I tried my printer cable with my DAC to see if it my DAC sounded the same with this cable, as it did with the stock cable.
The DAC's stock cable looks just like this one:
The printer cable looks just like this one:
Both cables are the same length, which is 2 meters.
As soon as I listened to my DAC with the printer cable, there was an obvious difference in the amount of bass or bass impact between both cables. Bass quantity/impact was lower in the printer cable. Without saying anything about this difference, I asked someone else to listen to my audio setup with the printer cable first and then the DAC's stock cable. In fact, I told that person that the sound was supposed to be the same with both cables, because they are digital cables. After listening with the stock cable for less than a minute, that person said: "This one is better" I asked then: "Why is it better?" The reply was: "The other one (printer cable) has got no bass." Obviously, that was an exaggeration, but I understood what that meant. We both noticed the most obvious difference in sound between the two cables. So, now I know that despite the "ones and zeros, all must sound the same" theory, the USB cable that I use can make a difference in sound quality.
Despite having less bass quantity/impact, I liked the bass with the printer cable better than the bass with the DAC's stock cable. It is tighter and more refined. The treble sounds better, too. It is noticeably smoother (less piercing) in the printer cable. Being used to how tracks sounded with the stock cable, the passages where highs can be appreciated, sound surprisingly different (and better) with the printer cable. So, I ended up replacing my DAC's cable with the printer cable.
Knowing then, that USB cables can make a difference in sound quality, I got interested in getting another cable for my DAC. I took the time to search online to find out which cable would be the best or close to the best choice for my DAC. I did a lot of online reading and this is what I found out about USB cables for audio applications:
There is a compatibility issue between audio setups (systems) and cables. The best cable for one audio setup, could easily be far from the best for another audio setup. So, it is not unlikely that A is better than B, and B is better than C, but C is better than A!. That could happen. At the same time, it is more likely that any audio setup will sound better with a cable where more effort has been put into the making of it (and likely pricier) than it would with a simpler (and likely cheaper) cable. Taking all this into account, the good bang for the buck cables, are those cables that sound better than most of the cables that are lower in price. The better bang for the buck, are those that sound better than all of the cables that are lower in price. The best bang for the buck are those that sound better than all of the cables that are lower in price and sound better than several cables that cost much more.
Moving up the scale from a generic USB cable, the Belkin Gold is between a good and the best bang for the buck cable. There was one reviewer on Amazon.com (Marcio Small, from Brazil) that was disappointed with the Audioquest Forest because a Belkin cable sounded better than the much pricier Audioquest Forest cable. That review has now been removed from Amazon.com. But, you can do an internet search in your browser with some of the review's content and you will find a link to that review, that obviously, will not work. But, as good as the Belkin USB cable is, it is not in the audiophile category. Fortunately, you do not have to go deep (or rise $$$!) into audiophile territory to find a better or the best bang for the buck USB cable. It is the PANGEA USB-PC cable, which is made of copper and 4% silver. That is the same one that Dsnuts showed us a few days ago. Here is a post where it is said that it performed better to the listener than a cable that is ten times the price of the PANGEA cable:

Here is another post where the PANGEA cable performed well compared to cables that have a much higher price:

It would be good if you read the whole thread. It is just one page long and the Belkin cable is placed in perspective in that thread.
Here is another post just like the previous ones:

Read the whole thread, it is just one page long.
The worst reviews that I have read about that cable are like this one:
http://www.amazon.com/Pangea-Audio-cable-PCOCC-silver/product-reviews/B005AWT9IM/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1
I have not read any reviews or comments saying that another cable of similar or lower price, sounded better than this cable, something that happened with other higher priced cables.
Word of wisdom: Get the PANGEA cable. The Belkin cable is one that you will likely want to upgrade in the future. The Belkin cable would be a good temporary buy if you think that it is good to turn it into an all purpose spare USB cable, once you upgrade to a better sounding cable. But, if you are thinking of it as your main audio USB cable for years to come, it is better to buy the upgrade once and for all than buying the Belkin now and the upgrade later. Besides, the shortest length for the Belkin cable is 6ft, which is too long for the usual computer-DAC setup. Also, the shorter the cable the better the sound you will get from it. You can get the PANGEA cable in lengths between 0.5 and 5 meters. Finally, the PANGEA cable looks better and that counts, too. Here it is:
Do not get the copper + 4% silver PANGEA (USB-PC) cable confused with the pure silver PANGEA (USB-AG) cable. The pure silver cable is more expensive and there are several negative comments online regarding its sound quality. Here is the right cable:

I rest my case.
