What is the best BNC Digital Cable under $4,000?


I'm looking at the Synergistic Research Galileo UEF Digital BNC. As well as the Wave High Fidelity Cable and the High Fidelity Reveal BNC and the Black Cat Tron Ditial Cables, respectively.  What do you consider the best Digital BNC cable under $4K?

So what, you are saying a USB cable between a source and DAC can make the sound warmer because it has more voltage?

If a data cable doesn’t have sufficient bandwidth, the signal either drops out or stops to buffer.

Transient response, soundstage, imaging, tonal balance, etc. are all impossible to alter with a digital transmission.

Noise rejection & jitter are the only differentiating factors, and even then not by much (unless talking super long runs). Or, are you claiming that you can easily hear these differentiating factors which are lower than -100dBFS?

In terms of digital connections, a better source device and DAC actually have less benefit from higher-end cables than cheaper/worse source devices and DACs. Better DACs reclock internally, so less need for a “low-jitter” cable or an external word clock. Better source devices have less noise, so less need for a cable with better noise rejection.
I will repost my comments:  digital cables are like any other cables inasmuch as their performance is a function of the quality of the voltage and current being transmitted.

Data cables using Star-quad wiring do have much better noise rejection. However, I doubt you have ever in your life heard a Toslink cable that caused audible noise/coloration/etc. to your music, unless you have Superman level hearing where distortion that’s over -100dBFS is audible to you.
I have never heard a Toslink cable so I can’t comment. I am pretty sure I would hear differences in conductor metal, dielectric material, shielding, and directionality.
