The video is talking about capacitance, showcased for increased effect by using a capacitor.
A capacitor works on the basis of two conductors divided by an insulator.
So two pieces of tinfoil with paper between them is a capacitor, two cables running next to each other are a capacitor, etc.
A capacitor resists the change in voltage. So when your goal is to do a change from 0 Volt (A) to anything that is not 0V, say 10 Volt (B), any capacitance in the circuit will act to resist that change.
The same applies when changing from a higher voltage to a lower one (C).
Cable capacitance is a thing, the most obvious example of this is some of the DIY speaker cables that use massive braids to try and remove RF noise, the most popular recipe I know of is a 96 strand braid.
These are extreme low resistance high capacitance cables, to the point they won’t actually work on some amps.
It’s trivial to do tests on cables that will show differences in RF rejection, or measurable differences in resistance or capacitance.
Like many things, with cables I’m in the Steve Gutenberg camp of listen and make your own determination.
I still don’t get it.
How the tin or what ever capacitance , get’s involved or effects with the plastic covered copper or silver…?
That was the question. @MazeFrame@Polygonhell.
Signals goes in the copper, that is covered with plastic. That plastic is covered by the shielding brands and etc material.
Not talking about shitty DIY shit. Just standardized cable that is shielded.
The point is that the signal or audio does not change and you talk that it changes.
In an ideal world, a conductor is a connection between two points with infinite current carrying capacity, zero resistance, zero capacitance and no interaction with the surrounding components.
In reality, a conductor has resistance, capacitance, inductance and emits or recieves E and B fields.
There is no “shitty DIY” here, just physics being what they are.
It creates capacitance. How much? That depends. In my opinion not enough to be audible but I don’t think I have golden ears and others may hear the differences. Capacitance cuts off lower frequencies (capacitors are what’s used in speakers to remove low frequencies from tweeters).
Research capacitors and capacitance to understand how this works and why cables can do this.
Thank you. I knew it cannot be that hard to answer.
Still Pro-grade cables do not have any issues. Shielded or not shielded.
Shiddy cable for sure and might have issues.
And BTW we’re talking theoretical on the capacitance as most speaker cables tend to be less than 20 feet in length, the numbers to make audible differences usually are in the hundreds of feet, but capacitance and inductance are real and are a part of any cable. That’s why the preponderance of evidence shows that all you need is a quality pair of 12 gauge twisted pair cable. Anything more than that will help… or hinder.
Manufactures that provide detailed measurement of their cables should be a minimum if you’re going to be spending hundreds or thousands of dollars into cables.
I think when we talk cables though it’s important to specify what type of cables and their purpose. Shielding an RCA cable that may be routed close to or next to an AC power cable is a good thing.
Yes. It’s still kinda stupid to even talk or mention about it. imo
They literally make cable that can be used hundreds of feet and zero issues if the cable aint faulty.
Bloody gesus might as well and easily shoot down and piss all over your shit and then it would be the holiest cable.
We would still argue over how much vitamin B it had. Pointless. It’s holy piss.
Point of view.
As I mentioned before, that’s why I don’t like to discuss or mention cables. It’s all based on your own sense of value and if you can hear any differences. Otherwise, it becomes argument for argument sake and I know @Marzipan knew this when he created the controversial topic.
Again, you just need to try for yourself. Personally, I started with Polk speakers and BL03 IEMs. I was using Amazon/Mediabridge/Monoprice cables. I couldn’t hear a difference. Phew, saved some money. Again, I was hoping to hear no differences.
But, when I upgraded to Harbeths and high-end IEMs, can I hear a difference now? I didn’t want to, but certainly. Am I going to recommend everyone to buy expensive cables for their use case? No.
Find out for yourself and don’t argue for argument sake.
Honestly I’d rather you hadn’t started it, your not going to change minds, so what’s the point?
Veritas’ last statement is the most useful in the whole discussion.
Lets open a bigger can of worms then, cheap china usb cables/amazonbasics/your usual 5 doller cables introduce quite a fair bit of distortion such that the dac’s garbage collector has a hard time phasing the digital signal and has to do more interpolation resulting in lost in quality.
I find that geting a nice usb cable besides ecstatics certernly helps in getting a better overall sound. On the other hand I’m not convinced on the digital side you can actually get any tonality shifts unlike on the analogue side.
That being said honestly I do wish that all analouge cables sound the the same so I dont need to to chase the dragons tail and just get quality interconnects. The blessing and curse of having access to cable demos lol.
All in all its my personal opinion that after you have your endgame setup the first thing to get is a well made properly insulated usb cable as that usually cleans up the sound without screwing your tonal balance.
Yeah but you said specifically “expensive cables are nothing but snake oil”
As if your word is final and correct lol instead of just being your opinion . I’m sure you knew it would erk someone when you posted it. So to now say that you made it for civilized discussion seems false. Specially since you could have worded it from a more neutral perspective.
Personally I don’t mind chaos and pissing people off so keep doing your thing. Also you äre using measurements as your only argument but do you believe measurements are the end all and be all with dacs and amps too?
and I never said my word was final. and just because something can be a hot topic doesn’t mean it will be a negative one.
I’ve thoroughly enjoyed the measured responses, even by those who are buying cables that cost more than most…which still aren’t expensive, compared to what is out there.
couldn’t help myself. Actually I’ve never listened to a good vinyl setup. Just stirring the bees lol.
