Is the audio better or are our minds playing tricks on us?
Power cables have the primary function of connecting your electrical device to a power source. While some believe that different cables make a difference to the sound quality of a television or hi-fi system, this is simply not true.
There is no scientific connection or correlation to sound performance based on the cable you use. But, some people swear that they can hear a difference in sound between different power cables. Let’s take a look at why.
Power Cords and their Functions
As we have already mentioned, power cords serve one purpose and one purpose only. That is to power your television, home theater system, or hi-fi unit. While power cords are available in various lengths, thicknesses, and types, they do not influence the sound achieved by your electronics.
Why, then, do some people swear that they can hear a difference in the sound quality when switching cables? Scientists and researchers have once again come to the rescue and conducted the research behind this phenomenon.
Their studies noted that auditory memory does not last long enough for the actual difference in sound to be noted and that it is likely a placebo effect that makes the different power cords sound different for these people.
When changing a power cord, there is no change to the volume, sound quality, or distortion levels of your television, speakers, or hi-fi.
There are, however, benefits to choosing the best audio power cable.
Choosing the Best Audio Power Cable: Tips and Tricks to Follow
Power cords are available in a wide variety of different lengths and thicknesses and are priced from as little as only $10 to as much as a whopping $1500. Depending on where you live, they are found at all hardware, electrical, and even grocery stores.
Choosing a power cable is fairly easy. Let’s look at the factors you should always consider when selecting a power cable to power your devices.
1: Length and diameter of the power cord
The length of your power cord should be chosen based on the distance between your television or hi-fi and your wall socket. Choosing a longer cable might seem like the best idea, but this can lower the resistance of your cable. Select a cable that is a perfect fit with a few inches of leeway.
Diameter really has no bearing, but thicker cables are known to be more resistant to damage and breakage. Choose a thicker cable for strength and durability.
Safety is, of course, one of the vital factors to take into consideration when buying a power cable to power your electronics. While it might seem like a great way to save a few bucks by buying a store-brand cable, power cables need to be certified to be safe.
UL certification is the safety standard for all American power cords. These cords are less prone to causing an electrical fire or shock and are well insulated and safety-tested. Always choose UL certification power cords.
Most home electrical fires are caused by short circuits, faulty plugs, and wiring. Using UL-certified plugs, power cords, and accessories can significantly reduce the risk of these events. You can check to see if your power cord is UL-certified by taking a look at the product packaging or contacting the brand’s customer service department.
3: Plug Type
America and Europe most commonly use three-terminal plugs. While some appliances and electrical goods have two-terminal plugs, the main thing to look out for is a grounding or earth wire.
This wire prevents electrical shocks and short circuits from occurring. Ask a store assistant to help you ensure that your power cord plug has a grounding wire; if it doesn’t, move on to another power cable or plug type brand.
4: Power Output or Specifications
Take note of the peak power output of your electronic device when choosing a power cord. Ensure that the cord you choose meets the requirements of your device and does not overload your device, thinking that it will improve the quality of sound.
This information can be found on the back of your television, home theater system, or hi-fi unit, as well as in the product manual for each of these. Safety should be your first concern when choosing a power cable and your decision should be based on the output requirements or specifications.
When to Replace Your Power Cord
Power cords are fairly hardy and age well. There are not many reasons to change your power cord. As we have already determined, a power cord has no bearing on the sound quality, volume, or performance of your television, home theater system, or hi-fi. If one of these is not working correctly, it is most likely an internal problem, not the power cord.
You will only need to replace a power cord when:
- The current cord is worn through, broken, or damaged.
- You need a longer cord to move your appliances and electronics around.
If you want to replace a power cord, you need not choose the most expensive one. The price of a power cord is influenced only by the UL certification and the brand. More well-known brands will cost more than their generic store-brand counterparts but have almost no influence on the quality.
You can choose the best power cord for your electronics by referring to our buyer’s guide and tips above.
The mind is a powerful thing. While many people swear that there is a difference in the sound quality when changing the power cords of their television or hi-fi, scientists have quashed this and put it down to the brain creating a placebo effect.
Auditory memory does not last long enough to create a noticeable difference.
Choosing a power cord based on its quality is, however, important, and a few factors affect the quality of your power cord. Read our tips and tricks above to choose the best power cord for your television, appliances, and other electronics, and remember to look out for that all-important UL certification.
