content: To be fair have you listened or tried but I suspect because of your biases, no. In acoustics there is such termcalled psycho acoutics this is not wishful thinking but the way the brain and ear interacts. There are papers on the subject. It is a fact that everything or object/element in this universe has a natural resonance even the planet earth has one it's called the Shumann resonance of late it is about 7 hertz. to pooh pooh anythingas audiophool is being closed or narrow minded. There are some things that cannot be scientifically explained currently although there is snake oil out there.Let's take a real world example, compare the sound of a wood violin with an electronic one made of metal and acrylic or a wood piano with an electronic one/synthesiser. It should be obvious. Why do violin playerssought after hundreds of years old violin made by Stradivari or Guarnari? There are serious papers on this too. Even all the modern scientific instruments for analysis of these violin's acoustic properties NO one to date has manage to replicate the sound of the famous ancient luthiers (musical instrument craftsman). Is it just due to aging like fine wine or something esle? There is even speculation that the trees from a certain mountainous region in Italy that are transported down and then subsequently floated down in the sea ways to the place of trading due to this salt water emersion certainchemical reaction took place and there are gold elements embedded in the wood fibres which could account for the specially sound quality and also the secret way the wood is being dried. All this even makes for the tendency to dismiss discoveries as make believe but you are entitled to your opinions.PS: If you have the chance go visit the german Steinway piano company you will be surprised as to their ways of choosing the wood for their pianos.If music be the food of life play on.

Psychoacoustics is what makes lossy audio compression possible, as well as the equal perception of tones at different sound pressure levels for reproduced sound (why your stereo has a "loudness" control)It has absolutely nothing to do with snake oil bullshit like cable elevators, magic pebbles, etc

content: At nearly sixty my hearing is OK but nothing spectacular, but I did at one point meet someone who had AMAZING hearing. She was a violinist in the Budapest Radio Orchestra and she was able to tell the difference between a Stradivarius and a modern instrument by ear, every time. Could I hear it? Hell no, and that's after listening to classical music all my life.A quick example of how good her hearing was. One evening we were listening to a CD of Beethoven's 5th and suddenly she got up, paused the CD, and then shifted it back ten seconds or so. Can you hear the sneeze she asked? I'd been listening to that CD since 1985, it was one of the first CDs that I bought, and I had never heard that orchestra member sneeze, but she did.I can guarantee that she would not hear the difference between a cable on the floor and a cable elevated 3cm above it. The varnish and the wood used to make a Stradivarius are things that make a measurable difference on an audio spectrum analyzer and some (but not all) can hear the difference, even in a double blind test. Elevating a cable above the floor to improve the sound makes no electrical difference to the signal and thus is an audiophool product.One final thing, I wired up her stereo system using 6mm shower cable to connect the speakers and she thought that it was wonderful, even though the cables were on the floor.

content: There are some plausible physics for this to make a difference in some situations. For example a ferro-magnetic floor, poorly attached to the sub-floor so that it rattled under foot traffic. The varying inductance as the cable bounced on the floor could result in intermodulation and other tones that could be heard by some golden ears.Of course most of the rest of us would be hearing the rattle of the floor directly, and would fix that first if we had to listen to our music there. Which would then make these devices worthless. Same kind of logic applies to other plausible physics explanations. Puts these cable elevators in the audiophool class for me.

content: Rather expensive for a block of foam with a V cut out of it.The only slight benefit this could possibly have, is to prevent vibration transfer between the floor and speaker cabinet via the cable. But then who cares if the floor rattles a bit, the whole point of speakers is to rattle floorboards.Given the average Audiophool has 100% OFC copper, 1million strand count, ultraflexable cables, I fail to see how much vibration could be transferred anyway.Lets be honest, this is a product for idiots that don't want their overpriced cable getting dirt and dust on it.

I have a pair of Audioquest speaker wires and some fancy RCA cables, but I bought bottom of the line and I wanted them mainly for the looks. I never did hear any actual improvement in the sound nor did I expect to.I first saw "elevators" for wires being sold back in the 90s and I knew even then that they were pretty useless. The ones I remember were made of wood and not terribly expensive though. Of course 10 for $150 isn't all that ridiculous considering there are cables that run thousands of $$$ per meter.

Now what is the wavelength of 20 HZ hehe.As for the violinist, she is a performer, and am sure she doesn't like coughing sneezing and hacking during the quiet parts of her solo. So is 'tuned' to it.Unless I was using the best of tape recorders , I always could hear (or imagine to hear) flutter in piano or similar pieces. The invention of CDs was a boon to me.Unless I use the finest of CD players, I can always hear jitter(just kidding)

content: Quote from: singapol on July 24, 2016, 09:46:22 amJesus wept. I don't know where to start. I think I'll leave the whole post in quote so people can re-read it. Violin players, and many instrument players generally go for famous names because they are famous and expensive. This also means others have looked after the instruments, so they are likely to be in good order. As for sound..:http://www.thestrad.com/cpt-latests/blind-tested-soloists-unable-to-tell-stradivarius-violins-from-modern-instruments/Also, a misunderstanding of 'psycho acoustics', mixed in with words like 'resonance' doesn't help trying to convince others that raising a cable off the floor improves its electrical qualities. Psycho-acoustics is very well understood (although no dobut, there is more to discover). I'm sure you have listened to MP3's, or watched a DVD, or used a telephone - all of which use really quite complicated processing to abuse how our brains process sound in order to reduce bandwidth for high storage density and lower transmission bandwidth.'Shumann resonance' is a generally seen as a red flag by many engineers. Yes everything has resonance, insofar as a cavity, to physical dimensions. But how does this relate to psycho acoustics? Perhaps the brain automatically equalises sound to flatten out any natural resonance of the ear, but its generally all non-linear anyway.And then you bring wine into this. Wine. I suppose your point is, we all have our opinions, and experience things differently, we see, hear, and taste differently and there is no real way to know exactly what others sense. But other than that, god knows what you're on about.Gold in wood makes it 'sound' better? Why would gold make it better? why not chocolate, or rat droppings? Is it because gold is seen as valuable, and therefore must make everything 'better' in some grossly subjective way? I have in fact played on a steinway (was given 10 minutes on it!) and it sounded beautiful. As I would expect seeing as it costs so much. But I suspect they are choosy about the wood they use because nature doesn't have quality control to the specifications of piano makers, and their customers expect them to have some strict materials selection if they are going to charge as much as they do.I really shouldn't have seen this thread as it just makes me look like a ranty mcrantface :/Edit: I fell for it didn't I? it was a troll post.Thank god I'm not a fish, I would not survive long.

content: Because if you just use plain ordinary items to lift the cables off the floor, they will still be subject to induced oscillations at audio frequencies. Only the special $150 each support towers have the proper acoustical insulation properties to clean up the sound signals in your speaker wires. Of course if you don't use the pure copper oxygen free unidirectional speaker cables, you're just wasting your money on the cable towers.

content: If there's anything good about the decline in the audio business it is that there is less money going to hucksters. But they will always take there cut as there IS a sucker born every second.Perhaps as the younger generation that have grown up listening to low bit rate mp3's etc and quite happy doing so the hucksters will have to find a new market for there talents. If you can't tell the difference between low/moderate bit rate lossy compressed music then you probably won't be in the market for a better audio system and maybe that is where this story ends...Brian

They might spread their word, and at the end of the day one of the ones working in a serious audiophile's directional cable, being forced going the wrong way half of the time, will get irritated and mess up the music experience. Bloody amps not keeping up with technology and still creating AC at their outputs.

This reactive energy is several orders of magnitude higher that any signals it may pick up from "other sources" and is actually one of the main challenges for amplifier designers.

content: Not sure if I've seen unidirectional speaker cables - now there's an idea - not only unidirectional speaker cables, but different materials for the two conductors. One for enhancing the flow of electrons, the other for enhancing the flow of positive charges, so you definitely have to hook them up the right way round. Throw in some physics terminology, maybe mention that research done at the LHC has proven this effect, boom, instant sales of $25k per meter speaker cables.However - there definitely is a unidirectional audiophool ETHERNET cable. Might have been included in this thread even. Insanely expensive, of course, and it has directional arrows on it. I reject it outright as I demand that my ACK packets have the same high quality as my data packets!

content: Quote from: rdl on September 16, 2016, 01:27:12 amTrue directional cables have multiple layers of shielding. The inner layer is connected at both ends and the outer layer connected to whatever end is less sensitive to noise, usually the source. The main exceptions are sources that do not have a direct connection to ground such as microphones and guitars.

content: While I do agree that there is a lot of ridiculous stuff sold in the audiophile world, not everything is totally stupid.I have had the priviledge to spend some time on listening sessions with audiophile equipment in propper rooms.I too came with the preconceived idea that 10.000 Euro speakers are bullshit, as well as 5.000 Euro valve amplifiers.To make it short: for the first time I HEARD how bad an ipod sounds, when connected to a propper audio equipment. I had brought it along with "my" songs and after one or two I resorted to CD's...Same goes for mp3 with up to and including 128 kbps. It sounds lousy against a CD. And yes, I can hear that.At 160 kbps upwards I cannot distinguish the source (CD or mp3), except on special occasions when I am hinted to pay attention to given details. Different people do have different perceptions and you can train your ear. So I am not defending the impossible - i.e. mp3 at 320kbps will be undestinguishable for most people, except people with exceptional hearing and propper training. Many audiophile would disagree, but I think that would be bullshitting.But the really overwhealming difference for me was to experience familiar songs in a way, where I could hear details I never noticed before. Also, with a propper setup you can locate each instrument in space. All of this gives you an experience as if you were entering the stage where the music is being done. Great listening experience!After some time I got used to this sound quality and I started for instance to notice how aweful the sound is at many live concerts!Now to the "audiophool":Because I am neither rich nor an audiophile willing to sell his car in exchange of an amplifier and speakers, I got my own stereo out of eBay components. Vintage audio from the 70ies and early 80ies is pretty cheap, but probably produces the best sound per buck.The best of my systems has cost me about 250 Euro and uses a PC to reproduce music (over an Audio Fidelity DAC). The sound is pretty good and beats any modern system based on iPod stuff hands down.So what do you get if you pay 15.000 Euro instead of the 250 Euro I spent?First off, you get something new and don't have to repair, clean or exchange cracking potis...Then you get a much better sound. Imagine having a FullHD 42" LCD and then you move over to an 84" 4K screen playing native 4k material. That is the difference. Is it worth the price tag? That has to be decided by yourself.And if you spend 15.000 Euro or more (I have listened to one setup with a 100.000 Euro price tag), you need a propper room to benefit from the sound. And then you need matching furniture: a comfortable couch, etc. And after spending this fortune, would you the buy cheap speaker cable?Also, audiphile equipment in this price range is to be considered art - it doesn't only sound great, it looks great, too. It has the signature of the brand and engineer who developed it. Hence why there is a market for speaker support, cable support, etc. You wouldn't put a cheap frame on an authentic Renoir, would you?Much is indeed nonsense, but not everything. I recommend that you seek an audiophile store and ask for a listening session. Serious stores will be happy to let you sit and listen for an hour or so, helping you through your preferred bands. Listen to the sound and enjoy. Relax and never mind if some components (monster cable) are silly: at a given price, nothing matters.And after spending one hour listening to Pink Floyd's Dark Side of the Moon, try to listen to this same album on a modern 200 Euro system.Audiophile stores are happy to let you listen to their setups because they rely on making people familiar again to great sound - I was never refused by any store. And they won't be agressiviley trying to sell you anything.Regards,Vitor

content: Quote from: Bicurico on September 16, 2016, 09:25:28 pmIt's content dependent. Most music does indeed seem to do well at 192kbps, but the compression artifacts are audible in a few songs with complex content. Storage is cheap enough nowadays that there's little reason to use anything less than 320kbps or (if supported) FLAC.I have actually seen a 85" 4K display at work. As a desktop display, it would be way too pixellated. But it works great for giving presentations. A 85" 5K display (if it existed) would be better. Or indeed, an 8K, but that's many years away.

content: The best, and in fact what should be theonlyway to decide whether a component, technology or signal encoding makes a difference in the sound is to run a properly moderated ABX test using the two things in question. Granted, it's not easy to set one up for things like power amplifiers, but low level components, passive items, and source signals can be tested pretty easily. It's amazing (or maybe just satisfying) to see alleged differences evaporate when they are properly compared with a methodology that takes the visual evidence away from the audiophool. I've done this with lossy audio sources and even preamps, and it's evident that the human ear is terrible at distinguishing some things, somewhat better at others.https://hometheaterreview.com/why-do-audiophiles-fear-abx-testing/I haven't read the comments, but I fear they would destroy my faith in humanity all over again.
