The A1S pure Class A power amplifier, with an output power of only 20W (8 ohms), is a typical British sound system. Its tone is delicate, moist, warm, mellow, and full of charm, making it an excellent choice for listening to music. This machine is not very expensive, but its sound is sufficient to compete with many larger brands of HI-END equipment. After repeated listening and comparison, we decided to produce it and share it with everyone. The A1 has had a profound impact on audiophiles. For a long time, people believed that a power amplifier must be pure Class A to sound good, and that pure Class A must be hot enough to sound good. Because the A1 was so successful, its successor models, the A2 and then the A3, could not match its fame and status.
