Technics presented SU-R1000, the first integrated amplifier of the Reference Class range that includes the SE-R1 stereo power amplifier, introduced on the market in 2014. The product, announced at IFA 2020, features a digital amplification section capable of deliver a power of 150 W x 2 channels into 8 ohms (300 W into 4 ohms).
SU-R1000 takes up part of the technologies used on the SE-R1 power amp and combines them with other new solutions. First of all, the switching power supply circuit was improved, a modification that allowed to increase the signal / noise ratio. Further adjustments have also been made on the power section.
Four independent units separately supply power to the digital and analog circuits of the pre-amp stage as well as the left and right channels of the amp stage. This prevents interference and improves performance. The use of a gallium nitride (GaN) driver then made it possible to shorten the signal path and increase linearity.
Another novelty is ADCT (Active Distortion Canceling Technology), the Active Distortion Canceling Technology of the final stage. ADCT analyzes the difference between the speaker output and the signal output on the JENO circuit in order to apply the appropriate correction to the digital amplification system.

The SU-R1000 also sports a new Pre-Phono with some special features. Techcnics defines it as "intelligent" as it is capable of ensuring precise equalization (thanks to algorithms and a dedicated DSP) and performing automatic adjustments using the supplied Calibration Disc. The aforementioned vinyl allows to measure the performance of the head and to make some targeted corrections (for example the cancellation of the crosstalk).
The JENO (Jitter Elimination and Noise-Shaping Optimization) and LAPC (Load Adaptive Phase Calibration) technologies are taken from the SE-R1 power amp. The first eliminates the so-called jitter, a phenomenon that can cause distortion following a misalignment and which results in a loss of quality. LAPC, on the other hand, optimizes the management of loudspeakers by measuring the performance of the amplifier with the speakers connected, in order to obtain a more linear response.
Available connections include a Phono XLR input and two USB-B ports for using the SU-R1000 as a DAC (digital-to-analog converter). Tracks in MQA, PCM up to 384 kHz / 32-bit and DSD formats are outdated. Availability is expected by the end of the year in black or silver. The price is indicatively set at 7,000 euros.
