Shengya A-203MK Signature pure class A amplifier represents Shengya company's comprehensive experience in developing design and manufacturing capabilities for transistor amplifiers. It adopts the fully balanced amplifier circuit recognized by many international advanced audio product manufacturers and enthusiasts, which makes the sound quality, sound color, sound field and control performance reach the peak.
Shengya A-203MK Signature is an upgraded product based on the original A-203MK standard version. It mainly uses Hi-END grade wires, terminals and electronic components for the audio-specific devices inside and outside the machine.
The core of Preamp's amplification section is a high-speed DC amplifier module chip developed with years of experience. It is characterized by wide frequency response, extremely low distortion, slim and thick sound, and dynamic and dynamic, surpassing many so-called advanced audio ICs. And the sound quality of discrete components. The volume control adopts the electronic volume control chip CS3310 manufactured by CRYSTAL Company of the United States, so that the error level between the channels is controlled within 0.5dB, which is much better than the ±3dB control precision of the quadruple mechanical potentiometer.
A ring-shaped high-power transformer with a shielding box is placed inside the machine. The whole transformer is filled with epoxy resin, which effectively reduces the vibration and noise interference generated by the transformer. Each channel power supply filter capacitor uses Japanese ELNA audio dedicated electrolysis. With a capacity of up to 120,000 microfarads and 32 high-power transistors, it consists of a 100W class A output stage. The tone is delicate and thick, it is powerful.
In order to match the performance of Shengya A-203MK Signature, the German WIMA brand MKP 10 specification and M-CAP brand audio special film non-polar capacitor, five-color ring high-precision metal film resistor, parallel precision power supply. The post-stage signal input circuit is composed of Toshiba field effect transistors and is formed by cascode differential amplification, and the Toshiba transistor is used for second-stage differential voltage amplification and current drive. The speaker connection terminal uses 8 German-made WBT brands, and the wire connected to the terminal uses the American LITON brand pure copper-plated speaker cable. The transformer power input line is changed to the US XLO power cord, and the fuse connected to it is also replaced with the German Vincent brand audio fuse. The internal DC low-voltage power cord is also switched to the US KIMBER audio dedicated wire. The DC stabilized power supply filter capacitor is upgraded to the Japanese NICHICON brand MUSE specification. The signal channel circuit uses the American DALE resistor to significantly improve the sound quality.
Shengya A-203MK Signature introduces a full-featured CPU control and data information screen is displayed, the senior HIFI amplifier entered the epoch-making digital technology field, in order to allow fans more convenient to use the machine, specially set up full-function infrared remote control system, The control effect of all data information exchange is realized.
Shengya A-203MK Signature amplifier design to reflect the main purpose of the product content, Bing abandoned the monotonous rough style high power amplifier, the way to take the overall shape and details of the interaction scored, it has a post-stage power symbol There is also the control charm of the pre-level, which solves the problem of the post-level rigidity of the high-power merger machine. The cover of the case is also changed from the original silk-screened text to the engraved aluminum plate text, which has been distinguished from the original standard plate. In today's world of silver-loaded machines, boldly adopting black and decorating it with a small amount of aluminum-white white parts not only enhances the visual impact, but also creates an unprecedented glamour, stability, and overall relationship with the details of the black. Very exciting, wonderful and very eye-catching.
