Интегральные усилители — Technics SU-R1000

The SU-R1000 is a Technics two-channel integrated amplifier from the Reference Class range, combining a fully digital power stage with a phono section that accepts both MM and MC cartridges, along with a set of digital inputs for computer and disc sources. In the United States it is listed at USD 11,999.99.

Key specs that matter

Technics rates the SU-R1000 at 150 W per channel into 8 ohm and 300 W per channel into 4 ohm at 1 kHz and 0.5 percent THD, with an FTC rating of 150 W per channel across 20 Hz to 20 kHz. The accepted speaker load runs from 4 to 16 ohm. Line and digital inputs both reach 5 Hz to 80 kHz at minus 3 dB. Analogue sockets include twin RCA line sockets plus one XLR line socket, an RCA phono input for MM or MC, a balanced XLR phono input for MC only, plus main in and rec in, with pre out, rec out and a 6.3 mm headphone jack. Line sensitivity is 200 mV at 22 kohm, MM phono 2.5 mV at 47 kohm and MC phono 300 uV at 100 ohm. The chassis measures 430 x 191 x 459 mm and weighs about 22.8 kg, and power draw is 220 W.

Engineering and use context

The digital side offers two optical, two coaxial and two USB-B inputs, taking PCM up to 384 kHz and 32 bit and DSD up to 22.4 MHz in ASIO native mode. The JENO name refers to jitter elimination with optimised noise shaping - a clock generator in the noise-shaping system reduces low-frequency jitter while a high-precision sample rate converter suppresses jitter higher up. LAPC, the Load Adaptive Phase Calibration system, measures the attached speakers and adjusts the output to suit their impedance behaviour, and ADCT, Active Distortion Cancelling Technology, targets distortion in the speaker drive stage. The phono stage uses a low-noise FET first stage in a differential parallel configuration, with four gain levels to match cartridge output, and its Intelligent Phono EQ adds a crosstalk canceller and a response optimiser. Four independent power supply units separate the analogue and digital circuits and the two channels, inside a rigid double-deck chassis.

Pairing

The balanced XLR phono input suits a low-output MC cartridge on a turntable with balanced wiring, while the two USB-B ports let a pair of computers or a streamer and a laptop stay connected at once. Main in allows the amplifier to serve as a power stage for an external preamplifier or AV processor.
