Technics SU-G700M2 Grand Class Stereo Integrated Amplifier

Technics SU-G700M2 Grand Class Stereo Integrated Amplifier The Technics SU-G700M2 is a Grand Class stereo integrated amplifier engineered for listeners who want the precision of advanced digital amplification without giving up serious analog connectivity. Delivering 70 watts per channel into 8 ohms and up to 140 watts per channel into 4 ohms, the SU-G700M2 combines Technics' JENO Engine, Load Adaptive Phase Calibration (LAPC), a high-speed low-noise power supply, and a premium MM/MC phono stage in a substantial aluminum-and-steel chassis. Designed as the successor to the acclaimed SU-G700, the M2 incorporates technologies derived from Technics' Reference Class SU-R1000. The result is an amplifier built to drive demanding loudspeakers with control while preserving low-level detail, precise imaging and dynamic contrast from both analog and digital sources. JENO Engine Full-Digital Amplification At the heart of the SU-G700M2 is Technics' JENO Engine—Jitter Elimination and Noise-Shaping Optimization. Rather than relying on a conventional analog signal path through the power stage, Technics processes the signal in the digital domain and uses high-precision PWM conversion to reduce jitter and preserve fine musical information. The SU-G700M2 provides an FTC-rated 70W + 70W from 20Hz–20kHz into 8 ohms, with output capability of 140W + 140W into 4 ohms under Technics' specified test conditions. LAPC Speaker Optimization Load Adaptive Phase Calibration (LAPC) measures the electrical characteristics of the connected speakers and applies digital correction to optimize the amplifier's amplitude and phase response for that specific load. This helps the SU-G700M2 maintain consistent tonal balance, spatial definition and transient response across a wide range of loudspeakers. Advanced Speed Silent Power Supply The M2 version adopts power-supply technology derived from the Reference Class SU-R1000. Its Advanced Speed Silent Power Supply uses high-speed switching, including GaN FET and SiC components, together with a Super Low Noise Regulator to provide fast current delivery while minimizing high-frequency noise. A rigid three-section internal construction separates major circuit blocks to reduce electrical interference and vibration. The chassis combines layered steel construction with a substantial aluminum front panel for additional mechanical stability. MM/MC Phono Input for Serious Vinyl Playback Unlike many modern integrated amplifiers, the Technics SU-G700M2 includes a dedicated MM/MC phono input. The low-noise phono circuit supports moving-magnet and moving-coil cartridges, with adjustable MC gain so the amplifier can be matched more closely to different cartridge output levels. This makes the SU-G700M2 a strong centerpiece for a high-performance vinyl system without requiring a separate phono preamplifier. High-Resolution USB DAC and Digital Inputs For digital sources, the SU-G700M2 includes USB-B, two optical inputs and two coaxial digital inputs. Its asynchronous USB Audio Class 2.0 connection supports PCM playback up to 384kHz/32-bit and DSD up to 11.2MHz, making it well suited for a computer-based high-resolution audio system or an external digital transport. Two analog line inputs, line output and preamp output provide additional flexibility for integrating source components, recording devices or external amplification. Class AA Headphone Amplifier A dedicated Class AA headphone amplifier uses separate voltage- and current-amplification stages to drive a wide range of headphones with low distortion and wide bandwidth. The front-panel 6.3mm headphone output makes the SU-G700M2 equally useful for private listening and loudspeaker playback.
