This is a combination of the original production run of JDSLabs ODAC revB and O2 Amplifier. I believe these units are no longer in production. Purchased on Drop.com 8 years ago, flawlessly running since then. Hundreds of hours of burn-in time. Note the adapter for the amp could use some love, as it’s taped closed right now. Volume pot occasionally scratches on the amp as well. Overall would say these are in “good condition”, totally working with many years of service to go. Will include RCA cables, USB cable, and charger alongside both units.
