Looking for an R2R DAC HAT?

Greetings. I have multiple Raspberry Pi devices running various DAC Hats. Out of Curiousity I would like to try an R2R DAC HAT, but am having trouble finding one. I am not really a DIY guy so buying a kit is beyond me. I searched the forum and could not find any refernce to an R2R DAC HAT that is recent. Just looking for suggestions. Thank you for your help.

Maybe you’d need to use a Raspberry Pi 4 or later and get a USB connected R2R DAC.

I found an R2R DAC Hat on DIYAudio and the post is from 2025, so not too old.
The listed cost was $216 + $39 shipping to US. My curiousity does not extend to the dollar amount. Very happy with the Raspbaerry PI’s and DAC Hats I am using with Volumio.
Thanks to all that considered my intiial inquiry.
