USB DAC/Headphone Amplifier AL-9628D This is the AL-9628D from Amulech. The USB to coaxial conversion was convenient, and I couldn't part with it, but I no longer need it due to a change in equipment. It was working perfectly fine until I removed it today. I don't think there are any noticeable scratches or damage, but please understand that this is a used item before purchasing. The items for sale are only the main unit and AC adapter, as shown in the photos. Thank you.
