I'm organizing unused equipment. I'm selling multiple units as they were used with PCs in different rooms. They were used for about six months. They are functioning normally. I currently use both the PO100 and PO100 PRO, and the only difference from the PRO is whether or not you can connect to IS2. I feel that the sound quality of the optical digital and coaxial digital outputs is the same as the PRO. The accessories are all that are shown in the images. Thank you.
