FS: Resonessence Concero DAC. In excellent, like new condition with the original box and instructions. Can be used as a DAC or a USB to coax out converter. To use as a DAC, you need a
an outboard 5V power supply such as a phone charger. Works fine. Asking price includes PayPal fee and USPS Priority Mail shipping in the continental USA. You can use an Apple IR remote to dim the display and select 2 optional upsampling filters. PM me with any questions.
