My Eidolon’s included a forty-five page hard bound manual personally signed by the five people involved with their manufacture.
Avalon Radian owner manual
I've recently suggested to a friend the purchase of a pair of Avalon Radian that indeed sounds very good but unfortunately the previous owner did not had the manual. Wrote to Avalon more than one month ago but no answer yet so I'm kindly asking if somebody has it and is willing to let me have a copy by email.
Thanks in advance!
