I use Van Den Hul's Opticoupler toslink cable ($120) which can be purchased with a mini-plug which negates the need for a adaptor plug when connecting to the AE. After calling around to several Van Den Hul dealers, I found mine in stock at Eugene Hi-Fi ([email protected]) in Eugene Oregon. I have no affiliation with Eugene Hi Fi... just a satisfied customer... very friendly, knowledgeable and helpful over the phone.
