As an audio engineer I can confirm that shielding is more important in a cable than whether or not it has gold plated connectors. Gold plated connectors don't really do much unless the connectors are worn down and don't make good contact in the first place, shielding actually does something for signal to noise ratio, especially for unbalanced and/or mic level(low level signal) and/or long cables. This is really only applicable for analog stuff for the most part of course.
Not an audio engineer, but I had unshielded (thin) cables in my home speaker setup. If the cables were positioned correctly, everything was fine. Accidentally move them even a little, and there'd be a huge amount of noise, due to power cables going near the speaker cables. Switched to shielded (thick) cables, and there's no noise ever.
You laugh, but I once had a Future Shop employee try to sell me an expensive toslink cable by saying it had electromagnetic shielding. I replied that it's light, for him to say that emp affect light. I laughed in his face, leaving with the cheap one.
That is true, but what a lot of people miss is the next part. Gold covered cables were better, before we created modern alloys. Now that cheap cable with a copper connector will tarnish slower than the gold cable.
Gold is non reactive. Gold plating still makes sense for analog cables, but not with digital ones.
With digital, the receiver is able to filter out the noise that a dirty connection might have. It will either work or not and it takes a long time for a moderately well made cable to get dirty enough with regular use to fail.
The meme should have been those 2k diamond hdmi cables or even the monster brand ones.
Just checked the cable prices as the article is from 2015.
So, the top of the line RJ45 12m cable is ... 13k€
ALERT!
tin foil hats only block 93% of harmful mindcontrolling alien beams. In regard, our new gold foil hats block 100% of these shenanigans. It happens that I own the last 5 sheets of Pure Gold Surface (tm) from our first batch. Please make an offer and possess one of these rare items that will protect you from dem damn xenomorphs on https://boulderbugle.com/gold-foil-hats-bcgfmtq8
Gold analog cables is certainly better than their cheaper counterpart because the connector is less likely to corrode and would maintain perfect contact after repeated connect/disconnect cycles. Gold HDMI cables however is complete scam.
Especially gold plated like in the meme. Solid gold isn't really worth it, but gold plated means a thin layer of gold at the point of contact. Less corrosion at the point of contact, a better electrical connection, fewer sound issues.
The problem is when they start selling digital cables that cost 10x as much and use exotic materials. First of all, digital has error compensation built into the protocols so even if one bit gets flipped occasionally, the numbers still add up and exactly the same data gets through. Second, as long as the cable follows the standard (say HDMI) even the cheapest cable will be indistinguishable from a really expensive one.
Had a buddy of mine that swore they were a game changer. Ended up spending hundreds or dollars replacing all of his audio cables and couldn't tell a difference
Nah, you need carbon cables... As anlog interlink, no change what so ever, as digital interlinks the bass seems smoother. (can't even think of a theory that fits there, but I'll take it)
