This is a diy product very similar to the ODAC, and though the internal is mostly similar there are some improvement and differences to the device. The main differences come from the galvanic isolation that was added into the design, the separate power supply and no longer being ran off of usb power which will lead to even cleaner sound and less interference. And finally the design of the case and or chassis, with the connectivity options being different from the ODAC. it connects to a Amplifier via RCA out which are connected to the CDAC+. It is connected to the source via USB. Also comes in a Hammond case either transparent blue or black.
