Product Details
Technics SU-R1000 Reference Class Integrated Amplifier at Vinyl Sound Toronto, Canada
The Technics SU-R1000 is the Reference Class stereo integrated amplifier from Technics (Osaka, Japan), available at Vinyl Sound in Toronto, Canada. Delivering 150 watts per channel into 8 ohms and 300 watts per channel into 4 ohms, the SU-R1000 is a digital amplifier of exceptional sophistication, combining the JENO Engine jitter elimination system, Load Adaptive Phase Calibration, Active Distortion Cancelling Technology, an Advanced Speed Silent Power Supply with four independent power supply units, and an Intelligent Phono EQ with a bundled Calibration Record for cartridge-specific crosstalk and frequency response correction. For vinyl listeners and digital audiophiles who want a single reference-grade component at the centre of a system, the SU-R1000 is one of the most technically complete integrated amplifiers available at any price.
Four Independent Power Supply Units
The SU-R1000 uses four completely independent power supply units: one for the analogue preamplifier circuits, one for the digital preamplifier circuits, and separate units for the left and right channel power amplifier stages. The Advanced Speed Silent Power Supply fixes the switching frequency in the 400 kHz band, eliminating the modulation noise caused by variable-frequency switching in conventional switching supplies, and adds a Super Low Noise Regulator in the output stage to prevent high-frequency noise contamination. This architecture prevents power-line-induced interference between circuit blocks and achieves a high signal-to-noise ratio with exceptional channel separation throughout.
Frequently Asked Questions
Q: What is the Technics SU-R1000?
A: The Technics SU-R1000 is a Reference Class stereo integrated amplifier delivering 150 watts per channel into 8 ohms and 300 watts per channel into 4 ohms. It features the JENO Engine jitter elimination system, Load Adaptive Phase Calibration, Active Distortion Cancelling Technology, four independent power supply units with Advanced Speed Silent Power Supply, an Intelligent Phono EQ with Crosstalk Canceller and PHONO Response Optimiser, and USB audio support up to DSD 22.4 MHz and PCM 384 kHz.
Q: What is Load Adaptive Phase Calibration (LAPC) and why does it matter?
A: LAPC measures the actual impedance and phase characteristics of the connected loudspeaker and applies real-time correction to the amplifier's output to compensate. Because real loudspeakers present complex, frequency-dependent impedance rather than the flat resistive load used in standard amplifier measurements, LAPC ensures the SU-R1000's output is optimised for the specific speaker in use rather than a theoretical ideal, resulting in tighter bass control, more accurate imaging, and better dynamic performance than an uncorrected amplifier driving the same speakers.
Q: What is the Intelligent Phono EQ on the SU-R1000 and what is the Calibration Record?
A: The Intelligent Phono EQ is a hybrid analogue-digital phono stage that applies RIAA equalisation across both analogue and digital domains for exceptional accuracy. It includes a Crosstalk Canceller that measures the installed cartridge's actual crosstalk characteristics using a test signal on the bundled Calibration Record and corrects them via DSP, and a PHONO Response Optimiser that measures and corrects the cartridge's actual frequency response deviations caused by impedance matching. Each function is individually switchable to suit the user's preference.
Q: Does the Technics SU-R1000 support DSD and high-resolution audio?
A: Yes. The SU-R1000 supports PCM up to 384 kHz / 32-bit and DSD up to 22.4 MHz via its two USB-B inputs in ASIO Native mode. It also accepts standard PCM from its optical and coaxial digital inputs.
Q: Can the SU-R1000 drive difficult or demanding loudspeakers?
A: Yes. With 300 watts per channel into 4 ohms, Active Distortion Cancelling Technology correcting for counter EMF and load-dependent distortion in real time, and Load Adaptive Phase Calibration compensating for the specific speaker's impedance curve, the SU-R1000 drives demanding loudspeakers with greater control and accuracy than most conventional amplifiers of equivalent rated power.
Q: Does the Technics SU-R1000 have a phono input for a turntable?
A: Yes. The SU-R1000 includes both a standard RCA phono input supporting MM and MC cartridges and a dedicated balanced XLR MC phono input with Neutrik connectors, plus the Intelligent Phono EQ with Calibration Record for cartridge-specific correction. It is one of the most capable built-in phono stages in any integrated amplifier currently available.
Q: Where can I buy the Technics SU-R1000 in Toronto or Canada?
A: The Technics SU-R1000 is available at Vinyl Sound in Toronto, Canada, an authorised Technics dealer. Contact us to arrange an audition or to discuss building a complete reference system around the SU-R1000.

JENO Engine and Load Adaptive Phase Calibration
The SU-R1000's core digital amplifier technology is the JENO Engine (Jitter Elimination and Noise-shaping Optimisation), which addresses jitter across the entire frequency range using two complementary systems: a clock generator in a noise-shaping configuration for low-frequency jitter reduction, and a high-precision sample rate converter for high-frequency jitter suppression. The original high-precision PWM conversion circuit then optimises noise-shaping speed, degree, re-quantisation number, and PWM gradation to convert high-resolution signals without damaging dynamic range. Load Adaptive Phase Calibration (LAPC) measures the connected speaker's impedance and phase characteristics and applies correction, so the amplifier's output is optimised for the specific speakers in use rather than an idealised resistive load.
Active Distortion Cancelling Technology
Conventional digital amplifiers are affected by distortion from a speaker's counter electromotive force and by voltage drops in the output stage, distortion that varies with the speaker load and cannot be corrected by a fixed filter. Technics' Active Distortion Cancelling Technology (ADCT) continuously compares the speaker terminal output with the JENO Engine output, extracts the difference as a distortion signal, and applies real-time correction to the digital output. The result is powerful speaker driving authority, 150 W per channel into 8 ohms and 300 W into 4 ohms, combined with the low noise, precise imaging, and wide soundstage of a well-implemented digital amplifier.
Intelligent Phono EQ with Calibration Record
The Intelligent Phono EQ is a hybrid analogue-digital system: a 40 dB analogue low-pass filter suppresses bit loss before A/D conversion, after which high-frequency RIAA equalisation is applied with high precision in the digital domain. The Crosstalk Canceller measures the installed cartridge's actual crosstalk using a test signal on the bundled Calibration Record and applies reverse correction via the built-in DSP, improving stereo image precision and soundstage width. The PHONO Response Optimiser measures the cartridge's actual frequency response using a TSP signal on the same record and corrects impedance-matching-induced deviations. Both MM and MC cartridges are supported, including a dedicated balanced XLR MC input with Neutrik connectors and a full-discrete symmetrical circuit.
