This is a spectacular sounding DAC with coaxial, optical (Toslink), and AES/EBU (XLR) inputs. Coaxial connection is via BNC->RCA adapter which is pictured and included. The cover plug for the Toslink connection is not pictured but is also included (the same goes for the power cord). The owner's manual is included and covers all the details. There are a few light marks on the edge of the faceplate (see photos) but overall it's in excellent shape with zero issues in terms of functionality. Stereophile Class A DAC, read the reviews. Will be shipped in its original box with form-fitting foam to protect the DAC Guaranteed as described.
