Hello. This is a lightly used FIIO K11 R2R Digital to Analog Converter DAC and headphone amplifier. It is excellent and working condition, and I’m only selling it because I decided to use the DAC in my existing CD player, so I no longer need an additional DAC. I can ship to the 48 continuous US states and will provide tracking. The player includes the power cord, a 3-D printed mount for attaching under a shelf or desk, and a copy of the instruction manual I printed out. Feel free to ask any questions, and thank you for looking.
