Luxman CL-1000 Tube Stereo Pre-Amplifier
At LUXMAN, we don't consider a technology advanced unless it advances your ability to delight in music. That principle reaches its highest expression in the CL-1000, our flagship vacuum tube control amplifier. Successor to the classic C-1000 released in 1975, the CL-1000 pairs beautifully with the acclaimed MQ-300 vacuum tube stereo power amplifier. Both reflect LUXMANs singular expertise in vacuum tube audio. In the 1960s, when the audio industry moved en masse into transistor amplifiers, LUXMAN recognized the ineffable beauty of the tube music reproduction. And we've continued to build tube components without interruption. While the CL-1000 salutes the past, it also embodies the best of today with a major step forward in sonic clarity: the transformer-assisted volume control we call LECUTA (Luxman Electronically Controlled Ultimate Transformer Attenuator).
For exceptional analogue reproduction, the CL-1000 accommodates both Moving Magnet and Moving Coil cartridges with an audiophile-grade phono preamplifier. Six-position switches on the rear panel enable you to optimize impedance and capacitance.
No detail was too small for LUXMAN engineers to consider. The RCA input and output terminals consist of an alloy that combines the conductivity of copper with the durability of brass. We also matched the massive, anti-resonant chassis to iron isolator feet. These feature a density gradient that diffuses shelf-borne vibration.
