This is utterly hilarious. Is it satire? The idea that an Ethernet switch could have any impact on listening other than maybe some weirdness with a ground loop or whatnot is absurd. If an audiophile were really truly worried about Ethernet they should use fibre, and then they’ll never have to worry about anything.

No ground loops in Ethernet. The signalling wires are driven through transformers, isolating them from ground to improve noise immunity.

Latency maybe, but the article doesn't talk about it, and this is typically solved the same way it is inside your computer when feeding the sound card: deliver too much info then wait. The real time delivery constraints that you can patch into the Ethernet stack on Linux are only necessary for reducing roundtrip time.

If only USB did the same. Would be a big improvement to USB connected instruments and audio interfaces. A man can dream.

Indeed. I had to get a USB ground loop eliminator in order to run my Line6 Helix connected to the computer. Now with USB-C-only computers, it's Helix -> cable -> ground loop eliminator -> adapter -> computer. Without the need for it, I'd have just replaced the USB-A cable with a USB-C one and connect directly to the computer.

technically you can ground-loop passive high powered PoE gigabit ethernet (like for 85W radios or big beefy heated pan/tilt/zoom cameras), but that's not the scenario here.

Not defending this BS by any means, but certain cables have metallic connectors which I believe are connected to the cable's shielding jacket, and if the ports on either side are metal they are probably connected (maybe unintentionally though physical contact with the chassis) to the device's ground, so wouldn't that create a conductive path for interference?

When made properly this is only supposed to be on one end. If it's on both you do get a loop, but the disruption to the signalling doesn't manifest as audio noise in the way the website seems to be speaking of.

This is a novel idea ! Sell bullshit to people who think of themselves as audiophiles. Surely no one has done that before.

It has to be? The albums look chosen to represent a certain strain of aging hipster that doesn’t realize the world has passed them by. If this isn’t satire, the author is astoundingly self-unaware…

Fibre has its own challenges -- crystalline structure, IoR homogeneity, and polarization effects can affect the entire audio spectrum. I wish I could say it's better, but ultimately ju/st a different game.

this assumes you're transmitting analog data through fiber.

fiber as an ethernet link is packetized and has error correction. 1Gbps and 10Gbps stuff is just OOK blinking LED on and off. Pretty hard to screw up unless you have a chipped ferrule/facing, dirt on the fiber, or dirt in the connectors.

Someday we will invent a transmission medium which preserves the fidelity of satire

Funniest comment I've read in quite some time. Well done

but which FEC is best suited for satire?

I'm going to say turbo product codes

can we maintain high fidelity satire close to the shannon limit? what do the varying code rate waterfall curves look like for satire FEC on modern equipment?

> which FEC is best suited for satire

The best I can think of is Hamming codes, because "hamming it up", but improvements would be welcome.

In the times that I used forums with phpBB and SMF I really liked that I could select the font that I wanted to use, using Comic Sans is a nice way to let people understand that you are using the satire.

I'm not sure it's satire, but it certainly hits the mark. I do wish there was even a hint of basic physics in there, anywhere.

I can see the logic behind a properly isolated switch - for example, I have optical everything as my amplifier has a terrible habit of turning switching power supplies into chainsaw noises. Anywhere I can isolate shared noise is a win. But that's achieved with amazonbasics toslink cables, not .. magical pixie dust, or whatever these guys are selling.

The reviews of the music they tested are great and could both be parody as well as what they probably are, namely the dellusional ramblings of someone who got swindled:

"Via the Ethernet Switch UEF, we have a much more defined and explosive brass section. You get the proper metallic blast and blatt without strain. The piano is now wonderfully fleshed out with plenty of timbral purity and proper weight. High hat cymbals have never sounded better. Exciting stuff!"

"When engaging the Ethernet Switch UEF, your room boundaries will evaporate in all directions. The band is now in the venue with you. The bongos are unleashed with additional color and tone and with a bottom end wallop that might just startle you. Goose bump city!"

I don't believe they were swindled - these review sites would most likely be in on it and get the units for free (or on loan, but given the true cost of one of these I don't believe it's even worth the logistics of shipping it back).

Good point, so even worse, they are scamming people knowingly.

I second the incredulity in every other comment here, but the bit that really struck me was the aluminum chassis reinforced with carbon fiber to _dampen vibration and resonance_. In an ethernet switch. What?

I guess, if I had to stretch to say something nice, it's good that people like the author exist so that some engineers get to have a bit of fun designing a boring old switch with a no-compromises budget.

EDIT: their website (the maker, not the reviewer) is pure (oxygen free, directional) gold. They have a ten thousand dollar power cord with extra little plugs on it that you can attach to something called a carbon fiber tuning module to "voice your system."

Basic carbon fiber plate in a few mm thickness is actually really cheap now, you can get custom cut quadcopter frames (with all of the CNC work included) for $40 to $50.

"Audiophile" products get me so mad, I don't even want to look at them to mock them. It's blatant anti-science, willful ignorance. To the chagrin of people's urge to keep optimizing, digital audio has been solved decades ago: CD audio can perfectly represent audio containing tones up to 22kHz, with a 96dB signal to noise ratio. Those are both figures that seem to exceed the hearing of even the best listener on earth.

For studio use, 24 bits offer some benefits for editing, but not because it sounds better, because we cannot hear better. Instead, if you mix audio it's useful to have some headroom over the dynamic range of your music (headroom you cannot hear), before you mix it back down to 16 bits for listening. Think about pasting pictures into a bigger canvas before cutting it back down.

Things like 96kHz or even 192kHz audio can actually be harmful for listening: Not because you can fundamentally hear a difference (you can't), but because if you have any nonlinearities in your audio playback chain, those inaudible frequencies above ~20kHz will cause intermodulation distortion in your audible range. Congrats, you've taken some useless crap over your hearing range and reflected it back as ugly crap into your hearing range.

Anyone who has invested time into understanding Fourier transforms and digital sampling on a fundamental mathematical level realizes that, and just gets angry at the lies. The Fourier transform and the sampling theorem don't know what an "open sound stage" or an "airier voice" is, if you think changes in sample rates and jitter translate into such human concepts instead of plain noise, you live in some phantasy non-physical world.

What is not solved is speakers and room acoustics. That remains notoriously hard, because a room easily can (and most often does) reflect parts of the spectrum such that it cancels itself out. No amount of equalizing can fix that (it's mathematically impossible), you need to change your room or speaker arrangement.

If you want to optimize audio, nerd out about that. Or if you absolute must, argue about lossy encoding formats (e.g. AAC vs. MP3) and bitrate. There is much less hard math in your way there, as they strongly rely on psychoacoustics. But anyone who claims that they hear a difference with 192kHz (on a provably linear audio chain) or an "audiophile Ethernet switch" shows that they're talking bullshit to begin with, so why would I trust their opinion on some potential real difference.

While I agree 110% with everything you've said here, I think we should be careful to not rule out the possibility that our sensation of "hearing" may involve parts of the body ouside the ear. For example, I think it's a long shot, but there is some vague possibility that supersonic frequencies may be detectable by other parts of the body. I would prefer to not be in the group laughed at in 110 years from now: "back in the 21st century, those idiots thought that we only experienced sound through our ears".

That said this product and audiophilia in general is just pure unadulterated BS.

You've definitely got a point. But that ~20kHz figure to my knowledge was not just determined by "can the ear hear this" but by "can the person hear a difference". But yeah, theoretically, it's possible that all that science was only conducted with, say, headphones.

Like with all things science, everything is only falsifiable, never 100% provable. But yeah, I think we're indeed on the same page, the claims that audiophiles make are often falsified already. Or make so little sense that it's akin to "eating an apple in the morning shifts Helium's absorption spectrum by a few nm". You can attempt (and succeed) to falsify that, but it's such a waste of time and energy...

> our sensation of "hearing" may involve parts of the body ouside the ear.

It's definitely possible to tell the difference between the quality of audio from a shitty subwoofer ($50) vs something that costs $200... Not so much audio as perceived by eardrum but perceptible vibration felt by the body. The cheap one also is likely to rattle its own chassis and feet and vibrate on whatever floor you've placed it on.

And nobody is disputing that. As said, you want to focus on optimizing audio, optimize your room, your speakers, your headphones etc... there is solid and well understood math behind speaker and room acoustic models.

Absolutely agreed... I'm in the market segment of having a $500 onkyo home theater receiver and a basic 5.1 speaker set (anything else would be a waste in a small condo living room), anything beyond that sees diminishing returns fairly quickly.

It can very well be that the sensation of "hearing" includes the placebo effect - spending insane amounts of money on an audio system that you perceive to be superior will make you believe the sound quality is better.

Of course, the answer here is proper education as opposed to selling overpriced snake oil.

Good point, I can totally imagine that this is what happens, and agree with what the answer should be.

And the moment someone presents a scientific experiment to show a difference, I'll consider it. I don't need a mechanism, I don't need an explanation, just a control group and an experimental group of visually-identical equipment, double-blind procedure, and a statistically meaningful ability for the listener to tell which is which.

Many years ago, I came across a very basic description of how digital anything worked. The key concept, which at the time was like a bullet between the eyes, was/is that all digital systems are fundamentally binary, they recognize the existence of noise in electrical signals, but represent 0/1 with two values that differ by orders of magnitude than the noise floor.

So, in a 5V system, zero is represented by 0V, and one by 5V. And sure enough, if you could look in enough detail at the voltages, you'd find that sometimes the zero was actual 0.001V and the one was actually 4.912881V.

The whole point of digital is that THE NOISE DOESN'T MATTER. Even in the presence of those fluctuations (which are real), the system sees only zeroes and ones, and everything is perfect, always.

Please don't be the modern EE who tells me that this is how things used to work, and it's not true anymore :)

> Please don't be the modern EE who tells me that this is how things used to work, and it's not true anymore :)

Things don't work like that any more in e.g. QAM [1] and multi-level [2] (DLC/TLC/QLC/PLC) flash storage.

It’s way cooler than that. Sit back and watch the master explain it: https://youtu.be/eq5YpKHXJDM

https://xkcd.com/670/

(and little nit: there's more plusses than just eliminating noise. For example, multiplexing)

How about an EE from the nineties? It never worked like that :) Logic one and zero are represented by voltage ranges. There are safety margins everywhere.

ECL is a fun one with minus ~5V supply, and minus 1.3V switching threshold.

I've seen a gold plated audiophile TOSLINK cable before. Which is actually a fat multimode optical connector. But the part you pushed into the socket sure was shiny!

edit: I found it again! https://www.amazon.com/FosPower-Toslink-Digital-Connectors-S...

At least the price is normal. I'm ok with 6 euro for a one meter TOS link cable. Nice touch with the "can't lose those" protective tip covers, I really miss that when moving stuff around.

For what it is worth, here is the actual product page: https://www.synergisticresearch.com/accessories/ethernet-swi...

I wonder if it crossed any of these reviewers minds that the audio they listened to traversed countless switches, network routers, fiber amplifiers and who knows what else before it ever hit that switch.

I have zero clue who buys this stuff. Perhaps I'm in the wrong business!

You mean you would stream your music instead of having local flac files?! You audio peasent!

How did you obtain your 24bit 96kHz flac files without them passing through non-audiophile networking kit?

In some sense, it doesn't surprise me that there's some market for this. For the older audiophile who doesn't understand digital music or networking, their only analog is.. analog. :-)

So if you look at the setup with "vinyl goggles", where upgrading your stylus or pre-amp or cartridge _does_ have some impact to audio quality - since the physical diamond or sound chambre can vary - you can see how someone without any IT knowledge could conclude that, likewise, upgrading the devices in the "signal path" (network) for digital music would make an impact.

Now like, obviously that's wrong, but if someone is willing to pay you $2000 for a Realtek switch in a fancy case.. Clearly the market will oblige!

Ah, the perfect companion for a NAS with audiophile-grade SSD storage

Don't forget to grab a few $2,995 Ethernet cables!

https://www.synergisticresearch.com/cables/galileo-sx/galile...

The description of those sure is something:

Galileo SX Ethernet cables were designed around a brand new UEF Filter featuring Graphene and a special UEF Tech first developed for our award winning Blue Fuses to eliminate digital noise through an inductive process that takes place outside the signal path. UEF Graphene Shielding is now applied in a new Matrix Grid pattern for a striking lowering of your system’s overall noise floor so you hear detail and dynamics in the most holographic soundscape of any Ethernet cable in Synergistic Research history. We upgraded the UEF Ground Plane with new UEF Blue Fuse technology and treated the entire cable to a new UEF Blue Fuse treatment that both increases overall cable performance as it lowers the time necessary for cable burn in. Lastly the outer shield of the cable can be attached to ground with an included ground plug or can be attached to an optional SR Passive Ground Block or our SR Active Ground Block for a dramatic increase in overall system performance. If fail to recognize the superiority of these cables you are giving in to Them and their blasphemous ways which doom us all to inhuman toil for the One whose Name cannot be expressed in the Basic Multilingual Plane, he comes. And with new Gold and Silver UEF Tuning Circuits that change the yin and yang of the digital cable from detailed to liquid pain extinguishing the voices of man from the mortal sphere you can custom match them to your system and taste or try them without, the choice is yours.

I fed that into a neural network based text generator and got something that is no more or less sensible and logical. Next step: fully automated audiophile marketing copy generation?

===============

And if you are a system builder and want to make sure you're in the right class, let's talk about the final piece. We went back to the drawing board and developed an outer jacket and inner shield made from unbreakable material with customizable applications. With these exceptional cables we assure that your system will stand the test of time and will also stand up to the power of the Graphene RF head stage.

Galileo SX Ethernet Cable Features

1)High Strength Diamond Strand Spliced Cable:

Some audiophiles are used to spending thousands on cabling and power cleaning and it does make a difference if $100k has already been spent on the gear. So when presented with a switch like this it makes sense to them. But they are snakeoil. One thing that these things claim is jitter reduction - because jitter was an issue on the original USB devices using synchronous protocol. But try to explain that any kit they have is already buffering ethernet because it is impossible to do otherwise, and you'll just hit a brick wall. Better to drop $2k on this, and another $10k on special ethernet cables, just to be safe!

Hang out on a website devoted to high end audio, like Meridian [1], and you'll see half the people starting threads about some new $10k cable they bought, and the other half studiously avoiding telling them they are wasting their money. Just don't get involved.

> it does make a difference if $100k has already been spent on the gear.

That sounds like a sunk cost fallacy, why does it matter how much was spent? It should be the other way around where "clean power" makes a noticeable difference with cheap playback equipment with flimsy filtering capacitors in their power supplies. So-called "audiophile" equipment of boat-anchor weight should not need "clean power", that should be handled by the power supply.

The whole "audiophile" scene is rife with mass-delusion, they fall for the same scams as those who e.g. buy "amulets for protection against evil spirits". Neither of these do anything but both may feel better by having them. The "audiophile" may get the same satisfaction from listening to whatever he plays as whatever random person does listening to his or her music using whatever equipment they have at hand. The difference is that the random person did not have to pay a scammer to achieve satisfaction. The same was true for the "audiophile" before he fell into the trap but now he's lost that ability.

I have a hot take on this: Sound only exists inside your head, so if you convince yourself something sounds better because you paid a $shitton for it, then for all practical purposes it DOES sound better.

You're paying top dollar for a placebo effect, but it's every bit as real as "sound" is.

Absolutely.. Currently working with a new HD audio codec and although I know it’s nonsense, it sounds and feels better than ever at times, in fact I can relate to his description of the clarity with his new gadget.. A simple 3 minute ABX test tells me I’m smoking crack and 1:1 normality is once again restored..

Unless you're actively thinking about how awesome your equipment is the entire time you listen, I don't think placebo is a very useful improvement.

And more accurate reproduction that enables you to hear everything in the recording is not subjective either. (And if you want certain equalizer settings you can always do that yourself on top of quality hardware.)

You can extend this analysis further. The reason that audiophiles listen to music is for enjoyment. Thus, if they get enjoyment from paying $gazillions for a cable, then it is money well spent.

What would distinguish an ethernet switch "for audiophiles" vs a regular ethernet switch?

This has the same feel to it that those green magic markers they sold to audiophiles. You were supposed to use the markers on the edges of CDs to make the data reads richer and more vibrant and warm or some such hogwash.

I'm also reminded of "directional" audio cables, and the "DiscWasher" scam from the 70s, although heaven knows, LPs really needed help.

> What would distinguish an ethernet switch "for audiophiles" vs a regular ethernet switch?

price?

And a homemade power cable

I had a Dishwasher back in the day, never knew it was meant to improve sound quality; I just liked to use it to remove dust from my LPs. Plus it was a fun part of the Tea Ceremony.

Ha ha you make joke.

DiscWasher was a popular LP cleaner in the 1970s. There was a fibrous cleaning pad attached to a handle, and some special fluid that came in a small eyedrops-style squeeze bottle. The fluid was the expensive part, $5 for one or two fluid ounces, quite expensive for the day. You'd carefully squeeze out a drop of magic fluid on the cleaning pad, and while your LP was spinning, let the cleaning pad drag over the surface of the LP.

Turns out the $5/oz ($40 a cup!) special DiscWasher fluid was distilled water. Lawsuits and hilarity followed!

This epic tale of audiophile gullibility is not even on the Internet, it appears. The past is dead.

Oh I owned one. Never knew the contents of the squeeze bottle. The brush itself was well made, and seemed to clean my LPs pretty well. I never bought a refill, and I think the Dishwasher was a gift. Mine was made of nice wood with the cleaning pad attached and a hollow to hold the squeeze bottle.

There are diminishing returns in terms of objectively measurable quantities as you move up the price-continuum in audio equipment. "Audiophile" vendors have realized that there's a subset of the population for which the subjective enjoyment experienced is actually determined more by the latter than the former variable... Can't blame them for trying, although their apparent success is quite concerning.

> What would distinguish an ethernet switch "for audiophiles" vs a regular ethernet switch?

two grand

That switch looks like one of these modules [1] that costs around $10 and the IEC power socket is the exact same [2] cheap crap I used on my 3d printers...

[2] https://a.aliexpress.com/_mNpTLDU

The same company sells a standard three prong to two prong adaptor for $45. Package of three for a buck at my hardware store.

Admittedly for $45 you get a sticker on the side and a product that "treats it with 1,000,000 volts of electricity in a process we call Quantum Tunneling for an amazing transformation in sound quality from this modest plug."

https://www.synergisticresearch.com/isolation/accessories/qu...

Does anyone who has looked into this know what's _actually_ going on here? If I made up a scam ethernet switch company, I doubt positive-feedback.com would pick it up and review it positively. How much do I pay for a positive review? How well do all these people know each other? It must be a small in-group of people who all know each other getting rich off this shit.

I (a random Internet person) also consider this theory to be the most likely after many years spent in cyberspace.

Q: Are fuses directional?

A: Yes, fuses are directional. Electricity should flow from the left to the right when you view the fuse. If you do not know the direction of flow you should listen to the fuse inserted in both directions. One direction will sound more detailed. This is the correct way.

https://www.synergisticresearch.com/fuses/blue/

This site is proof of the fact that there is no positive correlation between affluence and intelligence.

Maybe they should sell a fuse direction swapper which turns the fuse around 50/60 times per second so the "electricity flows" in the "correct" direction? Imagine a carbon fibre box around the fuse with that logo on it, containing one of those $0.02 fuses which they sell for $160 and a stark warning not to look inside the box or the magic will disappear. Add $1000 to the price and some audiophile snob will buy it.

If you google "expensive audiophile ethernet cable", you can buy some $3000 to $10,000 cables to go with your new switch.

"This wasn't a subtle improvement and yet I did a fair few Volcano on, Volcano off comparisons before I could really accept what I was hearing. In all honesty despite hearing the positive effects the Vibradome Blue star had made to my other system I was still shocked and surprised this item could make such a difference by just sitting on the amps case. Its not heavy enough to damp it and yet it was making a difference and a positive one; frankly I don't know how."

This is what Russ Hanneman[1] startup would look like targeting people from three comma club

[1] https://silicon-valley.fandom.com/wiki/Russ_Hanneman

At first I thought "...components that might have peaked my interest..." was surely a typo, but then I realized that at these prices you should only be buying if the product brings your interest to a lifetime high.

Though I suppose that would only allow you to buy a single component, as by definition only one could be at the zenith of interest. And then the rest of your life would be a letdown.

The only thing more ridicously expensive would be an NFT of an image of this switch.

Synergistic Research seems to be selling a $30,000 audio cable at https://www.synergisticresearch.com/cables/srx-cables/srx-sc...

I guess even a company like that has to see how far they can go before even their whales scream in disgust.

The only way I can think this could make any difference is if generates less electrical noise from its internal power source or emanates less RFI that could be picked up by the rest of the audio gear.

I'm sure not all audiophiles are dumb and I think a few educated ones pay for expensive cables that are used for digital data. I'm really curious why.

So obviously there is "high quality" and "frivolously expensive" cables, but there is a reason to get a good digital data cable: shielding.

Think of something like UDP traffic. If you have poorly shielded cables, you could corrupt a packet. In the case of UDP traffic, you will never get that packet back. Do this enough, and it may impact sound quality of eg. streaming audio.

Let's assume that the author actually believes that music sounds better with this hardware, and it's not paid-for review.

Would it be ethical to push such person through double-blind test, which (I assume) would disprove that there is a perceivable difference?

The most die-hard believers will insist that if two pieces of equipment sound "obviously" different when you know which one you're listening to, but they're indistinguishable under a double-blind test, then the only explanation is that the testing methodology must be flawed. They simply find the "placebo effect" explanation absurd and refuse to accept it.

I'm feeling almost convinced that this is deliberate satire.

The weights are a real thing. $900 weights... idk.

Shannon be damned! The only way I can surely transmit the highest quality 1 and 0 over a noisy channel isn't through clever encoding and parity checking... its only with high quality copper. Otherwise my 1's and 0's will certainly degrade into 1.1's 0.2's and even negative values!

Screw that 300km of power lines built in the 70s, it is the last half a meter that makes the difference....

There was a story of some audiofools (in Japan if I remember right) who paid a huge chunk of cash to have their own last-mile transformer (not sure of the exact term, but basically whatever converts the last HV stage into normal household voltages) for this exact reason.

I doubt it works well without a golden oxygen free ethernet cable that costs at least $1,500 per meter.

Here you can find a golden one for 3500eur and extra 2400eur cables ;) https://jcat.eu/product/m12-switch-gold/

I _knew_ that there's a use for such a switch if you just get the right cables ^^

Only if your golden oxygen free ethernet cable has also been hand-blessed by tibetan monks, and its jacket made from single source organic free range non-GMO nylon

Of course. But that is so obvious that I saw no reason to mention it.

Connecting your home audio system to a personal utility pole can create even better midranges.

I am so so glad these guys exist: https://www.audiosciencereview.com/forum/index.php

Even that site, though, feeds into audiophile irrationality. The DAC reviews, for example, throw a bunch of measurements at you, but there is no way a human could hear the difference in the best and worst DAC.

> there is no way a human could hear the difference in the best and worst DAC

Are you sure? Remember that a DAC in this context is also an audio circuit, not just an IC performing digital -> analog conversion. I can say with certainty that switching to a USB DAC made a big difference vs using the output on my motherboard, no computer noise + I lost an unnecessary amplification stage. Of course, I would never spend $$$ on a DAC, because as you mention it's a very low-impact component of the system.

The other thing is that DACs which support high sample rates can play your high sample rate music without software resampling, which is obviously not a useful feature for a lot of people but is definitely audible if you do have high sample rate music for whatever reason.

If you think this is interesting, check out the $10,000 "ground block" the same company sells. Supposed to align your audio with the "Schumann Resonance." The mind boggles.

Do I need a different one if I plan to listen to Mendelssohn?

I swear there must be a form of tinnitus which is only present when you are actively listening to something such that people are convinced the sound is some ground feedback loop.

This author is deluding him/herself. Oh well, not my money.

The site is called positive-feedback for a reason. Did you expect it to be a critical review?

Beware of the jitter, that's what the audiophiles say.

But like how much buffer do you need to completely eliminate any effects of jitter?

Probably 2kb buffer

I bet if you figured out a way to offer this with fiber-optic 10GbE to the music server, you could double your margins.

Interestingly the comments on the article are moderated. Needs approval before publicly visible. Some website...

You haters just don't understand how much _fuller_ a `1` bit sounds when it passes through this switch!

Clearly I am in the wrong business. Starting tomorrow, I'm going to set up shop selling high-end audiophile gear. Our first product will be a series of speaker cables, enhanced with cadmium for better alignment of the electromagnetic fields. Price, $700.00 USD / foot. If you have to ask how much the special gold-plated connectors cost, you can't afford them.

It costs like a 2960S with 24 GigE + 4 SFP with lot of more advanced features.

Tell me you don't understand technology without telling me....

This has to be a joke.

A fool and his money.

The spoon farted.
