Technics SU-GX70 Grand Class Network Streaming Amplifier

The Definitive Living Room Audio Center

The Technics SU-GX70 Grand Class Network Streaming Amplifier represents the pinnacle of digital audio technology, seamlessly integrating video, audio, and music streaming capabilities into a single, sophisticated component. Designed for discerning customers who demand uncompromising sound quality, this network amplifier combines Technics' renowned full digital technologies with versatile connectivity options to create the ultimate living room audio hub.

Advanced Digital Architecture

At the heart of the SU-GX70 lies a fully digital amplification system that processes signals digitally from input to output, ensuring minimal signal degradation and precise transmission. The proprietary JENO Engine (Jitter Elimination and Noise-shaping Optimisation) has been implemented for the first time in an HDMI ARC (Audio Return Channel) on a Technics product, delivering unprecedented clarity in TV audio by eliminating jitter-induced degradation. The innovative LAPC (Load Adaptive Phase Calibration) technology achieves ideal impulse response by adapting to speaker impedance characteristics, flattening both amplitude and phase frequency characteristics for rich spatial expression previously unattainable in conventional amplifiers.

Premium Power and Purity

The Twin Power Supply Circuit System features dedicated power supplies for amplifier circuits, completely isolated from other components to eliminate interference. High-end electrolytic capacitors and a high-speed 130 kHz switching power supply ensure highly responsive power delivery and powerful speaker drive capability, outputting 40W+40W (8Ω) or 80W+80W (4Ω). The unique Pure Amplification Mode shuts off power to network and HDMI circuits, removing noise from devices or antennas for pristine music playback. Analogue inputs benefit from discrete amp circuits adapted from the flagship SU-R1000, featuring low-noise FETs, thin-film resistors, and premium capacitors.

Comprehensive Connectivity

Digital & Network Features: - HDMI ARC with low-impact video output for high-quality TV audio - High-resolution wireless playback via Bluetooth®, AirPlay 2, Spotify Connect®, Google Cast™ - Support for MQA, DSD (up to 11.2 MHz), FLAC, WAV and more at up to 384 kHz/32-bit - Optical digital (×2), coaxial digital (×1), USB-A, USB-B inputs - Ethernet and Wi-Fi (802.11ax) connectivity - DAB/DAB+/FM tuner

Analogue Inputs: - PHONO (MM) input for turntables - LINE inputs (×2) - PRE OUT for system expansion - Stereo headphone output (6.3mm)

With its load impedance compatibility of 4Ω-16Ω and frequency response extending to 80 kHz in digital mode, the SU-GX70 delivers exceptional performance across the entire audio spectrum, making it the ideal centerpiece for premium stereo installations.
