It sure helps the one posting audible difference claim on forums and it sure helps those trying to sell audio electronics if there is real audible difference.
Hi Andrew.
In my experience USB cables can/do cause 'signature'.
I also find that the pro format Dante is sensitive to cabling, as proven on two recent shows.

What good does personal anecdote on USB cable do for others on the other side of computer screen?
It confirms that more-than-zero people have performed a listening test, and in that test, found a difference.
To my surprise, many people who say "X is negligible" have never bothered to listen to X. Which means they are lazy blowhards.

Proven? Got a link?
You know, in any reasonable system, the conversion clock sits next to the converter and the USB or AES67, Dante, etc. data does not even enter the "critical" domain until it is clocked out of the receiver by the conversion clock. You can pass this data through a bucket of mud if you want. It will either arrive at the receiver intact or not. It is 100% asynchronous. Yes, I am aware there are low-end USB receivers that operate in synchronous / isochronous modes, I will ignore them because they don't belong in a "high-end" device.
I really should know better than to reply to someone who thinks listening to equipment with leaded solder can be harmful. Of course you would find USB cables make a difference, since you can hear solder.

Or maybe they aren't daft enough to need to test what their PC demonstrates billions of times every second to them every day by virtue of its very operation?
Why do we need to entertain stupid?
Seems to be a poetry appreciation chair (???) from the hitchhiker's guide to the galaxy.
If such step is considered "test", then just by the nature of people having sound playback system, they all performed listening test.
You've taken a survey to know that many people did or didn't do that? When and where was the survey taken?
Your response on DBT is strangely similar to other posters who sell audio electronics which brings up a question, what do you sell or do you have business ties do those who sell audio electronics?
Can you post a link to that proof or share the location of that info?
Yes, and
Yes....in other words such 'experts' obediently swallow information that is presented to them in written, video or oral forms.
When presented with personal accounts that go against these 'belief systems' extraordinary attack of 'new' information ensues. Strange, very strange behaviour IMHO.

You are the prosecutor. The burden of proof is yours.
Oh, Lord ! Hifi equipments are just tools to listen to music. Listening music is an entertainment. Why the hell would you turn a pleasure into an inquisition trial ? Are not you sensitive to the ridiculousness of the situation ?

I well understand line interface and asynchronus operations. I have two short USB A M-F extension cables that are 'same but different' and when fitted to PC end of existing USB soundcard or dac cause two distinct and readily identifiable system sounds.....anecdotal findings of several listeners/trialists in addition to myself. In recent weeks I have run two sets of experiments on a particular modern digital PA system with unequivocal subjective (positive) results. Included in last Sat night's experiments was clipping a particular filter around the 'digital snake' Ethernet cable by the owner of the system who after several OTF A/B comparisons reported very favourably as did I. I also now have measurements and difference signal proofs of changes in dynamic excess noise of USB soundcard itself in loopback rec mode. Next stage is to measure loopback changes in typical consumer amplifier excess noise and then the complete system all the way to the speaker driver terminals.
Did you ever try passing USB signal 'through a bucket of mud' ?. Did you ever experiment with solder alloys ?. If so I am interested to hear of the test conditions and your findings ?.

Following my listening test, the SQ is clearly influenced by the moon phases. During the full moon phase (and with a plus for the February super moon) the sound is more rounded and cohesive, while during the new moon, the sound is edgy with unpleasant corners.
This makes more-than-zero people that have performed a listening test, and in that test, found a difference.
To my surprise, many people who say “the moon phase effect is negligible” have never bothered to listen to the moon phase effect. Which means they are lazy blowhards.
So there 😀. BTW, the data about these listening tests is proprietary and confidential, so please don’t ask about.
I thought I was responding to what forum posters decided to post on their own. When and where did I turn someone's music listening entertainment into inquisition trial?
I have noted that complementary jfets from Linear Systems seem difficult to impossible to get, even through DIY audio. I am sorry about this, and I can only hope that things get better. Most of my designs rely on complementary differential jfets for the input stage, but my manufacturers have sufficient stocks to go forward with my designs without any delay. I hope that alternative topologies serve well enough that you can still DIY without completely resorting to IC's for every application. I spoke briefly with the president of Linear Systems this last Sat. night, but it was too noisy to do more than greet each other. I do hope that Linear Systems will free more jfets for DIY. Apparently they are doing OK, from my sources.
Good satire!
However, while I find it very difficult to accept some of what Dan (Max) says at times, KSTR who seems to be a real engineer did report doing some research showing that USB powered dac reproduction can be influenced by where data is stored in a disk drive or other media. For similar types of reasons, perhaps cables could be implicated. Also, depending on how dacs are connected to other equipment, ground loops can occur. Don't know what effects cables might have, but I am convinced that things like well-designed power conditioners can have a very significant effect on sound quality at least in systems that don't use balanced interconnections. The power conditioners may mostly work in that particular respect by increasing ground impedance between audio system devices, but not to earth ground. I think such considerations may be part of what Jakob2 was referring to when he said that the non-golden ears forgot some EM theory. Not all of the foregoing was re one particular issue, just some various thoughts following some of today's discussions.
