would like to see SONY PHA-2 Headphone Amp(https://www.massdrop.com/vote/ipod-direct-digital-portable-headphone-amps) get dropped as well as the front end to pair with these. Any thoughts? Also a drop on O2 + ODAC Limited Edition (desktop version) would be sweet for K712 too :)
Guys lets make it happen
