On the Stax thread(new) I saw rumblings about this earspeaker from Stax called the SR-507. I tried to research but, surprisingly, there is little information on them other than basics. Supposedly they are due in September, 2010.
I wanted to start a thread in order to collect any and all pertinent information that people from head-fi have.
Thanks and I am loving my 4040II Sig System and wonder how this new earspeaker will measure up.
