Kimber Kable is a company that specializes in the making of sound and lighting founded by Ray Kimber in around the 70s and it is located in Los Angeles. What we see now in clubs and concerts with colorful flashing lights that dance to the rhythm of music is what was initially experimented on different metal conductors. Kimber Kable wanted – and even in the present time – to test the outcome of what each conductor produced with regards to the size, lengths, insulation, and twisting of the wires. Kimber Kable combined both sound and light to create the very first discotheques big enough to illuminate and boom up a whole room.
A little forum or topic of discussion started to roam around the web when Kimber Kable promises “to preserve the delicate data stream” in a newly designed USB cable. According to the Kimber Kable hypothesis, this USB is supposedly unique in transmitting audio to produce that originality for audiophiles. The question is does USB not transmit digital information, so why is there a need for a ‘special’ cable to transmit audio and does it improve the quality of the sound?
USB cables, in general, are designed to withstand high-performance when connecting 2 technological devices or to a PC, similar to a FireWire. As such, Kimber Kable released a USB silver wire conductor, but also a USB copper conductor which is the much affordable version. The silver conductor is made of polyethylene dielectric with a high level of concentration and wrapped in a layer of copper that has been plated in a silver coating. But does this provide that ‘special’ sound for audiophiles?
A research was done in measuring the audio output from the ‘special’ USB cable connected to the Topping D90 DAC (which is known to be one of the best) and another test using a normal cable on the Topping D90 DAC. The result of the ‘special’ USB cable depicted the relation of the distortion and noise to the core signal, which further shows that the absolute magnitude level in the audibility at 121 dB is at least 5 dB better. In turn, a -130 dB produces greater distortions. The result of the normal USB portrayed static outcomes as the ‘special’ USB, with 4.058 V, the voltage output is the same, at 1.0 kHz, the frequency is unchanging and the distortion at 0.000094% is identical.
The connection of a USB and PC can is the reason for noise to travel vice versa, therefore, there is a form of digital analog to this audio communication. However, the verdict is that the above-mentioned experiment shows that Kimber Kable’s hypothesis was null and void. For the reason that if it was an analog cable with good a shielding protecting it from external noises, then the distortion and noise would have changed during the experiment.
One of the qualities of digital information is that it is original and the copies are equal, unless the copy is corrupt, but, if a copy is to be corrupt, then the transmission protocol should be able to detect it. Therefore, as long as the external noise does not corrupt the bits, which is linked to the protocol – thus being detected and protected from the start – then there is no need for a ‘special’ cable to obtain that ‘better’ sound.
For a jaw-dropping and gasping price of $50 for half a meter and $115 for 5 meters, one would think to oneself whether or not this is the only way the manufacturers can obtain their income. This is quite an opportunistic approach. There are various con artists in the world, within the internet world, there are ‘con merchants’, they would prefer to advertise their products in such a way that persuades people into taking the bait on the hook. A cable that costs that much can score you around 50 cables for that exact same price, maybe you could even get change back after purchasing 50 cables.
So, what is the reason as to why anyone would be fooled to purchase a cable that costs that much? Would it be the quality of the cables? Maybe it could last longer than normal cables when talking about durability? Could it also possibly be that the speed transferred from one device to another (or a computer) is faster than the speed of light? Would purchasing USB cables made by Kimber Kable be worth the money and does it operate better than a normal USB cable?
