High-end audio with Raspberry Pi
When you are looking for a small, stand-alone networked audio player with a touch screen you will mainly find big-ass consumer amplifiers. Those that have network support either have no touch screen or are very expensive. So, why not build one yourself? Based on a cheap Raspberry Pi and a high-end digital-to-analog converter this audio DAC handles 24-bit data, sample rates up to 200 kHz and has a built-in 8x oversampling filter.
