LUXMAN L-100 CENTENNIAL: A Century of Japanese Audio Heritage

If you like beautifully made Japanese audio equipment, it is difficult to ignore LUXMAN. The company traces the beginning of its business to 1925. This makes LUXMAN one of Japan’s longest-established names in audio.

There is something appealing about this kind of heritage. Not simply because a brand has been around for a long time, but because it has had time to develop its understanding of music reproduction through very different technologies and design philosophies.

LUXMAN has made radios, transformers, phono stages, transistor amplifiers, digital players and, importantly, vacuum-tube amplifiers. Its tube history goes back to the SQ-5A integrated amplifier of 1961. LUXMAN has since then continued developing tube components without interruption. 

The LUXMAN L-100 Centennial was created for its 100th anniversary.  It is a 20-watt-per-channel pure Class A integrated amplifier. On paper, 20 watts may not sound impressive in an era where amplifier power is often measured in hundreds of watts. The L-100 takes a different approach.

The L-100 CENTENNIAL

The central element is LUXMAN’s latest LIFES 1.1 amplification circuit. LIFES is the evolution of LUXMAN’s proprietary feedback technology. In the L-100, LUXMAN uses parallel differential detection in the input stage to further reduce distortion. The output stage is a three-parallel push-pull design and operates in pure Class A.

The power supply is equally important. The L-100 uses a custom EI-core transformer and eight 10,000 μF filter capacitors. This is a substantial power supply for a 20-watt amplifier and helps explain why the amplifier does not behave like a small, low-powered design when connected to demanding loudspeakers.

Volume control is handled by the new LECUA1000, an 88-step electronically controlled attenuator. LUXMAN has connected the attenuator directly to the amplification circuitry in order to keep the signal path short. There is also a discrete buffer circuit derived from the company’s flagship preamplifier designs.

The feature set is generous without turning the amplifier into a complicated piece of equipment. There are MM and MC phono inputs, four line inputs, balanced input, main-in, pre-out, tone controls, loudness, balance and pre/power separation. There are also two headphone outputs, including a 4.4 mm connection with separate left and right channel ground wiring.

The construction follows the same philosophy. LUXMAN uses a loop-less chassis construction, cast-iron insulator feet and specially treated circuit boards. The amplifier weighs 25.4 kg. It is not a lightweight 20-watt integrated amplifier.

Listening to the L-100

We listened to the L-100 with three very different loudspeakers: the Audio Note AN-E, the Spendor 3/1 and the large Spendor Classic 100. This was useful because the 20-watt specification becomes much more interesting when you move away from numbers and listen to what the amplifier actually does.

The first impression is one of insight. The L-100 gives a very clear view into the recording without making the presentation feel analytical. Instruments have a convincing physical presence and voices are rendered with a natural scale. There is a strong sense of the relationship between instruments rather than simply a collection of sounds spread across the stereo image.

Bass was also a surprise. Even with 20 watts, the L-100 had no difficulty producing substantial low-frequency energy. With the Classic 100, we listened to Danse Macabre (Mephisto). The scale of the music was convincing. The presentation was incredible powerful and grand, but it remained ordered. Individual sections of the orchestra occupied their own space and the amplifier maintained control as the music became more complex.

This is perhaps where the L-100 makes its strongest argument. Its 20 watts are not the whole story. The quality of the power supply, the Class A output stage and the way the amplifier controls the loudspeaker all contribute to the impression of authority.

We also used the L-100 with the Audio Note AN-E and Spendor 3/1. Here the amplifier’s ability to resolve voices and instrumental textures became particularly apparent. It does not simply make recordings sound detailed. It gives the listener a better sense of what is happening inside the performance.

With the D-100 CENTENNIAL

The L-100 becomes even more interesting when partnered with the D-100 CENTENNIAL, LUXMAN’s new flagship digital player. The D-100 uses dual-mono ROHM BD34302EKV DACs and LUXMAN’s LIFES 1.1 technology in its analogue output stage.

We listened to Voyage of Youn Sun Nah, with the D-100 feeding the L-100. The recording is an excellent demonstration of what this combination can do with a voice.

The singer’s voice was rendered in a truly emotional fashion, but what stood out most was its palpability. It felt physically present rather than simply positioned between the speakers. Small changes in intensity and phrasing were easy to follow, and the texture of the voice remained convincing without becoming exaggerated.

This is where the combination of the D-100 and L-100 makes sense. The source provides a very high level of information, while the amplifier preserves that information without turning the presentation into a technical exercise. The result is precise, but also human.

A century of experience, without looking backwards

The L-100 CENTENNIAL is clearly connected to LUXMAN’s history, but it does not feel like a nostalgic product. Its pure Class A topology, LIFES 1.1 feedback circuit and LECUA1000 volume control are thoroughly contemporary. At the same time, the amplifier benefits from the accumulated experience of a company that has spent decades working with both tubes and solid-state designs.

That combination is perhaps the most interesting aspect of the L-100. It is a 20-watt amplifier that does not apologise for its modest number. Instead, it concentrates on how those watts are delivered.

For listeners who value natural voices, convincing instrumental textures, control and a strong sense of musical order, the L-100 CENTENNIAL is an integrated amplifier worth serious attention.
