L-550AXII

Pursuing a sound that appeals to the senses whilst creating a deep musical impression is the ultimate role of the audio amplifier. With pure class A design, the L-550AXII integrated amplifier is a refined version of the L-550AX which was itself fully restyled in 2011. The MK II model boasts improved functionality with the latest technologies equivalent to the higher grade L-590AXII such as Version 4.0 of the original amplification feedback circuit ODNF, the new LECUA1000, computerized attenuator, and a buffer circuit with discrete configuration as standard. Such features result in a model with capability of expression above its class, offering a mellow and dense sound that only pure class A amplification can create. The L-550AXII is a mid-range integrated amplifier that increases its maturity in an attractive, functional design for music to be thoroughly enjoyed.
