YesI'd be interested to know if Amirm has tried to compare cables for analog transmission
Hello, Here is a video with a rigorous demonstration showing the absence of any influence of the cable quality for a digital signal transmission.
I'd be interested to know if Amirm has tried to compare cables for analog transmission. The role of more or less careful installation, cable crossing and cable quality (price). Thank you for your comments Hans Wolfgang Spiess from France

There are so many fraudulent reviewers on YouTube, they are just like the rags such as WhatHiFi, Stereophile and all the others who are paid by these manufacturers to survive!A new argument has developed that transmission of digital audio is really analog. And for this reason, everything digital can be subject to audible difference from digital audio cables to digital output of streamers. This was emphasizes in a video by Darko Audio saying this explains his subjective opinion of streamers sounding different. I address this in this video and how there is some validity in what he says but his end conclusions are incorrect:
Doubt it!Hans Wolfgans Spiess of Max Planck Institute by any chance?
Hello,Hans Wolfgans Spiess of the Max Planck Institute, by any chance?
Very good video and very good work. For others who have not watched it, he shows that a cheap USB cable going through a Toslink loopback on RME creates bit-exact output. He shows the same with S/PDIF and I^C. He also goes thorough explaining that if there were bit errors, they would be random and not create the differences audiophiles talk about.Hello, Here is a video with a rigorous demonstration showing the absence of any influence of the cable quality for a digital signal transmission.

That’s why Nordost charges so much money for their cables do you get the extra noiseVery good video and very good work.

On your question, yes, I have reviewed a number of analog cables and none show any improvements and a few actually are more susceptible to noise than cheap cables. Key thing to remember is that as the simplest part of your electronics, your cable has far higher bandwidth, far lower noise and much less distortion than your complex audio gear. For this reason, it cannot possibly make a real difference. Measurements and null tests with music show the same. In this review, I show how the cheapest, oldest, crappiest RCA cable is still transparent to the source: https://www.audiosciencereview.com/...ton-rca-cable-review-ultra-cheap-cable.33473/
Above shows that the cable has the same performance as having no cable!
Here is a review of Nordost speaker cable compared to generic: https://www.audiosciencereview.com/...ost-superflatline-speaker-cable-review.45615/
It actually picks up more noise than the generic cable. But otherwise has flat bandwidth to 200 kHz and beyond, just like the cheap cable:
There are many more tests like this.
That said, if work hard, you can find cables that make a difference like too thin of a speaker cable, or one with poor quality. Spend a few dollars more and you are assured transparency.
Some possibilities:As a computer science engineer I totally agree with the fact that digital audio is only 0 and 1 and the disruption of digital square waves do not affect the analogue audio section of the streamer/dac, but I cannot understand how there are stil differences between different streamers (when using them to stream digital only). I tried using my receiver's internal streamer and then used an external streamer connected to my receiver through hdmi and the external streamer sounds different. the soundstage is around 5-10% wider and the separation of tones is slightly better. The differences are pretty small, but never the less, there is a difference
What are the properties which are affecting the sound?
I did the test using Pure Direct mode in the denon receiver, so no dsp involved.Some possibilities:
- Level matching if there is any digital volume control or other digital manipulation in any of the devices.
- Different DSP being applied between your receivers internal streamer versus the HDMI input.
- Different masters if you are streaming from different files/servers/services.
- Alternatively - cognitive bias - if you are not testing blind and controlled.
Not sure what manipulation will be done by the external streamer to format the stream for HDMI.I did the test using Pure Direct mode in the denon receiver, so no dsp involved.
Measuing in the audio domain is not accurate enough if adjustment is needed. Needs to be measured with a test tone using a volt meter at the speaker terminals. Even a tiny difference that you won't hear as a volume change can alter the perceived quality.volume was exactly the same (though measured in decibels by an app on my phone)
A step in the right direction - now you need to confirm you can tell which is which at least 9 out of 10 times - no retrys - and with absolutely no tells (such as a different click sound for the select buttons etc - and if you are opening your eyes - no visual cues either. Also no interaction with your daughter so she can't give any subconscious cues.My daughter changed the inputs while I'm blind folded, and still I could hear the differences.
Since the sounds come out of the the same receiver used as a preamp, the volumes match exactly, no adjustment was needed. I did confirm the differences 10 out of 10, the difference in soundstage width is audible and easily detected. The streamer is a DMP A6 master Edition.Not sure what manipulation will be done by the external streamer to format the stream for HDMI.

Well then the only two things I can think of you could now do to work out what is going on would be:Since the sounds come out of the the same receiver used as a preamp, the volumes match exactly, no adjustment was needed. I did confirm the differences 10 out of 10, the difference in soundstage width is audible and easily detected. The streamer is a DMP A6 master Edition.
And on a similar subject, after reading a lot of measurements in this site lately (and learning a lot about manufacturer's BS thanks to the great information provided in these forums) I noticed that a lot of R2R dacs have average measurements but still when comparing my Gustard R26 dac to the Eversolo's own dac (which measures a lot better). the Gustard just sounds better (and will do so in every blind test I tried going in to the same preamp and power-amp, volume matched of course), the bass is more punchier and accurate and voices are more dense and pulpable by pretty much, Soundstage is a bit more 3d consisting of a bit more depth (more separation in the stage, more air) . Is this the harmonic distortions who give us a sense of depth and more 3d perception?
