![]() You will need a minimum of 4GB capacity, though 8GB is preferred. Given that the cost of the Raspberry Pi 3 B+ has come down, I will still recommend it as the best option for this build.Ĭost: $35–50 USD (Availability influences cost) SD Card Most Raspberry Pi boards are overpowered for what we need to provide for the DAC hardware and supporting OS, so I was not worried about using a Raspberry Pi 3 B+ instead of the Raspberry Pi 4 inside my streamer. When I built this streamer, the Raspberry Pi 4 was just released, with support for the X400 V3.0 DAC not stated anywhere. I chose a power supply that provides 19 Volts DC and 3.42 Amps, more than sufficient to power both the DAC and Raspberry Pi. The X400 V3.0 DAC+AMP board requires a power supply capable of providing 6–26 Volts DC, with >=3 Amps recommended. ![]() I went with what’s arguably an overpowered solution for my power supply, but past experience with Raspberry Pi’s and cheap power supplies has me erring on the side of “enough, constant power” versus “just enough” power. When choosing a power supply, ensure it provides enough amperage I found an audiophile headless operating system named Volumio ( ), capable of providing all of the headless media streaming options I wanted. This gave me the flexibility to run whatever operating system I wanted, access GPIO (general-purpose input/output) pins for additional capabilities, and a large equipment ecosystem that allowed me to pick what I wanted. What I settled on was building a small Raspberry Pi with a DAC board built into it. It would also prove to be a fun project and stretch some of my knowledge of audiophile equipment. This left little options, other than buying a very nice wireless DAC or similar device.Ībout nine months ago it occurred to me that I could build what I wanted, far cheaper than most solutions. I also wanted a solution that didn’t have me vendor-locked, like using Chromecast Audio or Amazon Echo. ![]() I wanted a device that could stream audio from a media server like Plex, not be reliant on Bluetooth for connectivity, allow me to use my existing speakers, and provide high quality audio output.
