Technics SU-GX70 Network Amplifier
The Technics SU-GX70 Network Amplifier Inherits the reference-class audio technology concept Technics employed in the reference SU-R1000 amplifier, the JENO Engine (Jitter Elimination and Noise-shaping Optimization) transmits and processes audio signals in full digital and with minimal jitter from the input stage to the power stage for highest signal purity.
Supreme Audio Performance
Designed to deliver reliably crisp, clear, and sparkling audio, the new Twin Power Supply means the SU-GX70 delivers a high signal-to-noise ratio for superbly detailed sound, while the Clean Power Clock Generator technology taken from Technics’ Reference Class components enables high-precision digital signal processing for supreme audio accuracy.
Streaming Services
For a truly flexible music listening experience, the SU-GX70 is designed around the Chromecast platform for Spotify, TIDAL, Deezer, Qobuz, and Amazon Music HD integration, with support for MQA hi-res audio streaming services built in. It will also be Roon ready (via OTA update) in the near future.
Wireless Connectivity
Wi-Fi, AirPlay 2, Chromecast and Bluetooth connectivity allow for seamless wireless network communication, while FM, DAB+, and Internet radio support means you can tune into your favourite shows, hassle-free.
Wired connectivity
Physical connectivity options include two line inputs, three digital inputs, USB-A, USB-B and HDMI (ARC). And – as to be expected from a company at the forefront of turntable
performance – a high-grade low-noise phono EQ allows you to hook up a record player
with a moving magnet pickup cartridge for a sublime audiophile performance with all
the authentic warmth of vinyl.
Built to look beautiful in any home, the SU-GX70 comes in an elegant, minimalist design in both silver and black finishes.
