Give Bluejeans cables a try. No hocuspocus about their cables.
We (Cherry Amp) have high performance digital cables. I agree about the hocus-pocus. If the signal gets there without errors, there should be no difference in the sound from anything else that gets the signal there without error. Here are our cables:https://www.cherryamp.com/accessories
We don't try to make money on cables, by the way. That's not our thing, so we sometimes provide them with equipment purchases at barely-above-cost or even free occasionally, depending on the order. The prices listed on our website are significantly higher than we what actually charge for some items, because we sold them on Amazon years ago. We currently sell MEGA Speaker Cables (9-gauge equivalent, 8-foot length, banana plug terminations, flexible braid) for $90/channel with the purchase of a new amp, for example. They were $450/pr on Amazon. We stopped selling through Amazon because their seller support was an absolute nightmare. Ask any Amazon seller about that one (:
Our fancy coax SPDIF cables are BNC with gold RCA adapters included, typically 1-foot length, and made from cable capable of digital video speeds, so there's no worry over signal integrity. The "thin wire" type is also very flexible, and we now have a 3-foot version. Our primary reference system uses the "fat red" type (photo).
Just as an exercise in science, we tested SPDIF cables for data accuracy, and the fancy cables we make do not outperform the inexpensive one we typically give away with our DACs. In fact, we do our production tests with the inexpensive one because it works, it's flexible, reliable, the connectors aren't as tight of a fit (gentle on the DAC's connector), and it's 3-feet long for easy hook-up.
