I was fresh off reviewing the Rotel S14 Streaming Amplifier. So, I pretty much knew what to expect. But as soon as I unboxed the Technics, I immediately knew that this was a step up. And that it might be a keeper.
The Technics SU-GX70 is a streaming amplifier that is said to retain the ‘sonic genes’ of Technics Grand Class components. It’s a fully loaded amplifier that includes connections for not just traditional audio sources, but video-based ones in the form of HDMI ARC as well.
This features:
I don’t pretend to know what all of what I just read is. And I’m not going to attempt to explain it here. You can read about it on the Technics website where they do a much better job of explaining it.
Needless to say, it’s a fully digital amplifier.
It’s a digital transmission system that processes signals fully digitally in all stages from input to output.
Compared to analog transmission, this system is less susceptible to signal degradation caused by external noise, ensuring more precise signal transmission.
This JENO Engine has also been used in the HDMI ARC input, a first in a Technics product. 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.
Got it? Cool. Me too, I think.
There’s more of course. There’s:
This is 40W into 8 Ohms and 80 into 4.
Frequency response is:
For inputs you get 2 analog, 1 moving magnet phono, 2 Optical, 1 Coaxial, 1 USB A, 1 USB B, Preouts, HDMI ARC, 1/4″ Headphone Output, and Ethernet
I should note that the Techinics team has enabled the HDMI ARC in this amp to somehow mitigate the video signal preventing any unwanted noise or distortion in the audio.
You also get Wi-Fi, Chromecast, Airplay 2, Tidal, Deezer, Qobuz, Spotify, Amazon, Bluetooth, an FM Tuner, and MQA Decoder.
And lest I forget tone controls!
That’s a lot of stuff packed in here. And therefore, it makes sense that it retails at $1999.95 USD.
