I was searching around for DACs with balanced output, and came across Yamaha AG series mixers. These mixers can record at 24bit / 192KHz, but for Volumio the best feature may be same quality playback of computer audio.
At $149 list and $127 street price, Yamaha AG03 may be the cheapest DAC out there with TRS or XLR balanced outs. It also has excellent reviews across board. Does anyone know of better options in this price range? I am thinking of pulling the trigger on this one.
My plan is to use Volumio RasPi2 -> DAC -> Active Reference Monitor speakers for two-channel listening.
