User UNW209 recently posted a picture of what seems to be a succesor to Ultrasones Signature line : "It is shown in an exhibition in Japan last month. Neither retail price nor release is known." Quote from Head-Fier UNW209. There seems to be no other information regarding Ultrasones new Signature headphone though, I've sent an e-mail to Ultrasone and I am currently waiting for a reply with more information. Any updates from other Head-Fiers will be kindly welcomed !
