Luxman Luxman - C-12 and M-12 Hi-fi set - Multiple models

Here is an iconic vintage pairing from the prestigious Japanese brand Luxman: the control preamplifier C-12 and the stereo power amplifier M-12.
Produced in 1978, these units represent the excellence of the "Laboratory Reference / Studio Standard" series. They are sought after by collectors for their DC (Direct Coupled) construction, an advanced technology that removes capacitors from the signal path, ensuring exceptional sound purity and incredibly controlled bass.

The set includes:
1. Luxman C-12 (DC Stereo Preamplifier)
A preamplifier with a minimalist and elegant design, built for maximum fidelity.
• Linear Equalizer: Unlike traditional tone controls, the C-12 uses an exclusive "Up Tilt / Down Tilt" system. This allows rotating the entire frequency curve, offering tonal corrections that are much more natural and musical than classic bass/treble controls.
• Phono Stage: Equipped with high-quality turntable inputs.
• Circuits: Clean internal layout to minimize interference.
• Serial Number: 902237

2. Luxman M-12 (DC Stereo Power Amplifier)
A powerful and compact amplifier, famous for its musicality.
• Power: Delivers 80 Watts per channel into 8 Ohms with virtually nonexistent harmonic distortion (0.006%).
• Design: Features the characteristic honeycomb grille that ensures excellent heat dissipation.
• Sound: Typical Luxman timbre: warm, detailed, yet fast and dynamic.
• Serial Number: B9101394

• Operation: The units power on normally (the amplifier’s internal indicators are visible).
• Aesthetics: Please inspect the photos carefully. The brushed aluminum front panels are in good vintage condition. However, the top metal covers (the chassis) of both units are somewhat worn, as shown in the images. The original brown paint is damaged in several areas. This is purely an aesthetic defect due to age and does not affect the internal mechanics.

• Originality: Power cords and components are original.
