A-203MK Signature pure class A amplifier represents our company's comprehensive experience in developing design and manufacturing capabilities for transistor amplifiers. It adopts the fully balanced amplifier circuit recognized by many international audio product manufacturers and enthusiasts, which makes the sound quality, sound color, sound field and control performance reach the peak. 
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 the preamplifier 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 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. The capacity is up to 120,000 microfarads, and 32 high-power transistors form a 100W class A output stage. In addition to the delicate and thick sound, the tone performance is also strong. 
In order to match the performance of the machine, the German WIMA brand MKP 10 specification and M-CAP brand audio special film electrodeless capacitor, five-color ring high-precision metal film resistor, parallel precision power supply. The post-stage signal input circuit is composed of Toshiba FETs, which form a cascode differential amplifier, and the Toshiba transistor is used for the 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. Signal channel circuit uses American DALE resistor 
To significantly improve the sound quality performance. 
A-203MK Signature introduces the CPU full-featured control and data information screen display mode, which makes HIFI power amplifier enter the epoch-making digital technology field. In order to make the fans more convenient to use this machine, the infrared full-function remote control system is specially implemented. The control effect of full data information exchange. 
The design of the A-203MK Signature amplifier is designed to reflect the main purpose of the product. It rejects the monotonous and rough style of the high-power amplifier, and adopts the interaction between the overall shape and the detailed characterization, so that it has the power symbol of the latter stage. There is a pre-level control charm, which solves the problem of high-level merger machine modeling and post-stage rigidity. 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 makes black a charm, a steady atmosphere, and the relationship between the whole and the details is very exciting. Beautiful, very eye-catching.
