What a load of clap trap, A digital interconnect only carries digital data, NOT audio or video.

As for the rest of the gobbledygook on the website, words fail me; I had to look twice to make sure it wasn’t April Fools Day.

Unbelievable (Literally)

It's probably one of the most honest, informative and educational HiFi websites there is , but I accept you might not see it way.

Don't USB, coaxial and optical cables do the same job - transfer digital data from one point to another - and if so shouldn't we be slagging off every manufacturer of these cables rather than just the one mentioned above and, obviously, any magazine reviewing them.

If I'm being stupendously thick here then I apologise but before I start launching into an attack on anyone or their company then I want to know the facts first.

So hearing different cables or speakers is a waste of time then if you can't remember?

don't play with words and stupid questions ,just answer what you remember from track,what is playing in your mind after several minutes ,after hour and what are you missing Tongue ?  Just don't lie at least for yourself Tongue For me you can tell lies,no problem ,I won't believe Cool

An audible difference between USB cables ?

Really ?

Laughed so hard my bum bled.

RE: usb cables expensive v cheap

Do people here actually known what a digital signal is?  Basically it's a string of 1s and 0s and that's all represented by + and - voltages.  Now as long as a cable doesn't convert 1s into 0s or vice versa, and it would have to be a pretty s**t cable to do that, the receiving device can recover the original signal completely.  There is a piece of maths called "Shannon's Theorem" that proves this and that's been known for what must be over 50 years now.

This imperviousness to signal degredation is why CDs don't suffer (in general) from the type of pops and clicks you can get from vinyl and why DAB radio doesn't get the type of interference FM radio can get.  The actual timing of the 1s and 0s doesn't matter either because the receiving device can store the incoming signal in a buffer and take it out at the correct rate.  This is why CD players in cars don't suffer from the movement of the car.

So as long as a USB or any other digital cable delivers the 1s and 0s in a form where they can be recognised as such it doesn't actually matter what it does to the signal.  After all you can download Gigabytes of computer information down a USB cable and it all gets to the other end in perfect condition and a digitised music signal is identical in nature.

So any talk of cables being able to modify the nature of a digital signal in some systematic way, for example enhancing the sound stage or providing deeper bass, is on a par with believing in the tooth fairy.

As I said before, some people will still hear differences between digital cables but what is going on is going on in their heads not in any objective world.

I'm sure that if you were to give me $600 I could make you a USB cable that you could hear a difference between it and a "standard" cable when you streamed digital audio or music

I would make it with material of such a high resistance that the data transfer rate would be so slow that just enough data would get through in sufficient time to be processed for you to hear or see something but most of it would be lost

We must not confuse data transfer with data streaming.  Streaming has a time element involved.  The data is useless if it arrives too late.

How the lack of data manifests itself to the listener or viewer is probably in poorer SQ or PQ.  How they describe this porrer quality is obviously subjective

So you're saying that a wire isn't like coffee in a cup to which you can add milk or sugar to alter the taste??

Does your DAC do this? Very few do.

Most rely on slaving their clock to the input bitstream.

It'll make no difference, but it does exist.

 

And indeed WHF gave it 5 stars, along with the usual guff that perpetuates these myths:

Yep I know.  I just mentioned the possibility because it is there.

Now you're just being silly. How are we expected to understand how these science thingies work without valid analogies such as these?

I'm intrigued that you think increasing resistance would slow down the transfer rate rather than just attenuating the signal.
