Misunderstanding In The Audio Cable

- Apr 03, 2020-

The sound quality reproduced by the audio system, in addition to the equipment itself and the combination, also has a lot to do with the acoustic characteristics of the listening environment, cables, accessories and the placement of the speakers.


Regarding fever cables, audio cables, digital cables, speaker cables and power cables are mainly used in audio systems. There are many varieties of these wires in the market, and the advertising is even more dazzling. Many wires are even mythical, which makes people have too many expectations and fantasies about the fever line. In fact, there are a few big misunderstandings here.

Myth 1


Blindly superstitious of the power of advanced wire, regardless of the condition of your own equipment, I think that if you change the good line, the sound effect will suddenly improve.


In fact, if the equipment cannot reach a certain quality, it is equivalent to an insurmountable bottleneck. Even the use of top-grade fever wires will not fundamentally improve the performance of the equipment. It is better to simply upgrade these costs to buy advanced wires. The equipment itself, even from the room's acoustic treatment or speaker placement, will be much larger than replacing expensive high-grade wires.


Myth 2


High-grade wire, only the icing on the cake, can not turn the tide.


For signal lines and speaker lines, many people use lines to tune the sound. Although different wires have a certain effect on the sound of the equipment, in fact, the characteristics of wire dyeing are used, because the wire itself is a passive signal channel, it is only a signal transmitter, it does not have the ability to amplify the signal. For example, if the low frequency of a certain device is not good, look for a cable with more low frequency. It sounds that the low frequency is strengthened. However, this is obtained by the attenuation of the high frequency signal by the cable. The response becomes uneven, so that you lose more than you pay.


Therefore, you should choose a neutral, low sound dyed wire. This kind of wire will not affect the performance of other equipment, easy to match with other equipment, so as to truly realize the potential of the equipment.


Myth 3


Underestimated the impact of the power cord on the equipment.


Many people do n’t agree with the impact of power cords on equipment. In fact, although the length of power cords is very short for the entire power grid system, the cross-sections of power grids connected to the wall are generally large, while the cross-sections of ordinary random power cords are small. The small diameter of any part in the middle of the wire will become the weakest link in the entire circuit, which will become a factor restricting the power supply. In addition, professional power cords also have multiple layers of shielding, which can reduce the impact of interference in the power supply to a certain extent.


Myth 4


Silver wire is better than copper wire.


Although silver wire has low impedance to high frequency and better transmission than copper at high frequency, it is sometimes excessive and low frequency performance is poor. Pure silver wire is not only expensive, but also easily oxidized, so it is relatively rare, most of which are silver alloys of other metals.


The copper wire is more uniform for high, middle and low frequency transmission, but pure copper has more impurities and more crystals, which is not suitable for making audio wires. Nowadays most of them are OFC oxygen-free copper. Due to the reduction of impurities, the sound tends to be clear and transparent. With the improvement of smelting and annealing technology, large crystalline oxygen-free bodies and single crystal copper have appeared, making the transmission of sound more balanced.

It can be seen that playing the line must be cautious and not blind. The wire is different from other equipment, it is not classified, and it is not the same as the so-called best wire. Find out the characteristics of the wire, make the best match between the wire and the equipment, and the cheap wire can also produce a satisfactory sound.
