It is a mystery why you periodically feel compelled to spout nonsense about Internet like some kind of Belgian town square carillon. We all know you are more than capable of manifesting intelligence, and in fact many of your posts are a delight to read. Yet here you are again braying to the moon about UDP, which is not, never was, and never will be used in audio streaming, and therefore is utterly irrelevant. However, if you're streaming the World Cup? Yes UDP. But audio? No.

You are welcome to ask your questions about ethernet cables making a sound quality difference on a computer networking forum. Network Engineers, such as my Son are trained professionals. If the textbooks were wrong, the internet as we know it would not work with any degree of reliability. In addition, entire textbooks and decades of research would have to be revisited. Ethernet Cables Explained | Eaton Please read the above in full. The improvements you hear are simply less noise, or no high frequency noise riding along the power lines of the ethernet cable. This kind of noise can manifest in a system as "less polished, smoother, more rounded" as sonic presentation qualifiers. Aside from that, they cannot improve the quality of the DAC beyond what it is already capable of. An external master clock (temperature controlled crystal oscillator operating at 10 MHZ may outperform one that is clocked at a higher frequency (in MHZ); simply because it is more stable and oscillates more precisely. The DAC chip(s) and even OP amps need to rely on stable clocks and precise voltage references to operate at the highest level. The master clock in your DAC or CD player is doing the heavy lifting. Adding an external clock or word clock may help with increasing sound density and information retrieval from your music, as it impacts the time domain directly. Better time domain accuracy = more accurate presentation. And if you get voltage and current correct between all components, then you unlock a very close representation of what actually went through the recording console and microphones. An ethernet cable by contrast cannot physically improve any of these things. It was never designed for such a task in the first place. |
Honestly, I’m no engineer — far from it. So all of this highly technical talk about Ethernet cables is pretty much above my pay grade. However, it makes some amount of logical sense that a well-made Ethernet cable will sound somewhat better than a cheaply made one. The real issue to me is the degree of improvement versus the cost. Does a $5000 Shunyata Ethernet cable sound better than a $100 one? I sure hope so. But how much better? Is a marginally audible difference worth the price? I am a big Shunyata fan and have a full loom. The power cables were a noticeable improvement over stock power cords, and the speaker cables were a noticeable improvement even as I went up the Shunyata line from Alpha v1 to Sigma V1. So at least as to power cables and speaker cables, the difference in my system was easily discernable. But I speculate that the amount of audible improvement becomes less and less with digital cables like Ethernet or USB cables. For those who want to blow $$ on the “best,” hey, it’s your money. Is it worth it? That is a very personal decision. What is puzzling to me in the whole “cables don’t matter” argument is that logically, I would think that if there is a sonic difference, that sonic difference should be capable of measuring, with REW or something. If the soundstage is deeper or the background “blacker,” shouldn’t that be acoustically measurable? Those are the types of differences that might not be answerable by frequency response or oscilloscope, but I would think could be measured. I know that my first foray into power cables — a switch from a stock cable on a Plinius SA100 Mk. III to an Audience Power Chord, resulted in an immediately noticeable improvement in bass response. What can’t that be measured (or can it be?) |
@frank009 thanks for your thoughtful reply. I would agree with most of your statements, except for the part about USB not being an "audiophile" cable. Not sure why that makes any sense. You'd think companies that design cables specifically for audio would make the best solutions for this particular application. Also I am curious what your system comprises and have you ever tried different cabling in the digital realm to see if you can ascertain the difference? It is highly system and user dependent in my experience. My system consists of very high end electronics, speakers and subwoofers in a professionally treated room including massive bass traps and first reflections with cloud. In my experience, each time I went up the USB tier with Shunyata, there was a noticeable improvement in my audio playback. This was not subtle or where you have to "squint" with your ears to hear it. It was apparent quickly. I don't pretend to know why (reduced dialectic interference, etc etc) but I do know that companies spend their whole lives on the issue of transparent audio playback. I don't pretend to think everyone can hear these changes or even care about them. But when you run a professional mastering/mixing/recording studio like me, it is imperative I have the cleanest signal. And in my experience going from a standard USB to a platinum starlight from wire world, to a gamma Shunyata USB, to a theta USB to an alpha USB, each tier showed improvements. I base "improvement" around if I can hear in to the mix more, less masking, better transient unpacking, and better sense of realism (space, timing etc) Just food for thought. If you have a solid system @frank009 with a well treated room, I highly recommend trying your hand with different USB (or AES or Spdif whatever you use) and see what you hear (or don't hear) - your theoretical knowledge seems solid but I do believe there is a reason companies spend their entire existence trying to solve these problems. And it's not just to sell a $3000 USB cable to someone so they can laugh about it. They truly believe in the science behind their claims. And have a ton of real world experience to back it up. I won't be buying any $3000 cabling. But then again I don't have a million dollar system that may reveal these changes. Just sayin - sometimes it's worth suspending your disbelief and trying these things for yourself. If you're ever in central Virginia, I'd love to show you even the difference with a USB in my studio or upgraded coax in my living room. It's honestly not subtle. I believe your heart is in the right place (not wanting people to shell out funds for what you believe are sham companies) but also I think real world experience is important with this as the science of cabling can get fairly complex and there are many proprietary technologies that are being researched to address these issues! |
