Luxman L-509Z Integrated Amplifier
The Z generation of integrated amplifiers reaches a new peak The new generation Z series flagship L-509Z has evolved into a presence that transcends the concept of integrated amplifiers. Both the preamplifier and power amplifier circuits simultaneously use the new generation amplification feedback engine "LIFES" for the first time. The volume control part is equipped with a new mechanism "LECUA-EX" that suppresses sound quality deterioration and realizes a precise operational feeling. The "one-body separate" concept, which aims to be the ultimate all-in-one amplifier, has reached unprecedented heights. The L-509Z is born, a new pinnacle of integrated amplifiers that pursues the ideal of audio by incorporating a passion for music into its technology.
The L-509Z combines a high-precision rotary encoder with a newly developed weight rotation mechanism to complete the "LECUA-EX" that achieves even greater reliability and a natural, high-quality feel. With 88 fine steps from 0 to 87 dB, the speed at which the volume knob is turned, and the setting that accelerates the volume increase/decrease by pressing and holding the remote control, you can adjust the volume comfortably and thoroughly with no deterioration in sound quality.
The power supply section requires instantaneous current supply and high voltage stability. The L-509Z is equipped with Luxman's traditional high-inertia power supply circuit with a 600VA EI-type custom transformer that boasts high regulation and newly developed large-capacity block capacitors (10,000μF x 8).
