Introducing a radical re-design.

Replacing the L-590 and L-507uXII models wasn't easy. They sold in great numbers and have been successful in their class in Europe, Asia and America.

Luxman is looking at the 100th anniversary of its founding in 2025, and has renewed the amplifier circuit topology which has been used in their amplifiers since 1999. With improvements we achieve a more realistic, fresh reproduction - rich in musicality.

A new feedback engine 

Feedback is widely used in amplifiers to reduce distortion, but can have negative side effects. In fact a badly designed amplifier can measure well - using lots of feedback - but sound hard and unlistenable.

Luxman already uses minimum feedback in a topology they call ODNF* 

* ODNF is an abbreviation for Only Distortion Negative Feedback.

How to further improve?

Introducing LIFES

By repeatedly auditioning and rigorously scrutinizing and combining the selected parts, we have achieved the highest performance and quality suitable for use in Luxman's next-generation components. In LIFES Version 1.0, by simply reconstructing the entire circuit, we succeeded in reducing the number of parallel elements while improving performance. The distortion during amplification has been reduced to less than half. The output stage adopts a 3-stage Darlington 3-parallel push-pull configuration, and achieves complete power linearity performance of class AB 110W + 110W (8Ω) and 220W + 220W (4Ω). With a large output comparable to that of a separate power amplifier, it realizes a natural and relaxed sound full of energy, and drives  speaker systems of all characteristics.
