The L-509Z is a new model and "range topping flagship" of our latest Z-series

integrated amplifiers. This "single-chassis separates" concept with high-end sound

challenges the performance of stand-alone pre-amps and power amps, having

undergone an astonishing evolution from earlier L-509 models. At the heart of the

amplifier is our newly developed "LIFES" amplification feedback engine and it is the

first to be equipped with a discrete circuit configuration for each of the pre and power

sections, bringing an overwhelming power of expression to bear for the new

generation. In terms of functionality, it is equipped with a 7-segment LED volume level

display, a built-in phono amplifier with a 3-stage gain switching circuit and an

additional MIDDLE tone that is useful for adjusting the vocal range. The substantial

chassis incorporates many design features from our ultimate M-10X power amplifier

including the thick alloy top panel with hairline finish and ventilation ports.
