Upgrade Your DAC without Upgrading your DAC! Pi Raspberry Streamer

I've been using my old MacBook Pro for years to deliver digital music to my DAC. I found a far better way that effectively allows me to upgrade my DAC without upgrading my DAC. By using a Pi Raspberry with a high performance digital HAT, namely the Pi2Design PI2AES2.0, I can have noise free bit perfect timing perfect data sent to my DAC via AES instead of USB. And when I upgrade my DAC I will be able to use I2S.
And as a bonus prize, my now redundant MacBook Pro became a NAS to store my digital music library.

I have deliberately not made this a how to video or attempted to review Volumio, because I got the ideas from other people's videos. I don't think it is right to just reproduce what they have done. I wanted to come at this more from the angle of the Hi-Fi enthusiast.

The videos that inspired me most are:
   • How do DDCs improve audio? (Denafrips...  
   • Another Raspberry PI DIY Music Stream...  
   • Raspberry Pi as an Audio Streamer Guide  

I used:
Raspberry Pi 4 Model B 4G
Volumio - image downloaded from Volumio website & flashed onto a Micro SD using balena Etcher.
PI2Design PI2AES 2.0 Pro Audio Shield digital interface board. https://www.pi2design.com/pi2aes-9802...
TP-Link AC750 so as to avoid noise induced by using WiFi.
I installed OpenMediaVault on my MacBook Pro for the NAS (but you can just plug USB storage into the PI)

I don't have one yet, but I will get a iFi audio iPower MK2 Low Noise Power Supply, 5V model. NOTE!!!! The PI2AES 2.0 runs on 5V, not like the old version of the PI2AES
