Is anyone using a HDMI cable for I2S connection between digital components?

@stuartk Most use an HDMI connection but can vary in their pin configuration that can lead to incompatibility issues.  Best to check with the manufacturer if a given DDC or streamer is compatible with their DAC.  

To all... thanks for the info. It's as clear as mud now. 😂 haha

Any HDMI cable should work.  Its matching the I2S pin settings of the sending and receiving gear.  Denafrips has several videos that cover this.

Unfortunately just like any other Audio Cable there is a difference and a high quality cable ($$$) is better.  My first HDMI was $ 100 and was better than the free one with the TV.  Then to a $350, then to $ 850.  Its like USB cables, quality (price) changes everything.

OK -- thanks for confirming that. 

You can get AudioQuest Cinnamon HDMI 4K cable for $29 on Amazon. Silver plated conductors. Good build quality. 

Best bang for the buck.
