Luxman L-550AXII Integrated Amplifier 
 
L-550AXII is a Mark 2 model of L-550AX which launched in 2011. L-550AXII makes its debut featuring a high-precision electric controlled attenuator LECUA and the latest version of proprietary high sound quality feedback circuit ODNF4.0, both are used in LUXMAN’s upper range amplifiers.
 
Keeping the symbolic appearance with traditional pointer-type meters on the front panel, the essence of the expressive power that made a huge step forward whilst developing the flagship integrated amplifier L-590AXII was poured into this model to provide its dense expression particular to pure A class sound and more detailed reproduction of the low range.
