I bought these from Audio Advisor just over a month ago. But I rearranged my rack and equipment, so I no longer have a need for them. They've seen very little use--had them on my DirecTivo, but I ended up using the Toslink output most of the time. You can check out the specs below: http://audioadvisor.com/store/produc...asp?sku=AQCOP1 I'm asking $50 shipped and will consider offers. Contact me at: [email protected] Thanks!
