I am the original owner. The DAC has been lightly used and is cosmetically like it came out of the box.
This is the original Bifrost: USB, Coax, or optical digital inputs. RCA outputs. Fully compatible with HD but no native DSD or MQA.
Excellent (and better sounding) alternative to an AudioQuest Dragonfly Cobalt for a lower cost.
This can be upgraded by Schiit if desired: USB input is upgradeable and it can be made into a Multi-bit DAC using their proprietary chip implementation.
PayPal. $280 + shipping via your preferred method to US addresses.
