Evolution of the transmission speed and texture of the sound.
“USB cable” series cables which have been highly reputed till now have been further improved by changing the shielding from PE to a fluorine system resin and the damper material from cotton to pure silk (natural silk).
The result is an extreme improvement of the non-dielectric constant which leads to a further evolution of the transmission speed and texture of the sound.
Apart from a solid single-core PCOCC-A conductor, there is 100% shielding by the use of a copper-foil shield. We also have a Carbon SF tube which prevents exterior noise and radiation noise, plus an anti-vibration USB plug made from a solid block of 2017S air craft grade aluminum alloy as in the original models, however, the evolution of the new version is obvious.
Principle and structure
Did you know that the signal line and power supply line are installed together in parallel in all conventional USB cables?
It is widely known amongst audiophiles that the radiation noise of power cables affects signal cables and damages sound quality when a signal cable and a power cable are installed in parallel or come into contact with each other.
However, most USB cables available on the market do not have any countermeasures to these problems.
Furthermore, the power supply lines in USB cables transmit a large amount of ‘noise’ that is generated by the P/C (computer). This ‘noise’ seriously degrades the quality of the signal being transmitted and therefore, the audio sound quality is greatly reduced.
Attempts to shield one cable from the other (inside the same cable) is not effective in avoiding influences from the power line to the signal line.
Some high-end USB cables made by audio cable manufacturers have independently shielded signal line and power lines,
however, these two lines are in close proximity in the same cable and its shielding effect is very limited.
A world first! Perfectly separated and independent signal line and power supply line !
We took the initiative in the world by developing USB-1.0SPand USB-1.0PL equipped with two independent cables consisting of a two-core shielding structure with a 100% shielding effect obtained by using a copper foil.
This was the only USB cable which is successful in stopping noise interaction between the power and signal lines, and won a popularity.
Now, we have made further improvements on USB-1.0SPand USB-1.0PL and have released its evolved / improved type USB-1.0SPS and USB-1.0PLS.
We can obtain further improvements in sound quality by employing two A-Plugs.
We can obtain further improvements in sound quality by employing two A-Plugs to separate the Signal and power lines from the output terminals.
A very thick 0.8Φ PCOCC-A solid core conductor is used, fully exploiting the limits of USB connectors
USB-1.0SP and USB-1.0PL USB cables are equipped with a very thick
0.8Φ Solid single-core PCOCC-A conductor (the highest diameter USB cable currently available on the market) to achieve an overwhelming Dynamic range and Frequency range that was previously impossible to create by conventional USB cables.
The purity of PCOCC-A (annealed PCOCC which does not have crystal grain) exceeds the high purity copper such as 6N when it is made into a cable, and its overwhelming conductivity is far superior.
We also applied PCOCC-A as a solid single-core to avoid stray current(Strand jump phenomenon) and to achieve an accurate digital transmission, resulting in a clear and blur-less sound image, wide and deep sound field with an accurate phase and a full three-dimensional acoustic field.
Maximum technology without compromise for the terminals and also the cable structure.
Original USB plug made from a solid block of 2017S air craft grade aluminum alloy to improve vibration control effect.
Outer shielding with Carbon SF tube to prevent exterior noise, radiation noise generated from the cable and the electrostatic charge of the cable itself, leading to a perfect separation of the signal line and power supply line.
The connection between cable and USB plug is made with a high grade solder for audio use. It is not possible to use this solder for conventional molded USB cables.
You can order any length of USB-1,0SP and USB-1.0PL for your equipment.
As most conventional USB cables are molded cables, you are unable to order a specific length suitable for your use.
However, you can order any length of USB-1,0SP and USB-1.0PL for your equipment because our USB cables are fully handmade by skilled craftsmen.
