DC-powered 2016 Mac Mini -> Pi2AES streamer -> Doge 7 DAC. Big, 3D analogue sound. Sounds pretty good to me, and my listening buddies agree. The Pi2AES is $199, plus $80 for a Raspberry Pi 4 and $80 for Gentooplayer operating system. Same with the Doge, which I got on sale four years ago for $1000. Sabre DAC with all-tube output, no op amps, built like the proverbial tank.
I'd like to hear some newer DACs with I2S input, like a Holo or Denafrips, but I'm not in a hurry. The Doge uses the coax from the Pi2AES. I might try to borrow something from a friend at some point.
