Anything "audiophile" in the digital domain is all equally absurd. The only difference is that some require a half-second of consideration and others require literally no thought at all to identify as stupid.

You mean like those people, who argue, that: "Everything is a sequence of Zeroes and Ones, therefore the signal either gets transmitted or not !", while totally leaving out the fact, that this digital signal material izes in the real world via an analogous signal, which is electricity, and therefore each digital data transmission (as long as not optical) is submitted to physics that happen totally outside of the "dig…

I don't understand the point you're trying to make. Everything is ultimately subject to physics, including optical signals. Nobody claims otherwise.

But it is incorrect to say that digital transmissions must be at the mercy of physics. Digital transmissions can defy physics. There are numerous techniques which ensure that a signal reaches the destination with precisely zero flipped bits and exact timing. And even when the signal has no integrity mechanisms, in practice the error rate will be low enough to never matter in practice.

And you know what, even if bits were getting flipped and jitter was extreme, you still wouldn't have signal degradation in the ways described by audiophiles; you would get a raised noise floor. Random error is noise. Noise is random error.

Of course this is never an issue. We can send digital signals that are millions of times more complex than digital audio, with zero problems, using equipment that is insanely cheap. The assertion that the extremely low data rate PCM audio signals have some special risk associated with them is delusional.

What I like about this article is that they just find a few weirdos in Japan who actually end up doing that, and you get a blanket statement like "Audiophiles in Japan" while the proper headline should be "A few crazy old rich people". Journalism at its best.

That depends on what categorizes "Audiophiles". If out of a million self-proclaimed audiophiles, a few hundreds are genuine ones and if out of those, a few tens are behaving this way, I think it can be reasonable to say that the audiophiles are behaving like that ;) You must be aware that the audiophile community lives in a completely different world, where recreating sound is of more importance to them than rather enjoying the music on its own. The amount of money and time these people put in satisfying their "passion" is unrealistic. So, no. The article is right in talking about the weirdest of the weirdos ;)

I fully agree that an external USB DAC can have a much better output quality than the motherboard output that can be influenced by interference; I have an external DAC myself, but I bought it for about $50 (list price was $200 in a hi-fi store, I ordered it from a small reseller). Not talking about the $400 box with $5 parts in it, but about common sense (plus some physics and math) in understanding what a DAC does a…

I do agree. I think it has to do with the fact that most motherboards have pretty terrible analog audio support. Every motherboard I've ever had has sounded meh compared to a cheap USB DAC. It would be super interesting to compare an iPhone analog vs iPhone with a DAC. I guess you'd have to use an old iPhone with an audio jack though :(

Even the motherboards have gotten better over time. I recall being over at a friend's house in the early 2000's and he was saying, "my speakers are so bad, I guess I need new ones" and I said, "wait, try plugging those into a different source", which we had in the form of another friend's laptop. The audio immediately went from tin can quality to reasonably transparent. The issue was with the cheap DAC in his computer.

But I usually go with onboard sound these days. I did get a FiiO E10K when I got new headphones recently, but I've put it away even though the sound is noticably smoother and less compressed-sounding than my onboard sound - it's another cable and associated hassle.

The reason to go for pricier stuff in my mind is to get more I/O. Good audio interfaces for recording can run you hundreds, and you're paying there mostly for having more channels and some recording features. There's more of an expectation of getting what you paid for.

I work in the audio industry, and I can say two things: 1) most everything they do is audio mysticism (i.e. complete BS), and 2) they are very profitable customers.

As a trained EE, non-practicing, I would think it would be far easier to install filters/conditioners on the line to normalize the voltage and current (e.g. performing phase correction). Also, if you had a local AC->DC->AC conversion, could probably get a more uniform power source frequency. Not sure, been a long time since ive studied this, but I think a lot of thw high-end audiophile stuff is snake oil. I've been a…

I used to work as a musician professionally, and have dealt with “dirty” power in old theatres. It was solved completely by bringing in a power conditioner. I don’t know why they can’t do that in this situation.

Now to sell them a motor-generator set.[1] Total isolation from power fluctuations. The only connection between input and output is a rotating shaft.

I once worked in a mainframe computer installation which had one of those. Before switching power supplies, many mainframes used them for power cleanup. Cray used them to convert to 400Hz, so the power supplies had smaller transformers.

Tubes, cables now this. It seems more like religion or superstition than technology IMHO. If you want to take it to the limit, hire someone to come into your home and perform live for you, then you can eliminate all the sources of distortion. Not only would you be hearing the ultimate perfect sound, you would be providing employment for artists. Seems like a win - win to me :)

Tubes, cables now this. It seems more like religion or superstition than technology IMHO. My advice to everyone is to never ask a hard-core gamer what he's tweaking when he's got his favorite rig open, and cards scattered all over the workbench. There's enough technological superstition in some of them to summon the devil.

Why, and how, would one "tweak" a machine?

The 82-year-old lawyer already had a $60,000 American-made amplifier, 1960s German loudspeakers that once belonged to a theater, Japanese audio cables threaded with gold and silver, and other pricey equipment. Meanwhile, my wife plays her Dean Martin records through her own personal 15-watt AM radio station in the closet, picked up on vintage tube radios scattered around the house so the music sounds like it was inte…

Would love to hear about the hardware she's using for this! It's very cool.

One of the things I truly will never understand about "Audiophiles" is their willingness to spend money on products that are, from a technical basis, indisputably categorized as snake oil. For instance: https://www.amazon.com/AudioQuest-Diamond-feet-Braided-Cable... It's an HDMI cable! The video signal has CRC in it and is packetized, it's either going to make it or it isn't. The quality of video delivered at, for in…

HDMI cables used to be a great example, but now there are something like 8 different levels of certification and only the highest have the bandwidth to carry a 2160p, 60fps, 10 bit, 4:4:4 signal. And as far as I can tell, they are all passive so your source or sink can't warn you that your cable isn't compatible. You'll just get artifacts. The AmazonBasics cable will do 18Gbps, so it can do 2160p, 60fps, 10 bit, but…

Okay, so the last time I bought hdmi cables I got 2.0 rated. Just looked and HDMI 2.1 rated 48Gbps cables are $25-35 each for 6 foot. That's not totally unreasonable. Now how is a $350 cable or a $800 cable any better?

Yes, you can absolutely sell "HD SATA" cables. To paraphrase, "There's a new audiophile born every minute". https://jcat.eu/audiophile-sata-cable/

I once saw a shop that sold gold plated fiber optic cables...

Many years ago I saw gold plated TOSLINK cables. They were $500. TOSLINK is a pure fiber audio connection standard that uses multimode fat plastic fiber.

This must be satire, right?

There is no stupidity limit. Research flat Earth!

I'm not sure what's worse.

From my limited observation of flat-earthers on YouTube, they at least seem to be willing to do measurements but then either misinterpret the results (due to lack of knowledge) or knowingly twist them to say what they want to say.

Audiophiles on the other hand seem to reject the whole idea of taking measurements.
