Description from the seller
Technics SU-V550 Class AA Stereo Integrated Amplifier – Made in Japan
If you’re looking for a genuine 1980s Japanese powerhouse to serve as the heart of your hi-fi stack, the Technics SU-V550 is one of the finest choices in its class. Weighing in at nearly 8 kg and equipped with Technics’ signature Class AA circuitry, this integrated stereo amplifier drives your speakers with remarkable dynamics, a crystal-clear, warm soundstage, and effortless power reserves often missing from modern entry- and mid-level amplifiers.
Why Choose This Amplifier?
• Class AA Amplification Technology: Technics’ renowned circuit separates voltage amplification from current drive, reducing distortion to a virtually unmeasurable 0.002% while keeping the sound detailed and fatigue-free.
• Generous Power Reserves: The robust power supply delivers a continuous 65 watts per channel into 8 ohms (and 105 watts into 4 ohms), allowing it to easily control larger floorstanding speakers with tight, authoritative bass.
• Premium Phono Stage (MM/MC): Supports not only standard Moving Magnet (MM) cartridges, but also high-end Moving Coil (MC) turntables without needing an external phono preamp—a rare feature in this category.
• CD Direct Function: Bypasses the tone control circuits at the push of a button, ensuring the signal from your CD player or modern DAC takes the shortest, purest path to the power amp stage.
• Dual Speaker Switching (A / B): Drive two pairs of speakers independently or simultaneously, making it easy to fill two separate rooms with sound.
Technical Specifications:
• Type: Stereo Integrated Amplifier (Class AA)
• Year of Manufacture: 1988–1989 (Made in Japan)
• Continuous Power Output: 2 × 65 W (8 Ω) / 2 × 105 W (4 Ω)
• Total Harmonic Distortion (THD): 0.002% (8 Ω, 20 Hz – 20 kHz)
• Frequency Response: 20 Hz – 20 kHz (full band) / 3 Hz – 100 kHz (-3 dB)
• Damping Factor: 60 (8 Ω) / 30 (4 Ω)
• Signal-to-Noise Ratio: 91 dB (Line/CD), 77 dB (Phono MM), 64 dB (Phono MC)
• Inputs: Phono (switchable MM/MC), Tuner, CD, AV/AUX, Tape 1/DAT, Tape 2
• Speaker Load Impedance: 4 – 16 Ω
• Features: CD Direct switch, Subsonic filter (20 Hz), Loudness, Rec Selector, Headphone jack
• Dimensions (W × H × D): 430 × 126 × 311 mm
• Weight: 7.9 kg
