Thanks! That's exactly the advice I'm looking for, I just need somewhere to start. I've read exactly the same thing you did about I2S cable length so I think starting with a $7-6" cable will do the trick for now.
I2S cable recommendations
I just purchased a Denafrips Hermes DDC to connect to my Pontus II DAC via I2S. Anyone have recommendations for an I2S cable that is < $200? My budget is a bit fluid and am willing spend more if the value is justified by the performance. TIA.
