A1S Pure Class A Power Amplifier Hi-Fi 20W×2 2.0 Channel Stereo Home Audio Amp (Silver)

The A1S is a pure Class A amplifier providing 20W×2 (8) output power. With its characteristically British tonal signature delicate, warm, and melodiously smooth it delivers a captivating listening experience perfect for music lovers. It uses four 18000F/35V filter capacitors from Nippon Chemical's Black Diamond per channel, with a total filtering capacity of up to 144000F. The charging and discharging speed is exceptionally fast, enabling the dynamic response of the entire unit to be more rapid and the penetration deeper. To prevent switch on/off shocks and DC output protection, silver alloy contacts offer stable performance and extended operational duration, providing protection for the equipment. The left and right channels employ a pair of Ansem MJL21193/MJL21194 power transistors, frequently utilized in Swiss luxury high-end audio amplifiers. These transistors perform extremely well in terms of sound clarity, layering and detail resolution. As a set of audio-grade power transistors that enable fatigue-free listening for extended periods, they are ideally suited for AB-class and A-class amplifiers, boasting exceptional linearity. The power amplifier's strong motivation originates from the toroidal transformer, which has a strong power reserve. It is like the giant A-core uninterrupted transformer in a car's engine, providing a continuous source of energy for power amplification!
