SU-GX70

The Technics SU-GX70 is a network audio amplifier made by Technics, with HDMI ARC, optical and coaxial digital inputs, PHONO (MM)/LINE analogue inputs, USB, Bluetooth, AirPlay 2, Chromecast built-in, Spotify Connect, and Internet radio. It uses a fully digital amplifier with a JENO Engine, LAPC speaker-impedance adaptive correction, a dedicated power supply for the power-amplifier circuits, and a roughly 130 kHz high-speed switching power supply. Its analogue section uses discrete amplifier circuits with low-noise FETs, thin-film resistors, film capacitors, and electrolytic capacitors, while the enclosure has a 7 mm hairline-finished aluminium front panel and a solid-aluminium volume knob.
