i run volimio on a RaspPi 3B+ to which i hooked up a HifiBerry Amp2 ... connected to my self-crafted 2-Way BassReflex Visaton speakers ... the sound is amazing! ... i like it very much ... i control it from my main pc when i sit @ my desktop ... but sometimes i also control it from my smartphone (android driven) i.e. when i'm in the bathroom or just chilling on my couch ... i've put a 64GB USB-Stick (very tiny form factor) in one of the 4 USB-ports for storing my music ... and i configured a samba-server via ssh on the rasp to get easily access to the stick from my pc ... working fine ... i also enjoy the capability for hearing internetradio ... may be i upgrade to MyVolumio in the future ... you volumio people did and do a very great work!
