I used a Belden 1694A digital cable for a few years between my streamer (raspberry pi, HIFIBERRY DIGI+ PRO,
iFi iPower DC Power Supply) and dac (sim audio 380 DSD). I was very happy with its sound and you can't beat the cost.
I've been able to hear differences between interconnects and speaker cables since I got into this hobby many many years ago, but never bothered with any expensive digital cables as I just assumed it wouldn't make a difference carrying a digital signal.
After being
enamored with the magic of Shunyata ZTRON ICs, Speaker, and Power cables in my system, I decided to try their cheapest at the time digital cable the Cobra (purchased used knowing I could flip it pretty easy if I heard no difference), and I was amazed at the difference I could hear compared to the Belden. I then flipped the Cobra to try the Python, and again I could hear a difference; maybe a little smaller this time. I then flipped it to buy the Anaconda, and again I could hear a difference; small but there. I've settled on the Anaconda and am very happy with it relative to the price I paid for it, and relative to what I paid for the other cables in my system based on the improvements I could detect.
It would be interesting to know if I had a much more expensive streamer (i.e. something inline with my DAC price wise) if I would hear the same differences I did between the digital cables.
