Stereo Integrated Grand Class Amplifier SU-G700M2 Black Colour
Technics announced the launch of the new SU-G700M2 Integrated Amplifier. This builds upon the platform of its successful and widely acclaimed predecessor, the SU-G700.
The new SU-G700M2 is a typical example of Technics’ untiring efforts to constantly improve even its most accomplished audiophile products. With the new
SU-G700M2, advanced technologies derived from Technics’ Reference SU-R1000 Integrated Amplifier were trickled down to set a new standard at this more affordable price point.
The SU-G700M2 inherits Technics’ full-digital core amplifier technologies, such as the JENO Engine (Jitter Elimination and Noise-Shaping Optimization) for highest signal precision free of jitter and distortion, and LAPC (Load Adaptive Phase Calibration) for optimal matching to any speaker.
The new SU-G700M2 also incorporates the following additional features:
- An Advanced Speed Silent Power Supply (AS²PS), incorporating “fast” semiconductor parts such as GaN (Gallium-Nitride) FETs and Silicium Carbide (SiC) Diodes for a much more reactive, efficient supply of current to the power stage for higher drivability of speakers. This approach was used for the power supply of the Reference SU-R1000
- Improved sound image and dynamic power, combining low distortion and high transparency with energetic drive, improved soundstage and precise focus of voices and instruments without sharpness
- A high-quality MC phono input stage (in addition to MM input) for direct connectivity to turntables with high-end MC pickup cartridges
- Phono Input Phase selector for optimised playback of mainly older vinyl discs recorded with inverted phase
- Volume and source knobs now have the aluminium “spin” texture also derived from the SU-R1000 Reference Amplifier for clear distinction from the original SU-G700
The finish options for the hairline-brushed aluminium casework are silver or black.

Advanced Speed Silent Power Supply
What’s more, a Super Low Noise Regulator is provided in the later stage. It prevents the decrease of regulation due to fixed switching frequency and impedes the mixing of noise component into high frequencies. The result is a low-noise and high-response power supply that maximises the performance of the digital amplifier.
Three-section Configuration
Low-noise PHONO Input
Class AA Headphone Amplifier
The SU-G700M2 uses a Class AA headphone amplifier with separate amplifier circuits for voltage amplification and current amplification of the audio signal. The voltage is amplified by a high-grade operational amplifier, the current is amplified by an operational amplifier with high current-supply capability, and the high-grade PWM signal output from the JENO Engine is converted to analogue with high precision, thus enabling headphones to be ideally driven. This makes it possible to reproduce music with low distortion and a wide frequency range no matter what the load impedance of the headphones is.
High-Grade Parts
Technics' exclusive block capacitor
The power supply unit for the amplifier features Technics’ exclusive block electrolytic capacitor optimised through scrupulous tuning, which was installed in the SU-R1000.
Large ground terminal
The large ground terminal accommodates a thick, large-diameter ground wire.
Brass speaker terminal
The screws used for securing the wires sending audio signals to the speaker terminals are made of nonmagnetic brass.
