content: I like how those idiot jump on to any BS. New audiophile toilet plunger - mill spec handle stiffness. What is the price point?I'm guessing it is not not a huge market, but it is super easy to come up with product ideas, since they buy anything you throw at them and ask for more.It is just amazing how those people fail to grasp how anything works at all. They seriously think that the quality of the crystal on the SSD matters at all. In reality their shitty flac digitized from vinyl will be instantly cached and SSD will go to sleep, but it will be sleeping on such an accurate clock.And they are "burning in" the capacitors. LOL.A question that sums up pretty much the whole movement:QuoteAnd a response:QuoteLOL.A critical component that they all are missing is the screw that holds the SSD. The entire sound quality is all digital and compromised if that screw does not cost at least $100. Luckily I have such screws in stock and the results are amazing. And once the screw burns in for another 100 years, it will have the ultimate sound quality.

content: It's only $800 for 333 Gb (https://www.zzyzxphile.com/eng/products/revelation_audio_ssd/), that's really cheap for an audiophoool product. They must be using low quality components there. I'm guessing the future $4000 model will sound better.(also I love from the forum one mentioning that he can hear a difference when he runs the operating system from RAM instead of the SSD)

content: Quote from: Daixiwen on December 08, 2021, 07:38:43 amIt is a homeopathic action. Just presence of the device in the system improves the quality of sound. Don't even need to plug it in, just keep it close to the PC.I also like how they ban everyone who dares to question the science of the whole thing. They obviously know that they are fools, but they can't admit it now, so they have to keep on pretending to hear stuff.

content: I never understood those discussions on the ”sound” of audio data from different hard drives and SSDs. If the drive is good then data is data. Audio files written to and from them will be identical from all of them regardless of model and brand.If there was any difference between the data on different drive brands and models then applications (ProTools for example) would be corrupted on some drives and not others. Applications don’t tolerate data corruption. If you copy an application between drives and it runs then the data is identical on all of them.Unless there is some deep technical voodoo that I am missing?

content: In every single sales point, this is utter nonsense.If the data read from the SSD is altered by the voltage supply of your motherboard, your whole system would be in serious trouble, I doubt it would boot up at all. Buffer caps of this size are not needed at all on regular systems.High precision clocking is another complete BS technical detail of this SSD - the data gets RAM-cached on the SSD (tiny internal controller RAM buffer oder larger external RAM buffer), transferred into computer RAM, processed by CPU, piped out via PCIe to a DAC, passing at least two more, probably three, RAM buffers. So your output signal gets passed around buses and caches several times - a precision clocked SSD controller has no influence whatsoever on your output.The only failurepoint of a SSD however has been completely ignored. Talking about "controller heat throtteling" here. Which *is* an actual issue, alas not as much on audio streaming data transfer rates though.

content: Quote from: Haenk on December 08, 2021, 10:55:48 amVery much this. The only possible way to convey digital audio is by copying it, into and out of buffers. (I hope RIAA and the media industry mobsters are reading this and fuming from it!) This is, by the nature of sampled audio, something that is a stop-and-go procedure. Like paper mail. (and then we have not even started discussing what happens to bitrate-reduced audio, like FLAC or Ogg Vorbis; I'm just talking about what happens in a system where 48000 24-bit samples per channel are conveyed per second. ) Therefore, once things early in the process are just-in-time enough to keep the last buffer full (which in disk playback is trivial) theonlyclock that is important, is the sample playback clock in the D/A step. Everything before that can be on paper tape, read out loud by a gnome, for all I care. As long it is coming fast enough to be buffered before being paced out by the sample clock.But the gnome must be wearing red socks. Or else.

content: Quote from: ataradov on December 07, 2021, 10:15:41 pmYou should market a line of audiophile screws and see if anyone buys them. How hard could it be to get some decent quality screws gold plated? The rest is all in the packaging and marketing. People with more money than sense will buy this stuff, who am I to complain about it? People also give their money to extremely wealthy megachurch pastors, the old saying that "a fool and his money are soon parted" has always and I suspect will always be true.

content: Quote from: Synthtech on December 08, 2021, 10:01:54 amThe placebo effect is a real phenomenon, if a person believes something will improve the sound then it will sound better to them.Somewhere I read on a blog or something someone was comparing a bunch of capacitors used as the bulk filter before a 3 terminal regulator powering a preamp and claiming he could detect differences in the sonic qualities between different capacitor brands. Total nonsense of course but he believed there were differences so it sounded different to him.

content: Quote from: james_s on December 08, 2021, 08:31:34 pmThis by itself is not surprising and mostly fine.What is more interesting to me is not only reluctance, but outright hostility to any sort of scientific measurement. Would not you want to characterize the improvement in quality? There won't be any difference, of course, but those people already know that. So what gives?

content: They are hostile for two reasons: of course, first because they know that'll make it apparent that there is no measurable difference, but second is that people confronting them on this are themselves hostile. I admit there are good reasons for that: those people want to show those products are essentially a fraud. But when you're being hostile to someone, you can't be surprised they'll react by being hostile themselves.It's just a market. Anyone willing to shake this market will get hostility. It's not even specific to "audiophile" gear.

content: Quote from: james_s on December 08, 2021, 08:28:02 pmPick a "novel" material, that does have different properties from steel/stainless. Market the crap out of those differences and any tenuous link to something audio, pick any of their doublespeak/codewords and suggest links from that to the actual science/engineering. Then offer a gold plated option for extra!This is no different to nutraceutical marketing, carefully skirting around strict advertising laws of actual medicines. But that market is huge and worth exploiting.

content: Quote from: james_s on December 09, 2021, 12:27:00 amSure, but I was talking about the buyer's side. You get the thing and it feels like the "base got wider". Would not it be nice to know just how much wider it got? It feels like it would be a natural desire to differentiate when you are getting a really good deal and when you are being fooled. Those people seem to just accept any random stuff, like scamming does not exist in that world.Audiophoolery seems to be the only hobby that does not operate with numbers. Other hobbies go the other way around - "I just got my new graphics card and I get 5 more FPS in Minecraft". Often improvement is marginal and may not be objectively worth the price of the upgrade, but there are still numbers involved. Nobody compares how things "feel", often people would even acknowledge that it feels exactly the same, but hey, the number is bigger, so it has to be better. There is at least some objective involved.With Audiophoolery the objective seems to be to pay as much as possible for things that do nothing. I guess it is something.

content: Quote from: ataradov on December 09, 2021, 12:40:50 amI look at it like art, what does a painting do? What does a sculpture do? What use is a diamond necklace? You can even buy prints that are indistinguishable from the original to all but the expert eye, or synthetic diamonds that are technically superior to the natural ones but that doesn't stop people from spending obscene amounts of money on originals. People want that stuff because it's expensive. I don't understand the appeal of expensive art or jewelry and I don't understand the appeal of absurdly expensive audiophool gear either but if I had to choose one or the other I'd pick the audio gear, at least I can use it to listen to music and that's something, even if I could buy something that sounds just as good for a fraction the price.

content: Not really. Serious art or jewelry is bought because somebody likes it or because it's an investment, i.e. it will hold its price.Few audiophools treat gear purely as an investment (particularly flash memory) and exactly none of them can admit that the thing they like in their gear is the looks and the delusion it causes rather than the sound.They are akin to "investing" all your money in fake diamonds.Which is why every technology forum has a corner devoted to mocking audiophools, but no one is seriously triggered by art collectors.

content: Quote from: magic on December 09, 2021, 07:48:11 amI disagree. Looks is a very large part of it, otherwise there wouldn't be so much attention paid to making high end audio look good. And what is wrong with that? It's art that serves a useful purpose, it is almost entirely about how it looks. A lot of the gear is a good investment too, look at what classic amplifiers, speakers and turntables sell for today.
