The low end vendors may try to cheat, or not do outgoing quality control. I'd also be worried about the ultra high end vendors not having the test equipment needed.
My question:
If a digital system, with error correction, can can sound better thru one type of cable, does that cable change bits? Because that's the only way it could change how the music sounds, right? They also claim a USB cable, for the low low price of ONLY $499, is better than others. Can someone please tell me if that's the way digital works? Thanks for your time.
If a cable facilitates error free transmission, then the music must sound the same.
If the cable is bad & transmission has error, it’ll likely result in clicks/pops/dropouts, but not tonality changes.
These are my thoughts.
Review and Measurements of Wireworld Starlight 7 USB Cable
This is a review and detailed measurements of Wireworld Starlight 7 flat USB cable. It is on kind loan from a member. The cost is USD $100 including Prime shipping for the 1 meter/40 inch length I am testing. For this review, I compared it to my current favorite, the 6 foot/1.5m version of...www.audiosciencereview.com
Again, Amir has shown that you do reduce mains noise with fancy USB cables. It is just that the mains noise was inaudible to begin with and you just move things even quieter. But this is a demonstration of how cables can make a “difference” in digital transmission while simultaneously telling you that you don’t really need to spend a ton of money on fancy cables.
Those inaudible sidebands reduction have nothing to do with the digital domain but better analog shielding of the cable which isn't correlated to price anyway.

THANK YOU GXALAN!!!To be fair, wireworld USB had measured improvements!

It’s just that the improvement was not audible.
It might be good to use a Wireworld USB cable if you were focused on testing gear.
Edit: But for Ethernet, it’s unlikely to matter if you are using short runs and better than spec. You can run 10GbE of Cat5e for residential distances.
Thank You!Hi-fi Ethernet cable - does it help with network streamer?
Looks very high quality but also expensive.www.audiosciencereview.comDo USB Audio Cables Make A Difference?
Aftermarket USB cables seem to be all the rage with people paying as much as $15,000 for a short run of it!!! Lots of subjective performance reports are out there but none back with any objective measurements that demonstrates any difference.

A new argument has developed that transmission of digital audio is really analog. And for this reason, everything digital can be subject to audible difference from digital audio cables to digital output of streamers. This was emphasizes in a video by Darko Audio saying this explains his...www.audiosciencereview.com

THIS is real world experience, not fantasy.
Digital transition has moved beyond using 2 voltages. There's many modulation schemes, some use a frequency shift some a pulse width change, Ethernet uses pulse amplitude modulation (PAM). Mostly PAM-3 where the pulses have 3 different levels. Noise is not a problem. Standard CAT cable is not shielded and runs of 300' are not uncommon even in these situations and even if the other half of the tray is full of unshielded speaker cables running Amps of current or HDMI cables running Mhz.A cable with high resistance, because of narrow gauge wire, tinsel conductors, or overly long will lower the "1" voltage, possibly the "0" voltage and the voltage difference between the "1" and zero. A lot of capacitance or inductance will make the slope between "0" and "1" more gradual. On a 3.3 volt system, the boundary between detecting a "1" or "0" may be set at 2 Volts. Up to a certain point of severe voltage loss or rise/fall time the detector in the receiver will get back the signal perfectly.
But in that case, are they really overpriced?... is one of the most overpriced cable companies ever. They are made by unicorns in the starlight of another dimension.

TCP protocol corrects any errors with the data transfer! You can copy a file 1,000,000 times and MD5 sum it and it will be the same. If there is a network outage the copy will stop. You'd expect any system to panic at a network outage or retry .G'Day Folks! Long time lingerer, I rarely post, but I'd love an opinion. I've subscribed to Stereophile my whole life and just got April. While the written reviews tend to be an advertisement for the product, John Atkinsons' measurements are what drew me to this mag and quite possibly got me into RF engineering.
On page 150 WireWorld has an ad for cables. They claim:
"...Platinum Starlight 8 Ethernet recreates the most transparent, resolving, detailed, natural and immersive performance..."
to be fair, it's much easier to compare video quality than audio. You can stop two TVs at the same moment and then it becomes clear.A passive cable cannot change bits, and therefore cannot change the sound.
It's funny.
If a brand tried to sell a passive HDMI cable that improves saturation and bokeh, then everyone would be laughing at them.
But change video to audio and suddenly, audiophiles lose their common sense and start believing in magic.
