Pure class-A power amplifiers with rich expressions are irreplaceable products; they take audiophiles' hearts and won't let go. Accuphase has been developing over 20 models of pure class-A power amplifiers reflecting the latest technologies on a moment-to-moment basis. The A-300 is the ideal power amplifier that aims to surpass the sound quality and electrical performance of the A-250 launched in 2017. The A-300 achieved the unprecedented low noise characteristic and high output power with the latest technologies and accumulated knowledge cultivated in the flagship model development.

The digital power meter shows the actual output power without any effects of speaker impedance. An LED bar graph displays output power calculated from the output voltage. The gain selector on the front panel allows the user to select the appropriate gain level from four settings: "Max, -3dB, -6dB, and -12dB ". This gain switching is achieved by controlling the gain of the input amplifier section rather than attenuating the input signal with an attenuator. Therefore, the A-300 can reduce the residual noise by selecting a lower gain position. Two pairs of large speaker terminals offer beneficial biwiring connections with loudspeakers.

It contains an intense power supply, a massive specialmade high-efficiency toroidal transformer, and two sizeable 100000μF special-made filtering capacitors in the unit's center. The major difference between the A-300 and the A-250 is the position of the power transformer and filtering capacitors. The A-300 placed the power transformer away from the input amplifier, which helped to minimize the influence of leakage flux from the power transformer.

The A-300 enhanced the class-A operation area by 25%, as 125W into 8Ω load. Rated output power is double when the load impedance becomes 1/2; it reaches 1kW into a 1-ohm load.
