Technology and music in harmony

CL-1000 beauty

At LUXMAN, they 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, their 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 LUXMAN’s singular expertise in vacuum tube audio.

In the 1960s, when the audio industry moved en masse into transistor amplifiers, LUXMAN recognised the ineffable beauty of the tube music reproduction.

And they 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 they call LECUTA (Luxman Electronically Controlled Ultimate Transformer Attenuator).

In addition, super permalloy core output transformers contribute to a vivid sound stage.

Covered in natural walnut with a rosewood gloss finish, the cabinet lends a touch of warmth and refinement.

All told, the CL-1000 brings advanced technology and musical refinement together in harmony.

Introducing the LECUTA transformer coupled attenuator

The heart of any preamplifier is the volume control.

If not executed properly, this key circuit element can cause left/right channel imbalances and introduce subtle but tangible distortions at low volume.

For this reason, LUXMAN created their acclaimed LECUA attenuator system.

The front panel volume control is actually a 34-step rotary switch that triggers 34 relays located totally outside the signal path.

The relays activate 34 taps on matching left and right transformers.

It is these taps that adjust the volume in carefully calibrated steps.

Because transformer cores can influence sound quality, Luxman selected FINEMET® core material from Hitachi Metals, Ltd.

This has a unique nanocrystal structure for high saturation flux density, high relative permeability and low core loss.

So you’ll enjoy rich, detailed, uncompromising sound even at low volume.

Classic design

In a design reminiscent of their classic C-1000, the front panel uses the latest precision machining to superpose three thick aluminum layers into one massive, anti-resonant assembly.

The aluminum provides a graceful counterpoint to the cabinet, which we cover in natural walnut with a rosewood gloss finish.

Robust vibration countermeasures

External vibration is the enemy of vacuum tube reproduction.

For this reason, LUXMAN engineers built an extremely rigid box chassis reinforced by internal partitions.

For added protection, brackets which hold circuit boards are isolated from the main chassis by special rubber dampers. The result is supple, nuanced music reproduction.

Alloy terminals and cast iron feet

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.

They also matched the massive, anti-resonant chassis to iron isolator feet.

These feature a density gradient that diffuses shelf-borne vibration.

JJ Electronic E88CC dual triode vacuum tubes

Through countless hours of listening, LUXMAN evaluated the sonic characteristics of every circuit element.

They adopted two-stage P-K NF amplification.

The balanced inputs incorporate super permalloy core transformers.

Next, the attenuator driver amplifier achieves 6 dB of gain thanks to a JJ Electronic E88CC dual triode vacuum tube.

They selected the E88CC for superb reliability, extremely low noise, attractive dynamics and a densely detailed midrange.

After LECUTA volume adjustment, the output stage incorporates a second E88CC and independent left/right super permalloy output transformers.

They couple the stages with their own oil capacitors, which greatly improve audio quality.

And to minimise the potential degradation caused by resistors in the signal path, the Line Straight mode completely bypasses the tone controls.

So audio reproduction is energetic, yet effortless.

Vinyl playback with MM/MC phono preamp

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 optimise impedance and capacitance.

Super permalloy input / output transformers

Transformers can have a profound impact on vacuum tube sound quality.

They chose independent left and right output transformers with high-permeability super permalloy cores.

And applied the same grade of transformers to the independent left and right balanced inputs.

The result? Reproduction of outstanding musicality.

Exceptionally stable power supply

When the music reaches a dynamic climax, the power supply must be ready.

That’s why they incorporated a highly stable, extremely potent power supply.

A large power transformer plus independent left- and right-channel filter capacitors provide immediate power.

You get instant dynamic response, excellent left/right separation and high reliability.

Articulator function

Deep experience in signal path transformers has alerted them to a significant downside: residual magnetic fields in the cores.

For this reason, the CL-1000 oscillates and demagnetises the transformer cores every time you turn the power on.

For an even higher degree of sonic purity, you can perform manual demagnetisation using the Articulator switch.

Custom capacitors

Because coupling capacitors influence the sound, they use the LUXMAN oil-impregnated capacitors originally developed for their MQ-300 vacuum tube amplifier.

These help deliver rich, satisfying music reproduction.

In addition, our original low-profile electrolytic capacitors can handle high current despite their small size
