Luxman L-550AXII, A pure class A design transformed into an MKII model.
Pursuing a sound that appeals to the senses while creating a deep musical impression is the ultimate role of the audio amplifier. With a pure class A design, the Luxman L-550AXII integrated amplifier is a refined version of the L-550AX, which was completely restyled in 2011.
MKII model
The MKII model features enhanced functionality with the latest technologies equivalent to the high-end L-590AXII, such as Version 4.0 of the original amplification feedback circuit ODNF. The new LECUA1000, automated attenuator, and a standard buffer circuit with discrete configuration. Such characteristics result in a model with an expressive power that surpasses its class, offering a soft and dense sound that only pure class A amplification can create.
The Luxman L-550AXII is a mid-range integrated amplifier that enhances its maturity in an attractive, functional design, allowing you to fully enjoy music.
