Which USB Cable best for my new USB DAC

Hi echolane,I'm sure you find this all daunting but once through the initial process it will become easier. I notice one poster was having a dig about us recommending more expensive cables and saying for you to get a cheap one first. I'm afraid I find this a bit of a false economy as if you ever want to resell it you will only get peanuts for it. I tend to get a really good cable first and the chances of wanting to change it later are very small plus I don't see why I should break in a cable for someone else to get the benefits. Jitter was also mentioned and there are many ways of fighting that little chestnut some very expensive and some not so. The one I would recommend is a program called Fideliser Plus, what it does is shut off lots of windows programs that actually contribute a lot of jitter thereby taking an imense load off the processor and forcing the processor to just use one core on audio based programs. It works a treat and is super value for money. I find as we get older we get more and more afraid of technology and we shay away from it. I have just built a new PC for my friend and set it up for him and he has taken it up like a duck to water and he is 72 so it can be done. Good luck in your quest and if you need any help at anytime just post it up and I shall do my best to help.Jim.

Firstly, the USB cable will be a type B from your PC to a type A to the DAC.

It is Type A on the PC and Type B (generally, but not always) on the DAC.

Good to learn the connector ends are different - thanks for that bit of info!

I tend to want to use at least “better” quality on the scale of good-better-best.  Besides wirh cables becoming really expensive, I just cant afford to play in that kind of high stakes game.

Echolane, Try different USB cables before you buy. There is a chance that it won’t make any difference. Guy who made video, in the link you posted, is a little bit confused. He describes two things that might happen to digital USB signal: bits might not be recognized properly or timing jitter will convert to noise. As for the first - you need only cable with good shielding and no power wires. As for the second - there is no jitter involved at all since your DAC has asynchronous USB input, meaning that timing/clock of the data has nothing to do with timing/clock of the DAC. DAC receives data in packets (frames) at about 1kHz rate and places this data into buffer, signaling back to computer buffer under/overflow status to which computer adjusts size of the next frame. DAC takes data from this buffer at its own clock rate. The only jitter involved is internal clock jitter that is affected by the system noise. USB cable might inject some noise into the system but it is more likely dependent on you DAC sensitivity to it, cable design and not the fancy materials or high price. It is possible that you will hear difference between USB cables, but there is also possibility that you will hear none. Don’t spend a lot of money before you try. You can also investigate USB conditioners that will rebalance, reclock and possibly even add optical isolation between computer and the DAC.

(He also talks about extremely low USB 2.0 input levels and bits being not recognized properly because of electrical noise, but forgets to mention outputs levels, where high level is 2.8-3.6V. In addition it is differential)
