$10K Ethernet Cable Claims Audio Fidelity, If You're Stupid Enough To Buy It 418
MojoKid writes: There are few markets that are quite as loaded-up with "snake oil" products as the audio/video arena. You may have immediately thought of "Monster" cables as one of the most infamous offenders. But believe it or not, there are some vendors that push the envelope so far that Monster's $100 HDMI cables sound like a bargain by comparison. Take AudioQuest's high-end Ethernet cable, for example. Called "Diamond," AudioQuest is promising the world with this $10,500 Ethernet cable. If you, for some reason, believe that an Ethernet cable is completely irrelevant for audio, guess again. In addition to promises about the purity and smoothness of the silver conductors, and their custom "Noise-Dissipation System," they say," "Another upgrade with Diamond is a complete plug redesign, opting for an ultra-performance RJ45 connector made from silver with tabs that are virtually unbreakable. The plug comes with added strain relief and firmly lock into place ensuring no critical data is lost." Unfortunately, in this case, there's the issue of digital data being, well... digital. But hey, a 1 or a 0 could arrive at its destination so much cleaner, right?

To each his own, I like the tube distortion, but I have ever since I was 12yrs and heard a pair of K-horns in an audio store running off a McIntosh tube amp system.
But I digress. The thing is...those cheap earbuds on an iPod aren't going to sound as nice as my Shure higher end earbuds.....at some point, you do get what you pay for. But one always has to be wary of what's being offered, and do their research, and test things in person.
That all being said, there are some fun DIY things you can do. I found lots of links years back, on taking multiple strands of Cat-6 cable, and braiding it in various fashions into speaker cable. I did my own variant, and I have to say, I liked the way it sounded...in fact, I still have it on my main front speakers (the khorns).
So, if you do enjoy GOOD fidelity in your audio, often you do have to pay a bit, but not always.
Sadly, so many kids today seem to see their music as disposable, and many have never HEARD what a good sound system can sound like...and only know white, cheap earbuds...or worse...the thudding of "Beats" headphones, that so far I've yet to find a tweeter installed.

You bring up some good points in your post. But I have to disagree on one thing. Good quality music reproduction is today more accessible than ever. There was a time when you had to get horn speakers or at least speakers as big as cabinets, class A amplification -solid state or tubes, and a really hard to setup vinyl turntable. Then there was room treatment, speaker placement, and all those shenanigans.
Not saying this is still not relevant. But today, you can get a decent pair of headphones (sennheiser, audio technical, akg, grado, fostex/MrSpeakers, etc), a decent DAC and amp (Schiit, Audio GD, etc), and good quality source and good quality digital (hi res or even redbook) - all at even a college dorm budget, and similarly compact.
I remember the days of the walkman and audio cassettes, and for sure, the progress has been dramatic. The only irony being that the single most important piece - the quality of mastering and quality of recording - has largely gone for a toss. Today, it is all about loudness wars and auto tune. But that is a different matter.
When people pursuing any hobby go beyond a certain expense level, they make purchasing decisions for most things other than money. Why is there no Slashdot argument about people paying $3 million for a vintage Ferrari or a Jag? Is there any basis to that price! Is the buyer, no matter how much an auto enthusiast, ever going to take his or her vintage Jag for a really rough spin that could risk damaging the car?
Maybe the analogy is not accurate. Fair enough. But a lot of audiophiles with really high end systems do find a difference in sound even with trivial component swaps. They will even claim that placement of certain objects in the room alters the sound.
But before dismissing them as twats, it might be worth thinking about how idiosyncratic and bizarre other people are who are equally immersed in their hobby or pursuit. The guy who is cooling his Intel CPU in liquid nitro to get the last bit of over clock - really, what practical purpose did he serve? And he probably spent a bunch of money on his rig too.
The strangest thing of all is that music is one of those strange beasts that changes quality with every trivial change in component, room, source, you name it. That is what gets audiophiles hooked. Maybe and probably it is psychoacoustics. But if you can hear the difference, it is there, right?
Now how much tweaking and money you want to throw at this pursuit, that is a very subjective thing. But dissing it and ridiculing it is also wrong. It is only one of the many things that continue to fascinate us as a species. And music is indeed very very special to most of us. We just don't pay enough attention to this sense.

You know just enough to be dangerous. You're also wrong. Each pair in a Cat 6 cable has a different rate of twist. That's done to reduce crosstalk between the pairs. I often use short (<10 M) Cat 5 patch cables for temporary 1G connections without issue, Cat 6 becomes more important when you're bundling cables together and using longer lengths (100 M max). Regardless, any errors which occur can be recognized and recorded, so any difference between cables could be easily and objectively quantified - no need for subjective "the soundstage immediately opened up" BS.
The length of different pairs due to the difference in twists is insignificantly different.
You then go on to confuse matters by comparing 1G Ethernet to HDMI to I2S, three completely different things, with different signalling at different rates. 1G Ethernet runs at a clock rate of 125 MHz, encoding 8 bits per baud. HDMI 1.3 has a maximum clock rate of 340 MHz, making transmission line length more critical.
I2S [archive.org] does NOT have 3 clocks as you claim. It has a single clock, a word select signal (used to indicate whether left or right channel info is currently being sent, sometimes called the "word clock," even though it changes synchronously with the bit clock), and a data signal. Used for standard CD audio, it has a clock rate of less than 1.5 MHz. Even with newer "high definition" audio formats, the clock rate is still significantly less than either 1G Ethernet or HDMI. It tops out around 12 MHz for 32 bit stereo at 192 KHz. For more channels, additional data lines are added. But, transmission line length is not as critical as for either Ethernet or HDMI, which run at 10x+ the speed of I2S. 1/2 cycle of a 12 MHz clock is almost 50 feet long on a wire. A length difference of fractions of an inch simply doesn't matter.

CD transports do not have this problem. CD read jitter only happens if you're trying to read audio CDs at the block level, something they weren't really designed to do. A regular CD player will not do this.
The second type is transport clock jitter. The digital interface between CD transports and DACs doesn't have a separate clock. It's derived from the data itself. That process wasn't always perfect. In the mid 90's, the recovered clock was sloppy enough that bad ones were audible. Stereophile did a useful article measuring cd transport jitter [stereophile.com] during that era.
Nowadays the clocks and clock recovery circuits are so much better, I'm skeptical this is a real issue anymore. And most computer audio players buffer their data and then generate their own clock, which completely eliminates transport jitter.

Yeah I never understood that, why try and recover the clock signal from the data stream? If I where designing it I would have my DAC monitor the stream to calculate what the clock signal is supposed to be then generate my own dam clock signal. Let's face it there is only a handful of possible clock signals.
For that audiophile approach I would then today use a chip scale caesium atomic clock for two orders of magnitude better accuracy than an oven controlled crystal oscillator to generate my internal clock s

I spoke to a friend who is in ultra-high-end business about those cd transports and how can one sound better than the other (he's not stupid) and after a while we came to the conclusion (well I did anyway, he knew this) that it all boils down to jitter and real-time error correction.
Much of the time, the perceived improvements in high end audio electronics (not including speakers and other acoustic devices) boil down to volume differences, and the imagination of the listener, which is fueled by clever marketing and obsessive-compulsive worrying about imperfect audio.
Even nowdays if you wish to rip a cd that's as clean as possible you have to do multipass read with that german free software I forgot what it's called now.
Actually, if there are no problems with the disk or the drive, one can often just copy the audio tracks at full speed with no software error correction, and the result will be binary identical to that of the slow multipass read. The latter is at least still somewhat useful to confirm the lack of errors, although that could also be done with an online database of checksums. The last CD-ROM drive I had that definitely needed jitter correction was bought in the late 1990's.
I believe silver wire ethernet cable will be better and super quality rj45 will contribute in some miniscule way to fewer error corrections on layer 1, bit $10k worth? Don't think so.
If the cheap network cable cannot be used to transmit audio reliably, then it would also have issues with other types of data. The playback is also buffered (which it needs to be in any case, even in a hardware player, as the data is sent in packets), and as long as the buffer does not underrun, there should be no issues with the audio quality even if the occasional packet needs to be sent again because of errors. When the buffer does underrun, it causes skips, stutters, pops, and other obvious distortions in the audio, rather than subtle changes in the tonal balance, sound stage, or whatever. There could be dropped packets if the protocol used does not support re-sending them, but that produces similar audible effects to those of buffer underruns.

You can do one of 2 things.
1. You can have a precision spin mechanism that ensures a constant transfer rate.
2. You can have a flimst plastic spin mechanism and a nice big data buffer.
Guess which one you're more likely to find in a cheap CD player.
A precise spin might help if you want to minimize buffering delays, but it's questionable.
CDs aren't precision-balanced, so there's only so far that you can go on the spin mechanism without using a relatively massive flywheel. Which will have a spin-up delay.
Once the buffer is loaded, the unloading process is controlled by a megahertz timing source, and I defy any audiophile to hear jitter in that.

Sorry, but you're wrong. Audio CD's use reed-solomon ECC, and it's the reason why a little speck of dust or small scratch doesn't affect the audio.

There is no error correction on audio CD.
Yes there is. It uses a dual interleave Reed-Solomon code together with 8-14 modulation and three joining bits.
192 data bits are encoded in 588 bits on the CD.
Those 588 bits comprise:
24 bits sync word plus 3 merge bits. (27 bits)
33 EFM words of data of 14 bits plus 3 merge bits per word (561 bits)
The 33 bytes of data are:
24 bytes of audio (12x16 bit samples)
8 bytes of parity.
1 byte (8 bits) of subcode information.
The merge bits allow the min/max separation of 1s to be maintained between EFM codewords and also allow the data to be DC free

Jitter isn't caused by cables. Its caused by the devices either side.
Typically on switches or routers, where packets are received on two different interfaces, and need to be transmitted out a third. If two packets are received at the same time on the two ports, one of them must be queued while the other is being sent. This will introduce a small amount of jitter. This is magnified with a busier network, and is one of the things QoS tries to eliminate for certain traffic types (typically voice on enterprise/

Your switching gear should be able to pick up on Ethernet re-transmits. Even the oldest managed switches can do that.
If you have a network which has more errors on the cable than those that occur when you physically pull the cable out, then you need to re-wire.

(bought a job lot of those cables years ago for a quid a pop, they were marked at £45 each(!), there is NO difference between those and standard Tandy dangle-off-hooks cables.
