Well, why not just try it and we will know.
Why does this particular post seem familiar to me, where did I see those identical pictures?
But posted under another name?

[Guide] List of I2S DACs for Raspberry Pi

Postby AlexD » Fri May 12 2017 12:11

Hello everyone,
I would like to introduce my new DAC:

24bit 192kHz
Burr Brown PCM1793
Sound-Plus High-Performance, JFET-Input Audio OpAmp
Susumu thin film resistors
Nichicon audio capacitors
WIMA FKP for filtering
Low-Noise regulators

This DAC works with an external power supply, it requires +-15V
The supply for this DAC is completely independent from the Raspberry. This is one of the reasons for excellent audio quality

Image

It can be purchased at my webshop:
https://dial-audio.de/shop/diy/

I have also kits for the powers supplies, send me a pm for prices etc.

GY-PCM5102 is a tiny purple i2s DAC with a line out stereo jack, and costs as little as $4. It can be found on Aliexpress, eBay and Amazon. I wired it to a Raspberry Pi Zero W, as in the photo, and selected the HiFiBerry DAC device setting in Volumio. It appears to be working well!
