I have owned this since I purchased it on Massdrop/Drop back in 2019. I moved to an Amp/DAC combo and no longer need it.

The R-2R DAC contains two PCB boards: the bottom board with power, USB, and different file-conversion technologies, and the top board with the resistor ladders, designed to have the shortest distance between parts for the cleanest results. The hardware includes a custom programmable logic device and augmented power regulation with voltage-stabilization circuits. There is a buffer/isolator stage to each bit on the R-2R ladders, while the output buffer stage boasts five op-amps per channel. Finally, the inputs, outputs, and USB/SPDIF conversion are all located on a separate PCB from the resistor ladders.

These are hard to find and Massdrop/Drop is not bringing them back as Airist Audio no longer exists.
