The Pi Preamp V5 This is an evolving project and has things yet to be implemented. As it is working and I am too busy to finish it right now, I decided to throw it out there. This is a high quality digital preamp with an Allo PCM5142 DAC that outputs 384kHz/32bit in 2.0 stereo mode and 192kHz/32bit in 2.1 or 2.2 stereo mode. The right and left signals then pass through a Music Fidelity tube stage. It runs as a streamer, it has free radio services and will play from various sources including your phone, device or NAS storage and runs music services from the console or remotely. You can control it and stream through it from a wired or wireless LAN or Bluetooth. The system is set up to run 2 powered subwoofers straight out of the DAC and right and left channels are redirected through the tube stage. So you have right and left stereo analog outs and 2 line level subwoofer outputs. I have not tried to use the HDMI's for output, but I'm sure they would work although this would bypass
