Should I add a DDC?

Another thread here addressing the same. I won't go into detail as I did on other thread, so in a word, yes, and get the OXCO clock Hermes or Gaia.

Great, thanks guys, well done, you've got me thinking Hermes too now 🤣

@painter24, this would be my fault. Apologies my friend😬

I added a Denafrips Iris DDC to my Pontus II last year and Ithought it pretty clearly improved the overall sound.  I’m using an UltraRendu with a LPS in the setup.  Best of luck

Absolutely it will improve the sound on any USB input, I use an Iris with my Pontus II. Just be sure to use a high quality HDMI cable. Supra 2.1 HDMI are good for the $60 they cost, but something like the Audioquest Vodka 48 8K/10K is what I settled on.
