To my ears USB cables do make a difference.

Blocking interference in the cable improves the signal quality. All transmission is liable to be corrupted and that is why there is the concept of acknowledging reception of network packages in TCP/IP and getting corrupt files on the Internet is rare.

Digital audio transmission is real-time though and corruption will not be fixed with retransmission of a USB package. In case of USB audio there is no error-correction too.

Buying a well-shielded cable for USB connections audio gear makes 100% sense. It does need better shielding than the average cable for the reason mentioned before.

Interference also adds jitter to the signal, but this is difficult to explain here.
Thanks for that detailed reply. Hopefully Bill could pop back and answer too.

I don't think new forum members would simply buy stuff, because a stranger on a forum says so
I think plenty would (and that's the issue here).

Imagine if post #1 was the only post on this thread.

Re-read it.
To a newcomer, that is better than an advert from Chord themselves - as it gives the opinion of a user.

There's every chance they wouldn't question that opinion.
(Subsequent posts have done that important job for them).

But if someone did buy such a cable, heard no difference, surely they would send it back for a refund ?

Its what buyers do when purchasing Amps, Loudspeakers etc right ?

It would be nice to think so 👍
I wonder how many do.
There's a touch of 'The Emperor's New Clothes' syndrome going on.
They may believe that their hearing and / or equipment is inadequate - in which case they'd still be better off returning of course.

But I suspect many a cable is sold to underwhelmed, disappointed people who may not wish to accept that they were fooled.

On the other hand, if you're a glass half full optimist then a cable could be "wow", the best thing since sliced bread.

If you get the impression I think it's more about the person's mindset....you wouldn't be wrong 👍

Thank you for your kind comments.
It is a conversation to be had.
In all honesty, I was expecting simple feedback from people who had tried different usb cables but never imagined such polarity 😊
For the record, my Supra USB cable is probably the same as the one you replaced and to my ears, it does make a difference when compared to a no-frills one.

USB cables use computer protocols to transmit data (If they didn't they would not be able to communicate with USB equipment, so checks and balances are in place.
You are confusing sp-dif with USB, sp-dif does indeed transmit the digital audio data live, however USB does not.

The article clearly states that "All audio data is transferred over isochronous transfers" and that for isochronous transfers "The data has a CRC as normal, but if the receiving side detects an error there is no resend mechanism.

That proves you're new to cable discussions 😉

There are Audiophile fuses that might be of interest to you 👹
Nope, I've been dipping in and out of What HiFi since the 80s, those days posting your comments by post was the norm.
I can't recall the name of the magazine author, was it Michael Hughes?
There were discussions around solid core mains copper vs traditional multistrand speaker cable. This old cloth is still being used today 😊
Have a beer on me🍺walks up to the bar counter and tips the barmaid.

Judging from the products he reviewed for TechRadar, this is a necessary skill.

How would you spend thousands of pounds on anything hi-fi if it doesn't make you ecstatic?

And I seem to remember he was one of the reviewers where you thought, "come off it mate" as you read.

(But there have always been those ones).
Yes, ha ha ha. I did buy rolls of solid core cable (and experimented with fuses, Ok that's the nail in my coffin ooops).

I hear a little voice in my head "Jason Please Stop", I dare say, there was something in it, a smoother rounded sound, less brittle in the treble than multistrand but bass not as extensive as the latter.
I use to have those Edison monoblock tube amps , I purchased as a kit from the advert pages of What Hi-Fi, my God these were amazing, 12 watts of solid class A from each mono. It seems insane that these amps were able to power up the massive Musical Fidelity boxes. It's the same question you ask, while you're knocking back the latte, how is it possible for a bubble bee to fly?
How is it possible indeed for USB cables to sound so different? You saw what I just did? :)

I had these solid core wiring bridged to my Musical Fidelity Speakers and music source courtesy of Marantz first generation front tray loading CD player. Beautiful champagne gold and built like a brick...something house.
CD players was in it's infancy then, I think the Edison monoblock tube amps and the solid core speaker wires played some part to the top end smoothness. OK best to stop there :)
