I have several Volumio streamers and this is my latest permutation. It’s the coolest ever! It’s tiny and sounds great.
It’s made of the following components:
Pi Zero W
Apple USB - C to Headphone Adaptor (DAC)
64gb Samsung Pro Endurance SD card
Zebra Zero Heatsink Case
Kuxiyan USBC to MicroUSB adaptor
Canalkit 2.5 amp power supply
I’d estimate total cost (without shipping) at < $75.00
This feeds into a Sony STRDH1090 receiver (100W) and Elac UF5 floor standers.
The SD card holds around 250 CDs. The set-up is tiny and sounds great.
For two years, or so, I’ve been running a Pi 3B+ with a HiFi Berry DAC + Pro which is nice. I had hesitated about using a Pi Zero for this but it works great. But the Pi- Zero based streamer wins the prize for coolest form factor, hands-down.
I love it!
