Headphoneus Supremus
I'd expect a mid priced open back next.DCA has always been very tight-lipped about future releases, but at some future date they will surely introduce a successor to the Stealth. They typically introduce new models either before a big (NYC/LA) CanJam, or just in time for holiday shopping. FWIW.
E3 price but open.
Or an Ether 3 as in round shaped planar headphone like Corina/Ether2 but with AMTS
