RPI based preamp. dac. and streamer.

Hey guys,

As i require a desktop pre-amp, Im planning on building an High-end integrated unit built around a Raspberry pi 3B+.

Ideally this would have a few inputs, a headphone output and a RCA out to my Stereo power amp. Raspberry pi would have a ~1.5" screen and some GPIO buttons to control play/pause/next/previous. Volumio would be the software of choice Feeding a ALLO Boss or Katana.

Im wondering if this kit would be a decent starting place to begin.

Is there any other kits that would provide a higher quality sound?

Any other suggestions or similar builds are welcome!
