Hello Guglielmo, all our
certified devices have LAN connection and use an external PSU, non-linear by default but it can be upgraded.
With
RuneUI web interface you can control the player from every kind of device (desktop PC, laptop, tablet and smartphone), so your Android tablet does the job perfectly. RuneUI is also designed to be easy to use and you absolutely don't need to be an informatic to play music through it
If you want to play 24/192 or higher files, I suggest you to avoid
Raspberry Pi, because it has some limits (low CPU power and shared USB-Ethernet bus) that make it impossible at the current status.
CuBox should be a better solution for your needs.
Ciao!
