Technics SU-GX70

Here are what customers ask for most in a Streaming Amplifier;

People frequently ask about the Technics SU-GX70's network connectivity and apps (Google Home and Technics Audio Center) for setup and control, its sound characteristics (neutral, detailed, punchy), features like LAPC and Space Tune, connectivity options (HDMI ARC, digital and analog inputs), and its performance for music and movies. Users also inquire about its physical design, power output, and overall value as a feature-rich network-integrated amplifier.

Reviews of this amplifier have been ridiculously positive. A winner.

It falls firmly into the category of “just add speakers” all-in-one systems, although given the fact that it also rocks an HDMI ARC port, you could also add a TV and some speakers and have a complete A/V system

sound characteristics - performance on music and movies

(neutral, detailed, punchy)? Yes!

Technically, here is the background. (for a less technical review, see video below)

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.

The design of the power supply is extremely critical in audio systems containing amplifiers, digital circuits and other such components. To eliminate any adverse effects on the amplifier, the SU-GX70 is equipped with a dedicated power supply for the power amplifier circuits that is independent from all other circuits. As such, the same electrolytic capacitors installed in high-end models have been used in the dedicated amplifier power supply and the power amplifier components.

Further, by using the shortest possible connection between the power supply and the power amplifier, the SU-GX70 ensures low noise and low impedance. Elsewhere, the connections between the speakers and power amplifier use non-magnetic brass screws.

The SU-GX70 uses a high-speed switching power supply of approximately 130 kHz. By increasing the switching frequency, noise interference on the music playback bandwidth is reduced. This enables highly responsive power supply for music signals and powerful speaker drive capability
