Insanely great things can be done with a Raspberry Pi for $40.

For audio on the home-LAN the challenge is to get the digital stream of ones and zeros over to the analogue amplifier in best possible condition. Somewhere you have to create an analogue signal from the digital information - you need a DAC, digital-to-analogue converter. For those who want the best possible sound, there are no limits to the creativity.

There are enthusiasts out there chasing the purest 192kHz/24bit sound. Dock the Raspberry with a HiFi Berry DAC Digital-Analog Converter and... OMF!

Or try an Allo Boss DAC with 384kHz/32bit DAC.

I'm not a HiFi fanatic and lack 'golden ears' so I manage with a USB sound card from Native Instruments. Plugged it into my file server and play with MOC player - music on console using ALSA drivers.

For Linux Geeks, here's the ALSA configuration for Traktor 2 USB on Debian 11.
