If you're not accustomed to the digital sound of digital amplifiers, and if you're listening in a small environment, such as a room spanning 10-30 square meters, the AM-P1M amplifier is highly suitable. Although its power output is modest, its sound quality is impressive, with a rich and full tone, excellent detail and overtones, and a warm mid-frequency that evokes a tube-like feel. It also consumes little power, with standby power under 10W, and produces very low noise. The all-aluminum alloy casing is also exquisite
The circuit utilizes an operational amplifier for voltage gain, with the output being a Darlington output transistor, adjustable to Class A or Class AB output states. The materials used are of high quality, including 718 military-grade resistors, German Red WIMA capacitors, and 15A imported power output transistors
The power supply used is a laptop power supply, and it is recommended to use a voltage of 19-24V and a current of 3A or more. The output power of the machine is not particularly large, with an output of 30W. However, when paired with a 3-4 inch speaker, it is sufficient for a room
