Now that no one reads us, I am AMAZED by the sound of the full-range Cube. Where was I these years without finding out about its existence? 😮

[@blownouttransmission5832]

its remarkable that home audio is at a level where we can hear the difference between digital signal transmission types via a youtube video .

Hello. Yes if one picks good components and experiment, amazing sound is achievable. ;)

[@9Hoots]

Coax SPDIF sounds just natural, USB sounds very edgy at the upper midrange, and Optical sounds rolled-off at the upper end, thank you for the effort.

[@manzanaresantonio]

The differences are so minimal, that even with my B&W or Grado headphones and a Good DAC, I can't barely hear any changes. They all sound great to my honest opinion.

Differences is very small. But i can say one thing your setup sounds awesome this is how music should sound.

1 technician told me about to issue of using 2 interconnects in the same sound system. The coaxial cable is supposed to be engineered as perfectly as the rca analog interconnect, as long as you would be using the coaxial with a dac amp combo, avoiding the other slight negatives that has the rca analog interconnect. I remember having testing that 10 years ago, and it is possible. So to use a PC sound correctly, one to use the Odin2 coaxial cable, with dac amp combo. I would prefer having a pellicular micro detail sound approach with the Odin2 cable, rather than a 30K$ dac amp combo for playing PC games, since i

[@sanolivo6867]

Uhh I was able to tell the changes, every time you switch to optical. It sounded more precise to my ears. I think I would have to measure the frequency response, I think a oscilloscope can give me a better idea for me to decide.

[@Gsmiler]

Reading the other comments tells you everything you need to know, we all have different tastes, we all hear differently yet each person believes the order in which they've chose is correct! 🤣

[@deepcuttabeats356]

Through my Focal Choras, the USB was the best. It sounded as if the soundstage was a bit larger. The sound was more effortless. Optical was close, but sounded a bit “harder”. Coaxial sounded the softest and soundstage more narrow.

[@VirtualHiFi]

Thank you for sharing your feedback.;)

[@deepcuttabeats356]

@@VirtualHiFi I have no idea why USB sounds better to my ears, but it does. Shouldn’t they all sound the same? Or is it because each transport is implemented differently on each device. So maybe in another device pairing, the optical may sound better than usb, or the coaxial? Moral of the story appears to be try each connection type because they may sound different and pick the best one for you.

[@quadrannilator]

​@@deepcuttabeats356 I agree that the signal chain starting from the source all the way to the receiver side is a very different electronic pathway for the same binary data (in the audio file) reaching the actual DAC chip, not to mention external factors like how each signal chain is differently impacted by changes in EMI, temperature, power supply variations, etc etc. I would say, that for better or worse, it would actually be surprising to me if there WEREN'T any changes in final sound output amongst the difference signal pathways.

[@tessie4204]

For me its USB but it all depends on the wich DAC we use and wich equalizer settings we use. So its very personal. Thanks for the video :)

[@VirtualHiFi]

thank you for sharing your comment ;)

[@D1N02]

I liked optical best, then usb, then coaxial. Through the crappy optical out of my old tv (it kept skipping)to the dac differences were hard to hear though. I think optical is always the safest choice because of galvanic isolation. Usb out of a generic pc is going to be q noise fest. What is best will depend on what you are connecting. The difference between this version of Mama this one is for you and the original is magnitudes larger though. Beth rules!

[@ДмитрийФазер-н3ъ]

1 - coax, 2 - optical, 3 - usb. Very small difference, not sure about 1 and 2 if I hear any diff)), but USB seems to me less freedom in sound, slightly "smaller"

[@VirtualHiFi]

Thank you for your comment and feedback :)

[@dylan.j.schreiner]

great taste

[@matytinman]

First and third track: differences are small. 1. Coax-SPDIF, the best 2. Optical 3. USB Coax-SPDIF and Optical have more mid frequency boost and more "body" aka analogic. Very good sound recording! Live: the difference should be much more noticeable by avoiding the conversion to AAC 192 kbps (4K videos on KZbin vs 128 kbps 1080p).

[@matytinman]

USB, the sound is more open but more "digital", with less "magic". Optical, less spatiality but more analog 👉Coxial-SPDIF, analog and spatiality. It is the winner without discussion.

[@Non-Human-Grade-Kibbles-Poison]

I've studied this topic earlier to the point of crazyness, I agree with the op order 1-2-3. It's exactly that. none of them are perfect from these 3 through. so, because of that I have limited to coax V2 nordost. If it was going to be a perfect sound like the rca analog interconnect, I would have gone for the Odin2 too here. The coax ain't worth it to max of levels, it blocks at certain aspects, the coax sound is far from as natural as the rca analog one. It feels stressed up in advances, but to the point of Odin2 not worthyness, apparently so, yes.

[@Non-Human-Grade-Kibbles-Poison]

I have used for a long time the Nordost Valhalla 2 Coax, and the audioquest diamond optical. The coax is of very so slightly better than the optical (only reachable with the Valhalla 2). After hearing the usb from youtube, I get to place it on the list too, more or less. The usb does seems to be the loser here, compared to optical and coax. It's such a gigantic bummer, since all these digital interfaces have slight problems, compared to the simply perfect RCA analog interconnect. Should I go and exchange for the Odin2 coaxial and save the furnitures that way is questionable since the coaxial sounds the less natural here, and one to suffer from it with ear fatigue. what a gigantic mess of a bummer. beside smoking a whole rent of cannabis meanwhile thinking about this tremendous unsolvable life issue. 😐

[@filipsosu]

Hi, I also have the A6ME. What you have actually tested here are the quality of the A6ME outputs and not the cables. Acusilicon femtoclocks in ME are in charge in the ME only for the USB output and that's an official info from eversolo. So of course USB is the best sounding one because coax output of the A6 is garbage. Try to put matrix spdif 2 or 3 between A6 and Weiss and go with coax to Weiss and you will be amazed how much better coax is sounding than USB directly to DAC.

[@VirtualHiFi]

Interesting thank you for sharing that ;) And who would care about that anyway since it's all 0s and 1s anyway ;)

[@thelowprofile9767]

Even if each one sounded different from the other, it doesn't necessarily mean that it is better than the other. When watching the video, one should close their eyes and tell at the end of the video which one they chose as the best.

[@bossunimportantstuff]

Thank you, the differences are clear to hear, great recording skills. But the question is why do the differences occur? My guess is that the USB send the data straight into the DAC where as optical and coaxial have additional sending and receiving circuitry that affect the sound quality. I see you have a TV on the wall. Many TV's can send audio over the USB connection and some TV's have optical outputs. It would be interesting to hear the difference between signals from the TV versus the Eversolo streamer.

[@garlys3417]

Thank you, great video and super sound. I agree, first USB the most neutral, 2nd optical and last coax.

[@VirtualHiFi]

Thank you for your comment and sharing your opinion 😆

[@danielbrrio]

For me it was the opposite. USB is uncomfortable at high frequencies, optical is more airy and coaxial is more natural, perhaps a little nasal. For me, I would go with the coax.

[@EbedTang]

Can not hear the difference clearly but i think That's about the wideness and clearness. If what i hear is true, i go for the optical.

[@louv4437]

The difference was slight but the coax had ever so slight better low end then USB was second and optical had the smallest soundstage but again it was slight.

[@ianpdavis]

Yeah same conclusion.

USB sounds better. No surprise. Optical still have that analytical cold sound no matter what the 1's and 0's people say 😊.

[@alberto3028]

Do you have a fiber optic router? 😂

[@oliivioljy9700]

In my opinion, usb gives a slightly softer and slightly fuller sound and warmth in the bass end and sounds the most natural. Coax is slightly more clinical but also slightly pleasantly soft and really good, and optical sounds very clear but does not separate three-dimensional sound elements as well as USB. More than that, the optical is such a strong, sterile, clean sound. Very good of course, but that little warmth and relaxation in the voice is completely missing. All three represent quite good cleanliness and a good end result, but require high-resolution hifi tricks that you can also locate the differences. Mediocre hifi gadgets had a price even if they were infinite, you can hardly notice any differences.

[@wegardfjeld3789]

[@wegardfjeld3789]

@@VirtualHiFi Differences between USB inputs and the 2 others on DACs are mainly the clocks, technology and how signal is handled more so then the cable 😉. Dac dependant too. On the Eversolo A6 ME LPS as a example it is very audible. Spidif/optical connection is outdated in current state.

Definitivamente se Escucha Mejor con el Cable USB luego el Óptico y por último el Coaxial con Ruido

[@VirtualHiFi]

[@manardh7387]

It's what I have heard at times. The USB distorts the sound in a way the sibilant distractions sometimes gets masks with the apparent higher frequency advantage. The optical can be better and in this case its close between optical and coax. I hope that doesn't mean "coax TV cable". SPDIF can be quite good with a better grade cable. And then the close second place goes to optical. It's always easy on the brain and rounded. You must volume adjust for optical, better louder to hear the advantage. Again the optical quality cable has proven to matter. Thanks for the compare.

[@kobush18]

Sorry man but the test is not correct, what you test is not the cable only but the whole pass it's going through, meaning the electronics involved both on the receiver side and transmitter side and their influence on the sound. The cable is on part of three transmitter cables and receiver, you can't isolate and say it's the cable fault,it may be the one of the others fault , it's like a formula in mathematics with 3 variables , in other systems with other implementation of transmitter/receiver electronics the end result might be different, this result is unique to you system ( usually usb is the better method but not always)

[@VirtualHiFi]

Since you mention that I totally agree. I. A future test ill try to remember and address it more. The concept is what is The difference in sound if any and yes it's more not how the cable sound but how will the system sound using that particular cable ;)

@@wegardfjeld3789 It's not 1's and 0's. The signal going through the cable is analog. Pure digital information can't be sent through a cable. Its an analog representation of the digital signal. The same things that effect other types of analog signal transfer can effect the "digital" cable as well. As for a blind test, its a complete waste of time. I can tell you what the outcome will be before you start. If the test shows there is no difference between the cables its accepted without question. If the test shows differences between the cables, it won't be accepted under any circumstances, no matter how well done it is. This whole issue has never been about cables. For some people its about winning an argument regardless of facts. For others its about building a youtube channel by telling them what they want to hear and calling it science. The next time someone asks you for a blind test, say this. "Can you reference a single, well done blind test, conducted by a reputable source that meets a standard you will accept, on any piece of high end audio equipment ever made?". After all these decades, they have yet to do a single test or provide one from a reputable source.

[@Negatywny2]

yes, you know, there is a technology that allows you to losslessly transmit a digital signal over a distance of hundreds of thousands of kilometers (from a server room in Hong Kong to your home) simultaneously using hundreds of different and cheapest possible cables, through hundreds of amplifiers and hundreds of various network devices, while simultaneously, for example, repeatedly converting the signal from the electrical to optical - but there is no technology that allows you to losslessly send this signal from your streamer to a DAC half a meter away from it :)

[@alberto3028]

👌

[@alberto3028]

Hahaha, you nailed it, and you explained it with quite clever irony. Plus, the people claiming there are differences are probably connected via WiFi to a router that operates on fiber optics! Haha, the next test should be done to see if there are differences with an ADSL modem or fiber optics, as well as if there are distinctions between playing CD-quality via WiFi or USB. 😂 Ignorance is quite daring; people are unaware of what the buffer is, CRC corrections, and, most importantly, that there is no jitter because the clock is internal to the DAC itself and not from the source.

[@quadrannilator]

While your comment is probably aimed at the crazy belief systems people have in the hobby, it also points out a very clear irony about electronics, that the moment a signal goes from the digital domain into the analog, the word lossless loses meaning and hundreds of little factors change the analog waveform that those final few metres and nanometers matter more than the thousands of kilometers that digital signal has passed through before the sound reaches your ears...

[@Negatywny2]

it's cute, but the signal between the streamer and the DAC is still digital, just like when it crossed the Atlantic@@quadrannilator

[@VirtualHiFi]

I agree. There should be no difference at all. I get that point. Ones and zeros remain the same and are decoded to analog later on and the same should happen. On the other hand I don't care about the cables and I approached the test with open mind and felt like there are slight differences. Yes it can be a placebo I will not bet against it, but 0 and 1 is a fact, but if you can hear the difference between one and other digital cables, that can be possible too since the measuring device(brain) was preprogramed by all the opinions the testing person read / heard and it impacts the perception, and brain can make the difference real (for this person). I do recordings because i find it more objective. I also share my opinion since many people are asking for that as well, but listening to some videos make the difference absolute evident hence worth fighting for. With the digital cables the difference if any is slight and while I would not buy some uber expensive cables, if one have various cables lying around or can but them without an impact on the budget, I'd say go ahead, if one can hear the difference, it is real at least for the person listening ;)

Thank you for your comment. Indeed this is interesting since I had few experiences with USB cables where I'd say I'd definitely hear the difference. I know the theory and I never claimed that you have to pay extra money for super 10000$ USB cables, coax and optical are some standard 20$ market cables (since there is no difference anyway ;) I test all cables to check if there is a difference and even if it's only placebo, placebo also brings the difference so even if according to the theory it does not change the sound of the setup, but changes the measurement system (human brain) it changed the sound perception after all ;)
