Danger! Caution! : The text in this one says, for your information, what if you solder the contacts? but please do not solder to the terminals of products such as audio amplifiers, even if it is speaker cables and banana plugs or Y plugs, because there is a high possibility of breaking them. Please do not do this. Are there inexpensive speaker cables that do not oxidize? Answer: BELDEN speaker cables with tin plating seem to be resistant to deterioration over a long period of time. We hope that Hitachi and Furukawa Electric cables will also take a cue from this. Incidentally, cellulose nanofibers can be used for electric wires, speaker cables, and even as a substitute for optical fibers because they are transparent like glass. There are also technologies to paint or coat cellulose nanofibers so that only the surface will not rust. Cellulose nanofibers can be made to conduct electricity or not, depending on how they are mixed, so they can be used as a substitute for the carbon bodies of jumbo jets and automobiles, or to make semiconductors, batteries and capacitors called capacitors. However, for the highest performance semiconductors, diamond semiconductors made from alcohol seem to have the best performance.

I am just a music lover with no great interest in audio. I polish my speaker cables infrequently, but if possible, I would like speaker cables that, once attached, are semi-permanent or do not require care for more than a few years.

My ears have never felt any change in speaker cable material, nor have they felt any change in thickness. However, I do find it unpleasant when speaker cables oxidize to some degree, as the noise becomes more noticeable.

The tips of power cables are maintenance free and can be used for years. I wish there were speaker cables that could be used like that for years with no maintenance.

If you know of inexpensive, non-oxidizing speaker cables, or inexpensive, non-oxidizing cables that can replace speaker cables, please let us know.

Or if you know of a way to keep speaker cables from oxidizing over time, please let me know.

Thank you in advance.

Pure iron does not rust.

This is because the ease of rusting is determined by the amount of oxygen and impurities it contains from the beginning.

Therefore, speaker cables should also be made of oxygen-free copper with tin or silver plating.

I have been using OFC (oxygen-free copper) cables with tin plating for over 15 years.

And I've never thought about speaker cables.

I reconnected them the last time I moved and saw no degradation at all.

I think they are probably similar to these.

I see that oxygen-free copper is more rust resistant than the same copper wire. If oxygen-free copper is plated with tin, it seems to last much longer. Plus it's cheaper!

　I worked for a cable manufacturer for about 30 years and the only way a cable conductor can oxidize is

1) When moisture gets into the conductor

(2) When poor quality insulation is used.

(There are cords on the AV market with transparent PVC insulation that have obvious conductor discoloration...)

The reason for this is that the copper wire for cables is used by NTT, for example.

Copper cables for cables, for example, NTT telephone cables and power cables for electric power companies, are replaced after 20 to 30 years. The used cables are returned to the manufacturer, melt-cast again, and reused. When these recovered cables are disassembled, the copper wire in areas that were properly covered with insulation remains shiny. General-purpose cables have a life expectancy at the 20-30 year level.

In other words, as long as the person in question is using a cable of reasonable quality, noise caused by the cable will not occur in a few years.

　The problem is the part of the terminal that is exposed to the air. Since the connections to the amplifier and speakers are constantly exposed to air, the copper wire in this area will be oxidized and change color. As pointed out in the previous answer, it is a good idea to seal the terminals so that they are not exposed to air, and to periodically disconnect the terminals and reconnect them. Also, the screw terminals need to be properly secured by applying pressure to the copper wire, otherwise it will cause a real "clattering" noise.

The tip of the cable is a sooty color. Maybe the crimp is too loose. I am thinking of buying tin-plated cables, which I was told are resistant to oxidation, because it would be a hassle to strip and polish them anew after cutting them.

That's not some kind of oxidation of the speaker cables, but a (so-called) buzz in the volume of the amplifier, isn't it?　Or bad contacts in the amp. Or bad contacts in the RCA cables.

So why "polish the speaker cables and they will be back to normal again for a few months"? It could be that the contact is temporarily recovered because the amplifier is moved or pressure is applied to the back of the amplifier when the speaker cable is polished.

How often does "poor sound quality due to oxidation" occur?　In any case, cables whose tips frequently turn black should be replaced immediately. However, if the problem is on the amplifier side, that may not solve the problem.

You say, "The noise started within a year of purchasing the amplifier," but if you have used the amplifier before, how was it then? If you could also write down the model number of your current amp and cables, you might get a useful response.

Thank you for your answer.

The amp is indeed acting strangely, but that has only started in the last year or so. Sometimes there is no sound coming from the speakers. If I turn up the volume to a certain level, I can hear it normally. I bought the amp and speakers over 10 years ago. I did not have speakers or an amplifier before that.

The sound quality problem, which I believe is due to oxidation, occurs once every few months. I don't know the exact frequency, but I think it is more than twice a year.

The tips of the cables are sooty when they sound funny. I am thinking of changing the speaker cables to the oxygen-free copper tinned ones that others have responded to. It is certainly possible that there is a problem with the amp and it was fixed accidentally by vibration, etc. and I am mistaken. I think changing the cables and seeing what happens will be more revealing.

That is strange. You are of the sane understanding that you have never experienced any change in sound due to the cable, but you are experiencing noise due to oxidation? There must be some other cause. If you still think that the speaker cables are oxidized, why don't you use cables with gold-plated terminals? I think most audio stores carry them.

I am so into audio that I have bought more than 4000 titles of music software, but I have never experienced any problems due to oxidation of speaker cables. We use ordinary cables.

As an aside, I do not deny that cables can change the sound, but I believe that the change is slight and depends largely on the placebo effect. I think it's a placebo effect. Audio is a world of occultism, after all.

Thank you for your answer.

As for the change in the sound of the cables, whether it is an assumption of the person who bought them or who knows, it didn't matter to me because I can't perceive any difference and I'm not unhappy with my current cables.

Indeed, if you say that there is really a causal relationship between oxidation and my perception of noise, I can't prove it, and I may be misguided, but that's what I suspect. When I check the cable at such times, it is not shiny and somewhat sooty. I am sure it is my poor viewing environment. In any case, I would like to know how to prevent oxidation of the cables.

A child of my acquaintance is very sensitive to sound and gets scared in response to things like the sound of an ambulance that I don't hear. After a time I finally notice the sound too. So I believe that my ears are insensitive. If you have ears like that child, maybe you can sense subtle changes.

>How to keep speaker cables from oxidizing over time.

If you are concerned about that, I don't think it makes much sense unless you consider the terminal as well as the cable.

The best thing to do is to solder (or electro-weld?) directly to the terminals (or to the internal SP output terminal w of the amplifier). It would be quicker to solder directly to the terminal (or to the internal SP output terminal of the amplifier).

However, this is difficult to do in reality, so it would be best to wire the speaker cable longer, cut off the end at an appropriate time, and re-strip the cable.

Then, polish the terminals or clean them with a special agent.

I wish it wasn't so tedious to clean them from time to time, but it was a pain to reach behind the speakers and amps and remove the cables each time to polish them. I wish I could simply put them on and not have to take them off until they fail.

I still think it is not "oxidation of the speaker cable".

I agree with Mr. Yorkminster's detailed explanation about the basics of cables and terminals. (Thank you very much for your detailed explanation. ←Thank you very much for your detailed explanation.)

I think the cause of the "noise" is not after the output terminal of the amplifier, but either at the amplifier itself or at the input terminal.

In rare cases, if there is a speaker switch on the amplifier, the switch may have a poor contact. 、、、、

By the way, what kind of "noise" are you talking about?　I'd like to hear more about it.

Actually, the amp is already going crazy.

As for the noise, it started within a year of purchasing the amp, and when I polished the speaker cables, it would go back to normal for a few months. So I'm thinking it has nothing to do with the amp. The noise is like a rustling, and it is intermittent (or in certain parts of certain songs).

By the way, when something is wrong with the amp, turning the volume will fix it. No sound comes out of the speakers at that time.

Conclusively, it seems to me that a trip to the pharmacy and some anhydrous alcohol, a cotton ball and a cotton swab will take care of the problem.

I don't think that the oxidation to the point of "making noise" is simply due to exposure to air. Some sort of chemical reaction must be occurring at a significant rate.

As a possibility, are you touching the conductors with your bare hands when you twist the cable end or insert it into the terminal?　If so, sebum and other substances can adhere to the conductors, making them susceptible to oxidation and sulfurization. Or, if you are a heavy smoker and smoke purple smoke... The same is true for oil fumes from the kitchen. The same is true for grease fumes from the kitchen.

If this is the case, there is no point in treating the terminals. Wear gloves and degrease the cables and terminals with alcohol before connecting them. It is also a good idea to periodically wipe off any dirt with alcohol.

If not, please supplement the description of what kind of noise is produced and under what conditions.

Incidentally, the ends of power cables are usually made of bare brass or nickel-plated. Brass is an alloy of copper and zinc, almost the same as a 5 yen coin, so it rusts easily.

----------

When using a terminal tool, one plated with nickel, gold, silver, rhodium, palladium, etc. is suitable, but cheap plating is not good because it will erode through the gaps (which can be seen under a microscope) and the base metal will rust.

As for contact protectants, be careful, as they may damage resins and plastics in some cases. Too much can also have the opposite effect, as it can cause dust to stick to the surface. Basically, cleaning with alcohol is sufficient. Even if alcohol is used, it should be applied carefully and thinly with a brush, brush, or cotton swab, not by spraying.

Even the parts of vintage cables that are hidden by clothing are oxidized and sulfidized, and a lot of black stains can be removed by rubbing, so it is not worth buying if you assume that the surface will not deteriorate (if you need the sound quality from an audio standpoint, of course, that is fine). (although it's fine).

Thank you for your answer.

I see that sebum also has an effect. I was touching it with my bare hands. The noise is like a rustling. It disappears when I polish the cable. When that happens, the color of the cable is darkened.

The terminals of power cables also rust, don't they? I did not know that.

I see. So there is a difference in the quality of the plating. I guess I shouldn't solder them as an amateur.

For now, I will clean the speaker cables I am using now with alcohol and handle them in such a way that they do not get any sebum on them.

Nice to meet you!

I'm an audiophile, but I'm a purist of the pure type (lol), so I also use regular 15A wire. I use regular 15A wire. Furthermore, the parts I don't care about have been there for 5 or 10 years (laugh).

However　

(Laughs.) But, "The power cable..."

I would like to know about the specific cables and terminal treatment, as well as the shape of the terminals on the amplifier and speakers.

Since the word "noise" is used in the description, it may be due to something other than oxidative effects.

The ultimate connection method would be to solder or weld the amp (internal wiring section) to the speaker (internal wiring), but this is not practical, so I would like to consider the best method within practical limits.

Thanks for the answer.

I have had the speaker cables replaced to see if the sound changed, but I couldn't tell any difference. It seems that those who can understand it can. The inexpensive cables were sufficient for me. However, I do notice the sound when oxidation has progressed, so I was hoping that oxidation could be prevented.

I am a complete amateur and do not understand technical terms, so I used a term like "of the power cable". I wanted to write that it would be possible to prevent oxidation and make the cables maintenance-free. Sorry for the strange sentence.

The terminals are gold-plated and screwed in. There is also a hole on the screw for a banana plug. I use to strip the cable, drop the screw and crimp it.

The noise disappears when the oxidized part is polished well or the cable is stripped anew, so I think it is caused by oxidation of the cable tip.

I can't do any specialized work like disassembling the amp, so I would like to ask for some layman's wisdom.

Usually, copper wire is used for speaker cables because it has low electrical resistance and is inexpensive.

Gold is the only practical metal, but gold cables are unrealistic, so it is better to solder or crimp gold-plated terminals to the ends of speaker cables.

The easiest and cheapest way is to spray/apply a contact protectant.
