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. Technics SU-R1000 solves the problem gradually - its digital circuitry allows you to implement several unique technologies that radically improve the sound quality.

JENO Engine is a system that will eliminate the traditional "generic" shortcomings of D-class amplification. Jitter is reduced by using a clock generator at low and mid frequencies, as well as a sampling frequency converter in the high frequency range. As a result, jitter is understood throughout the entire bandwidth - and is reduced very significantly.

ADCT (Active Distortion Cancellation Technology) – an active distortion suppression module. An analogue of negative feedback in traditional amplification, only implemented in the digital domain.

LAPC (Load Adaptive Phase Calibration) – a technology for adaptive optimization of loudspeaker impedance, allowing to level out dips in the resistance curve. The unit works in a very interesting way, first calibrating the system using test signals after connecting the speakers, and then, during playback, using the created profile to align the phase and reduce distortion. If you do not like the result, the module can be easily turned off using the remote control.

AS2PS (Advanced Speed Silent Power Supply) – innovative circuitry of power supplies based on gallium nitride (GaN) transistors, characterized by higher operating speed and energy efficiency. All four power supplies (a pair for amplifying the left and right channels and two more for the digital and final analog part of the pre-amplification) are designed according to this scheme and are reliably shielded from interference and noise with steel plates.
