Integrated amplifiers
Technics SU-G700M2
The model received an improved high-speed PSU with a low noise level and the same field-effect transistors based on gallium nitride (GaN) and silicon carbide diodes as the SU-R1000. The pulse switching frequency was slightly increased from the usual 100 kHz to 400 kHz, which made it possible to stabilize the supply of voltage and current, as well as reduce the effect of modulation noise on sound quality.
Integrated amplifiers
Technics SU-R1000
The Class D power amplifiers in the Technics SU-R1000 are made using proprietary JENO Engine technology, which ensures that there is no digital distortion of the signal and makes the sound transparent and balanced. An additional advantage of the circuit is the use of its own PWM converter, which provides a wide dynamic range.
Integrated amplifiers
Technics SU-R1000
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.
