Kenwood KD-770D with automatic tonearm lift/shut-off and quartz-controlled direct drive
Solid wood plinth with a satin-finish lacquer coating
The Kenwood KD-770D (known in Japan as the KP-770D) is a high-end, quartz-controlled direct-drive turntable designed for audiophiles. Manufactured in Japan between 1984 and 1987, it combines excellent analog sound performance with a sophisticated aesthetic.
Among HiFi enthusiasts, the Kenwood KD-770D is regarded as an exceptionally durable, smooth-running, and sonically superior turntable. Its detachable headshell (featuring either a standard SME-type mount or a proprietary Kenwood system) allows for great flexibility when choosing and installing different phono cartridges.
Ortofon OM5E Phono Cartridge: The Ortofon OM5E is a high-quality cartridge, noted for its lively character and neutral sound profile. It is equipped with an elliptical stylus, ensuring balanced, distortion-free playback.
Turntable Feet: Stainless steel, height-adjustable; total weight 2520g, diameter 65mm, total height 28mm.
Record Stabilizer (Weight): This weight ensures that the vinyl record sits flat on the platter and rotates steadily. Falling into the medium-weight category, it applies just enough pressure to dampen record vibrations without placing excessive strain on the platter bearings. Using this stabilizer will enhance the sonic performance of your audio system.
Key Features & Construction
Drive and Motor: The turntable utilizes Kenwood’s rigid DL motor—a coreless, slotless DC servo motor. It is governed by a high-precision quartz-locked PLL (Phase-Locked Loop) control circuit, ensuring exceptionally low wow and flutter and perfect rotational stability.
Operation (Semi-automatic): While primarily designed for purist, manual operation, the KD-770D includes a convenient, gentle auto-lift function. At the end of a record, a non-contact optical sensor triggers the tonearm to lift—completely silently—and the motor switches off.
Tonearm: The unit features a statically balanced, straight "High-Stability" (HS) tonearm constructed from a rigid tube. Its robust, trapezoidal bearing assembly is engineered to effectively isolate the cartridge from unwanted resonances and vibrations.
Chassis & Enclosure: The substantial chassis weighs in at an impressive 11.7 kg. A high-gloss, deep-black piano lacquer finish gives the turntable a sophisticated, timeless aesthetic. The heavy, die-cast aluminum platter weighs nearly 2 kg, providing significant inertia (flywheel effect).
