USB cable recommendation

@audphile1

You’ve offered a lot of opinions about ASR, Amir, “minions”, and the price of other people’s DACs, but none of that actually addresses the technical question at hand.  

If a USB cable truly changes tone, detail, or presentation, then those changes must originate at the DAC output. That’s the only place they can become audible. And if the DAC output changes, it can be measured. If it can’t be measured, then the claim remains subjective,.  

Dismissing measurements, dismissing blind testing, and dismissing engineering doesn’t strengthen your argument — it just removes the tools that would allow your claims to be verified.  

I’m not basing my view on the price of anyone’s equipment. I’m basing it on how USB audio transmission actually works: packet‑based data, error correction, retries, and the DAC’s own internal clocking. If you have evidence that contradicts that, you know, measurements, controlled tests, or published data, I’m genuinely open to reading it.  

But personal impressions, especially in sighted conditions, aren’t a substitute for evidence. Confidence in what we hear is not the same as proof of what is happening.  

When you have something more concrete than insults toward ASR or assumptions about other people’s systems, I’ll be glad to continue the dialogue but something tells me that discussion is not what you want.

Digital signal that traverses via USB is encapsulated in an anslog signal and is represented as voltage fluctuations. USB is made of some sort of alloy, be it copper or silver, the only method to exchange data is voltage fluctuations.

Just recieved a sense check from an ex Sony colleague who was involved in the development of the Sony SCD1 at Kita Kanto, he now lives near Kosai and is retired but still as sharp as a tack!

"Hi G San

The poster is confusing the physical layer of USB with the audio domain. Yes, USB uses voltage transitions to represent 1s and 0s but that does not make the audio signal analog and it does not give the cable the ability to change tone, detail, warmth, air, or anything else.

As you correctly pointed out in your email G san, Voltage transitions carry data, not music. The DAC does not reconstruct audio from the shape of the voltage waveform on the USB cable. It reconstructs audio from decoded packets after error checking, buffering, packet reassembly, reclocking,  jitter isolation and power isolation.

The USB cable never carries a continuous audio waveform. It carries encoded packets. So when someone says USB is analog because it uses voltage fluctuations, they are making the same mistake as saying a hard drive is analog because the bits are stored as magnetic polarity".................

So all that's left to negatively upset the apple cart is Noise, that is easily solved by shielding most decently made still inexpensive cables do this more than adequately, some double or triple shield, recognizing external noise as the only real influence.

ASR or assumptions about other people’s systems,
 

@nubiann Please, as if ASR doesn’t say the same about members in this forum.  

Though your posts are thoughtful they are also in a “USB Recommendation” thread. I know we all want to be saviors at one point or another, but it’s odd when the OP is simply wanting recommendations and members try to argue that there’s no difference is USB cables.

Some will argue, myself included, that there should at least be decorum to respect the OP’s question to avoid derailed threads such as this. Others will differ in opinion so I’ll leave this as “food for thought.”

Point taken and well received It did drift somewhat. I should have transferred the response to a more appropriate section especially when responding to certain person. I’ll say no more on this subject. Thank you for pointing this out.
