The Unstoppable trend- USB HiEnd
The USB DAC device should be the most popular choice for most of users as it has two advantages that no one would deny. 1. Convenience – As almost everyone’s PC or Mac should have the USB port, using USB DAC will be very easy for all PC users. 2. Cut off the noise – The most reason for audiophile reject using the computer as source because it might have ripple, noise, high frequency radiation, jitter, and unstable power voltage output. All these problem will cause music with noise and unclear background none of these could be endured. As the USB DAC is external device, it will decrease the affection from the PC substantially. No loss or no distortion is the most important thing while signal transition. The USB cable will play very important role when signal transition.
The characteristics and benefits of cryogenic treatment
Cryogenic treatment is the process of treating work pieces to cryogenic temperatures (i.e. below minus 196 degree C or minus 320 degree F). It is a programmable treatment developed in the past 20 years by Jeff Levin (with a PhD in physics) of MIT and R. F. Barron (with a PhD in metallic material science) of University of Louisiana to remove residual stresses after annealing and other processes on steels. In the treatment, liquefied nitrogen is used to lower the temperature of a work piece to minus 196 degree C and maintain such temperature for a period of time; then, temperature is brought up slowly through programmable control to the room temperature. Such treatment would change and improve the fine-grained internal structure and the density distribution of a work piece; in addition, impurities (such as minute carbides) are removed. Such treatment can make a work piece more stable and more durable. According the relevant research, the mass ratio of a metal depends on different low temperatures and the minus 196 degree C is the optimal low temperature to reach the goal of the most stable mass ratios of metals. With the treatment of such temperature, the molecular structure may become tidier, the density may be increased by the removal of the minute carbides and hence the work piece may be strengthened. Moreover, the treatment may be used to treat work pieces that have been formed without causing any deformation and discoloring.
Furthermore, with regard to the transmission of musical signals, because musical signals travel along the surfaces of a musical instrument or a musical component, the surfaces may become smoother due to the removal of impure minute carbides along the surfaces. In other words, the effectiveness of the transmission of musical signals would be improved substantially. Therefore, in the upshot, a better effect of musical signal transmission may be achieved with the treatment.
Power is everything
Power means a lot –dynamic, 3D images, purity all relates power. Many audiophiles might have very similar experience – after exchange multiple gears or cables, there is no much improvement for its sonic performance. After using better power supplier unit or even power distributor, the sonic performance improved immediately.
All things relate to power!
Why DC power is the best?
Pure DC power is the best power source for the Hi End. However, it is really difficult to provide pure DC for high watt power amplifier as the huge capacitor (battery) size or large power capacity demanding.
Why use separated DC power for USB DAC?
The most reason for audiophile reject using the computer as source because it might have ripple, noise, high frequency radiation, jitter, and unstable power voltage output. All these problem will cause music with noise and unclear background none of these could be endured. As the USB DAC is external device, it will decrease the affection from the PC substantially. After using power separated USB cable, it means all the ripple, noise, high frequency radiation, jitter, and unstable power voltage output will be fully cut. The sound will be clear, the frequency range will be even complete, the image will be even more vivid. Why not try it by yourself?
The advantage for signal/power separated design and the advantage for the pure DC power supply unit.
The Kingrex UPower has a completely new design and guarantees perfectly clean DC current from its two output connectors.The 7.5V input connector directly connects to the two 3.75V Sanyo quality Lithium-ion cells in series.The 5V output is generated by dropping a 7.5V current through a linear regulator without the use of any switching power circuit.
The power voltage and current supply is very important for operating the power amp which could affect the sonic performance directly. Even if providing the pure DC to the DAC which only required small current output, it will still show the significant improvement.
