The L-550AX Mark II is the successor to the L-550AX, which launched in 2011. The L-550AX Mark II makes its debut featuring a high-precision, electronically controlled attenuator LECUA and the latest version of our proprietary high quality feedback circuit, ODNF 4.0, both are used in LUXMAN’s top-of-the-range amplifiers. We made huge steps forward whilst developing our flagship integrated amplifier, the L-590AX, and the essence of it’s expressive power was distilled and poured into this model to provide the dense expression characteristics particular to pure class A amplifiers and more detailed reproduction of the low range.
