Features

Three-section Configuration for Clear, Distortion-Free Sound

The SU-G700M2 integrated amplifier is built for superior sound quality. By using a unique three-section design with dedicated partitions between different circuit blocks, it reduces interference and distortion. This setup ensures that both delicate input signals and high-power output currents are kept separate, so you experience clearer, richer audio every time.
Three-section Configuration for Clear, Distortion-Free Sound

Experience True-to-Life Sound with Load Adaptive Phase Calibration (LAPC)

Every speaker responds differently across frequencies, but the SU-G700M2’s innovative design ensures your audio remains clear and consistent. Unlike conventional amplifiers, which are impacted by speaker impedance and lose audio fidelity, this model uses an advanced adaptive optimization algorithm. It automatically adjusts for each speaker's unique characteristics, balancing frequency, amplitude, and phase for a smoother, more accurate sound. The result? A rich, immersive listening experience with detailed, spatial audio that fills the room.

Crystal Clear Audio with JENO Engine Advanced Digital Amplification

To deliver every detail of your music without compromise, the SU-G700M2 uses a state-of-the-art JENO Engine for full digital amplification, inspired by high-end reference systems. Unlike traditional digital amplifiers, this model solves common audio quality issues caused by jitter (timing errors) with a proprietary jitter reduction circuit that ensures pristine sound across all frequencies. Plus, a specially designed high-precision PWM conversion circuit optimizes every detail, preserving the dynamic range of high-resolution audio for lifelike clarity. With these technologies, you’ll enjoy natural, finely detailed sound that captures even the subtlest nuances of your music.

Powerful, Pure Sound with High Speed Switching Silent Power Supply Technology

The SU-G700M2’s upgraded power supply, inspired by our reference-class SU-R1000, delivers stronger speaker drive and richer sound. With a higher switching frequency of 400kHz and advanced GaN FET and SiC SBD components, it reduces noise and stabilizes power for clearer audio. The Super Low Noise Regulator minimizes interference, ensuring a clean, high-response power supply that maximizes the digital amplifier’s performance. Enjoy fuller, more dynamic sound with exceptional clarity.
