Product Description
The Technics Technics SU-GX70 Integrated Amp is the definitive living room audio center that enables seamless enjoyment of video, audio, and music through next-level integration using Technics’ full digital technologies.
Full Digital Amp, JENO Engine
The SU-GX70 uses a fully digital amplifier that incorporates Technics’ renowned digital audio technology. Its digital transmission system processes signals fully digitally in all stages from input to output. Compared to analogue transmission, this system is less susceptible to signal degradation caused by external noise, ensuring more precise signal transmission. Accurate signal processing not only delivers high-resolution digital audio but also maintains the soft texture inherent in analogue recordings.
Further, a JENO Engine has been used in the HDMI ARC (Audio Return Channel), which has been installed in a Technics product for the first time. This helps to reduce any degradation in sound quality caused by jitter during the transmission of digital audio signals (S/PDIF), ensuring unparalleled levels of clarity in TV audio.
High-quality audio components have been used in various other locations, too. For example, chip film capacitors have been used in place of power supply noise-reduction capacitors and signal path coupling capacitors.

The SU-GX70 is a classy-looking unit with a high quality build and finish. In fact, it doesn’t look too dissimilar from the SL-G700M2 streamer-and-CD-player we recently reviewed, with the same dimensions, neatly machined buttons and clear, informative display.
