Is there really a sq difference with usb c digital cables!?
There definitely is a measurable difference for different cables, but its probably not something a human being would detect on an ABX test, and also the strongest predictor of signal quality is the cable length. In some cases audiophile grade cables measure worse.
There's nothing measurable that explains the fantastical differences that users on head-fi and other forums appear to perceive and the strongest logical explanation is a placebo effect.
If you want a good cable just try to find one that is well-made and no longer than you need it to be. No need to spend hundreds of dollars to achieve that.
