Technics SU-R1000 is a fully digital device. Signals from analog inputs are digitized, all their processing occurs in digital form. The output stages operate in class D, and all power supplies are pulsed. As we know, audiophiles do not respect such solutions too much, preferring time-tested class A/AB amplifiers. Well, the company set an ambitious task - to create a fully digital amplifier (without introducing hybrid circuits for current and voltage into the circuit design, like, say, Devialet Expert 220 Pro, which we recently reviewed), breaking all traditional canons on the topic of how such a device should sound.

Technics SU-GX70 部分得益于新的配对电源。此外，借鉴自高端 Technics 组件的 Clean Power Clock Generator 技术，承诺提供高精度数字信号处理和“高音质”。

Technics SU-R1000 中的 Class D 功率放大器采用专有的 JENO Engine 技术制造，确保信号没有数字失真，使声音透明且平衡。电路的另一个优点是使用了自己的 PWM 转换器，提供了宽广的动态范围。

该型号配备了改进的高速电源，具有低噪声水平，并使用与SU-R1000相同的基于氮化镓（GaN）和碳化硅二极管的场效应晶体管。脉冲开关频率从通常的100 kHz略微提高至400 kHz，这使得电压和电流的供应得以稳定，并减少了调制噪声对音质的影响。
