Summary: The sound quality this little box produces to my beautiful A40's was phenominal. However (and I had feared as much with the product being used and all) the dolby digital surround sound button wasn't working correctly and the optical in port was broken as well. The customer service however was exceptional as far as getting back to me within moments and quickly sending the return shipping label.
