  • Description
This machine is equipped with 16 pairs of Toshiba 1943/5200 by default

Appearance: It exudes a noble and imposing aura, yet remains fashionable. With its gold brushed panel and professional-looking handles, coupled with dual dynamic needle indicators, this appearance would typically be found on foreign watches costing over 30,000 yuan.
Sound quality: Magnificent and grand, the A60 boasts a 20W pure Class A amplifier. Its vocal and instrumental reproduction is superb, with excellent bass extension and airy sound. However, it's not your typical Class A amplifier. While typical Class A amplifiers tend to distort when exceeding 20W, the A60 automatically switches to a 200W Class AB driver when the power output exceeds 20W, ensuring the loudspeaker remains in excellent condition and delivering a dynamic and powerful sound.
Technical highlights: Input: The circuit adopts a fully symmetrical architecture with current feedback. The main feature of this circuit is the use of complementary push-pull circuits from the input stage to the output stage, which can easily achieve a slew rate of hundreds of volts per microsecond. It has excellent driving capability for capacitive loads. The output utilizes 16 pairs of power transistors in parallel to achieve very high driving force and very low output impedance, easily driving speakers with a load of 2-8 ohms.
