A1S Pure Class A Power Amplifier 20W×2 2.0 Channel Stereo Amp | Reference classic circuit | Compatible with desktop and bookshelf speakers | Color: Silver

RETURN OF THE CLASSIC: The A1S is a pure Class A amplifier delivering 20W+20W (8) output power. It features a classic reference circuit with a characteristically British tonal signaturedelicate, warm, and melodiously smoothproviding an engaging listening experience ideal for music enthusiasts.
LARGE CAPACITY MAIN FILTER ARRAY: It utilizes 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 remarkably fast, enabling quicker dynamic response and deeper penetration.
EQUIPPED WITH OMRON RELAY: To prevent switch on/off shocks and provide DC output protection, it uses a relay with silver alloy contacts known for stable performance and long operational durability, offering protection for the equipment.
ANSEM POWER TRANSISTOR: The left and right channels employ a pair of Ansem MJL21193/MJL21194 power transistors, frequently used in Swiss luxury high-end audio amplifiers. These transistors perform exceptionally 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 outstanding linearity.
LARGE TOROIDAL TRANSFORMER: The power amplifier's strong motivation originates from the toroidal transformer, which has a substantial 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!
