Will a quality USB cable make a difference....

The Diamond usb cable is so much better ,it is across the board better than the carbon usb cable. The top end air, the transparently and better defined bass are easily distinguished differences. Don’t let anybody kid you there is no difference among usb cables. The difference to me is just like all the rest of the cables. They all sound different.

Sorry, but it's just not possible. Keeping it simple, USB is a digital data transport bus, not an analog port. All it moves in the data path is 0s and 1s. If a different USB cable results in a change anywhere downstream then you have a major problem somewhere in your system. I know that you think that you are hearing what you say that you think you are hearing, but all of my 30+ years experience in the physical sciences, data collection and computer systems design leads me to believe otherwise.

Br3098... please, please, please speak from audio experience. i.e. actually using different USB cables on a quality DAC with a quality computer such as the MacMini.

Give it a try... actually build some real listening experience with this equipment and cabling... and then come back to us with your listening experience on your own system, with your own DAC, your own computer, and your own music... not your book learning and theory derived thereof.

I respect learning from the academy. I am a product of it and an active member of it myself. But it has its limits, and this is one.

If I sound annoyed, I am.

I am frankly so tired of "authorities" who have not taken the time to gain their own audio experience misleading newbies with the "truthiness" of their book learning and university degrees on chat forums such as this one and in other places.

Listening experience matters. This is not an article of belief or faith as in your statement >>leads me to believe otherwise<<.

:) listening,

I have done exactly what you suggest Istanbulu and I could turn this arround on you. I agree with Br3098! Not just because of some education or the science of electronics but from experiance. I am not going to argue with what you say you hear, just that for most "newbies", as you call them, they are MUCH better off putting their money in the best equipment they can afford in the body of their system! Body= speakers, amp, line stage and dac. If I sound annoyed, I am.... for at one time I was a newbie and listen to such gibberish. If a usb cable makes a real difference it is so limited to my ears I can not hear it. Now that is not to say that if your cable has a loose connection or is so poorly made it may not hinder the transpher of digital information. It does not take an expenssive cable to complete this task. But, as long as the digital info is transphered completly, the sound quality is determind by the dac/clock conversion, the line stage's ability to magnify and transpher, without any added harshness or denigration to the amps, which must do the same for the speakers. Spend your money where you wish. It is your money. IN MY OPINION, Not on digital cables. Take it or leave it!

"Sorry, but it's just not possible. Keeping it simple, USB is a digital data transport bus, not an analog port. All it moves in the data path is 0s and 1s."

I'm afraid that this is a tired argument. I've read the same argumant dozens of times on the forums. This shows a misunderstanding of the difference in audio streaming and other data transfers.

This is real-time. All other transfers from a computer are not real-time, except maybe some video.

Because it is real-time, it is subject to timing variations. These timing variations can have an impact on the USB interface, ranging from direct jitter affects, power effects, grounding effects, RFI effects and transmission-line effects.
