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?)
