Description

CLASSIC REGRESSION】The A1S is a pure class A amplifier, with an output power of only 20 W (8 ohms). This device is a typical British sound, with delicate and smooth sound, warm and mellow, and full of charm, making it a good device for listening to music.
【LARGE CAPACITY MAIN FILTER ARRAY】Using Siemens 8100uF 63 V filtering capacitors with 4 per channel, the total filtering capacity can reach up to 64800uF and the charging and discharging speed is extremely fast, which can make the whole machine's dynamic response faster and dive deeper.
【OMRON RELAY】To prevent switch on/off shock and DC output protection, silver alloy contact shave a long service life and good stability, providing protection for the equipment.
【ANSEMY POWER TRANSISTOR】The left and right channels each use one pair of Ansen MJL21193/MJL21194 large tubes, which are often seen in Swiss luxury amplifiers.The vocal/level/detail performance is very beautiful, and the overall performance is not comparable to that of Toshiba and San ken tubes. lt is a beautiful sound large tube that is not suitable for AB and A class amplifiers, and the linearity is very good.
【LARGE RING TRANSFORMER】The powerful power of the power amplifier comes from the Huanniu 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!
