AD-3Dis positioned as a high-end dual-channel HI-FI class A combined power amplifier. It adopts fully balanced transmission and amplification methods, fully symmetrical, fully balanced, differential input to differential BTL (bridged) power output. Large dynamics, strong driving force, high slew rate, low harmonic distortion, low noise, good transient response, and high linearity.
Each channel uses 8 pairs of (Toshiba) high-power tubes, and the whole machine shares 32! The power section uses a giant high-quality ring with a continuous power of 700W and one bull and eight ruby filter capacitors with a total capacity of up to 80,000 microfarads, thereby ensuring the AD-3's huge dynamic response, calm and abundant volume, and wide-ranging sound Field effect.
