Don't get why "Audiophile" USB Cable would improve sound quality - Page 5  

Looking at the setups used with the "Cables make a difference" group, its not even an audio signal at that point, its strictly a data stream. If you had a USB cable going OUT from your DAC to <insert device name> there could easily be a difference. Right now, I have a small no name ethernet cable going from a modem to my computer. I never have any dropped packets. Will upgrading the cable to one of these change the way I download content? Will an iTunes song downloaded with one change the sound compared to my cable? It will not, because its not audio at that point. Its just a data stream that needs to be compiled and decoded first. The audio cannot even begin to be decoded until all the data required (this doesnt mean the full track) has been transmitted. Pretty much everyone here spent money on a DAC, yet those arguing that USB cables make a difference apparently have no idea on what a DAC does.

But, in order to stay open minded, has anyone taken the time to objectively test whether or not there is a difference (frequency differences, etc)?

@USG: I don't know. I use monoprice cables as the baseline for my comparison since they are pretty affordable, well-built, and widely known. I love them because they perform the job well. But there is something I do not comprehend (as well as all the people out there) as to why digital cables make a difference. I am open to criticism and will even welcome people to my place to have a listen to the difference together. It is a discovery on my part and I am constantly seeking answer to that (which is why I hang around thread like this).

@ The Pell: I think it has been discussed before that there is no error correction in USB audio compared to USB data and in audio streaming timing is important. The length and type of USB cables we use for printer/harddrive doesn't really matter but we gotta be careful when using a 5m long USB cable for our DAC. Our USB port pushes real-time data stream out and the DAC pulls them in via USB (or any other digital cables). What happens in between is of interest.

Your second sentence pretty much proves what Pell was saying....that it is not an audio signal, but a data signal. If the usb is only transferring data, how can it affect the audio side of things?

What you said is quite confusing.

Are you saying that a $3 monoprice digital cable sounds the same as the Oyaide cable in your sig or that your Starlight usb cable sounds the same as a .98 cent monoprice usb cable?

Sorry if I have confused you. I mean monoprice cables are hard to beat for their price and quality but the cables that I am currently using are more resolving.

I will not recommend anyone to upgrade their cables until they have a good DAC/AMP/Speakers/Headphones. I guess this is the general rule of thumb for cables because the cables are just bringing out the potential of the system.

Now this is even more confusing.

My understanding is that the fidelity of a digital stream is determined by sample rate and bit depth.  I don't understand how your cables can squeeze more sample rate or bit depth out of a digital stream than the monoprice cables?
 

This puzzles me too. I see it as better cables not squeezing/adding more data into the data stream but being able to carry them to the destination with less loss. As a result of that, it will appear as if they are more resolving.

I am not trying to explain the physics behind it but am looking for a convincing reason myself too.

I want to go back to the last statement for a second: the cables that I am currently using are more resolving.

I'm not sure I fully understand what you mean by resolving.   I have an amp that is more resolving than one of my other amps, so I know amps resolve. But I'm not sure cables resolve.  They transmit packets.  If they fail to transmit and a packet is lost we get a drop out.  So, are you saying is that your cables are less prone to drop outs???

Hey. Explanations from what I have read are that certain minute details could not be heard on certain cables because 1) that wave signal gets distorted/lost or 2) arrived at the wrong timing.

Those explanations may be false. Who knows.

I will repeat this statement again: I am not trying to explain the physics behind it.

I have no idea, absolutely no idea, as to why USB cables sound different.

You can ask me to explain, and I will tell you the same thing - I don't know why.

What I want to say is that USB cables do make the different. How it achieves it and why is that the case, we are all waiting for that answer.

It would probably be best to hook it up directly to the mic-in or line-in of your pc instead of running it through a mic.  I'd be interested to see how it would turn out, but I'm not sure if such a test would be allowed on this forum.
