A stereo integrated amplifier from Technics with a digital power stage rated at 150W per channel into 8 ohms and 300W per channel into 4 ohms. It has an Intelligent Phono EQ for MM and MC cartridges, balanced XLR inputs and a large dual-needle meter.

Technics builds the SU-R1000 around its JENO Engine and Active Distortion Cancelling Technology. It comes in silver or black.

Why you will love it

JENO Engine and ADCT

Technics says the JENO Engine (Jitter Elimination and Noise-shaping Optimisation) uses a jitter reduction circuit with a clock generator and a high-precision sample rate converter, working with a high-precision PWM conversion circuit.

Active Distortion Cancelling Technology compares the speaker terminal output with the JENO output and corrects the digital signal. Technics says this extracts and removes distortion in the output stage caused by the speaker's counter electromotive force and voltage drops.

Power supply with four independent units

The Advanced Speed Silent Power Supply fixes the switching frequency in the 400kHz band to avoid modulation noise, and a Super Low Noise Regulator follows it. Technics says the result is a high-response supply for the digital amplifier.

Four independent power supply units serve different circuit blocks. The analogue and digital circuits in the pre-amp stage have separate supplies, and so do the left and right power amplifier channels.

Intelligent Phono EQ

The phono stage uses DSP developed from Technics' LAPC work. It has three functions that you can switch on or off: an Accurate EQ Curve, a Crosstalk Canceller and a Response Optimiser.

The Crosstalk Canceller and Response Optimiser measure the installed cartridge using signals on the bundled Calibration Record. Technics says the phono and XLR input sections use completely balanced transmission, and a balanced XLR phono input is provided for MC cartridges.

Exploded view of the Technics SU-R1000 chassis with 6 mm aluminium panels and a 10 mm front panel

Three-section chassis

The inner chassis is a double-deck structure with the power amplifier on the upper deck and the pre-amp on the lower deck. Steel shield plates separate the circuit blocks and reinforce the chassis.

The front panel is 10mm thick, the side and top panels are 6mm alumite-treated aluminium, and the insulators are cast iron. The volume dial and selector knob are machined from solid aluminium.

Digital inputs and A/D conversion

The USB input circuit has a ruby mica capacitor and a power conditioner using nonmagnetic carbon film resistors to block electrical noise from a PC. The A/D converter uses a chip made by Asahi Kasei Microdevices (AKM).

USB audio is USB Audio Class 2.0 in asynchronous mode. It supports PCM up to 384kHz/32-bit and DSD up to 11.2MHz, with 22.4MHz in ASIO Native mode only.

Is it right for you?

A great fit if you…

Want a high-power integrated amplifier with a built-in phono stage for MM and MC
Have balanced sources and want XLR line and phono inputs
Connect a computer, streamer or CD transport by USB, coaxial or optical
Like analogue-style meters on the front panel

Worth knowing

It is large: about 22.8 kg and 459 mm deep
The SU-R1000 has no network streaming. Digital sources connect by USB, coaxial or optical
The phono calibration functions use the bundled Calibration Record. Technics warns a warped record can disturb the measurement and may harm the cartridge
Speaker load impedance is 4 to 16 ohms

Build your system

Vinyl: Use the MM/MC phono input with a turntable
Speakers: Pair with floor-standing or bookshelf speakers
Smaller Technics amp: The Technics SU-G700M2 is the more compact integrated amplifier
