This unit reads CDs on both drives. The audio was tested through the 1/4 inch jack and it sounds great. I did not test every feature or input/output. With that being said, the unit is in good shape and appears to be fully functional. In the event that there are some unforeseen defects, I will do everything I can to make it right. Please see my feedback and reviews.

　　Thanks for considering.
