Luxman CL-1000 Control Amplifier

Luxman CL‑1000 – Flagship Vacuum Tube Control Amplifier

The Luxman CL-1000 stands as the pinnacle of Luxman’s control amplifier line—an exquisite fusion of time-honored craftsmanship and cutting-edge audio engineering. From its rich wooden veneer to its meticulous internal construction, it’s a showcase of musical refinement.

Signature Sound & Sophisticated Engineering

LECUTA Transformer Attenuator
Utilizes a 34-step rotary switch that activates relays outside the signal path to select from transformer taps—delivering precise, distortion-free volume control, even at ultra-low levels. 

Nanocrystal-FineMet & Super Permalloy Transformers
Crafted with advanced core materials (FineMet for the attenuator, Permalloy for input/output), these transformers offer exceptional clarity, elevated channel separation, and minimal signal loss. 

E88CC Dual Triode Vacuum Tubes & Oil-Impregnated Capacitors
Two-stage amplification powered by high-reliability JJ E88CC tubes and Luxman’s proprietary capacitors delivers rich dynamics, low noise, and natural tube warmth. 

Demagnetizer with Articulator Function
Automatically demagnetizes transformer cores on startup to preserve sonic purity. A manual “Articulator” switch offers additional control. 

Resonance-Damping Construction
Features a three-layer anti-resonant front panel, walnut and rosewood cabinet, cast-iron isolation feet, and internally damped chassis design to minimize vibration and ensure pristine sound. 

Extensive Connectivity & Control

Phono Stage for MM/MC Cartridges
Includes MM and MC support with rear-mounted six-position impedance/capacitance switches for tailored vinyl playback. 

Tone and Output Controls
Features independent bass/treble tone controls (±8 dB with selectable turnover frequencies), a low-cut filter (30 Hz), balance knob, mono switch, phase-invert, and “Line Straight” bypass for purist operation.
