L-550AII has been organized with the developed tuning technique using state-of-the-art circuits and carefully examined parts, and is the second version of L-550A that features rich sound reproducibility. In the amplification section, ODNF version 2.2A that is a customized version of the original ODNF to the pure class A amplification method with 20W + 20W (8Ω) has been adopted. We have refined sound quality with L-550AII resulting from thoroughly reviewing details such as positive adoption of new parts along with inheriting mellow and densified sound. L-550AII is a basic model of a integrated amplifier with pure class A amplification method, which allows you to absorbedly enjoy music time.
