I've forgotten how good a TDA1541A DAC can sound! Eliminating the CS SPDIF interface chip is a great step forward. I've ordered a second RPi as this one is going to be permanently mounted in the TDA DAC case. I'll make it self contained with access to the USB ports and add a linear 5v PSU.
I'm not a fan of Volumio in its current version, I'm finding a few bugs and the radio station management / interface is clunky IMHO.
