The realisation of a desirable ideal the ultimate refinement of separates in a single unit.
The NEW L-509X integrates the features of both a high quality separate amplifier and a high performance integrated amplifier into one product. The goal of creating an ideal integrated amplifier, initiated by LUXMAN with the launch of the L-509fSE in 2002, has now been advanced with the development of the L-509X. The L-509X integrated amplifier is equipped with many desirable features, such as the New LECUA1000 and a discretely configured buffer circuit in the output stage of the pre-amplifier circuit. LUXMAN’s ODNF (Only Distortion Negative Feedback) original amplifier feedback circuit and a power supply with independent left and right channel blocking capacitors are intrinsic to this design, as well as many components used only in high end models, ensuring high-quality audio reproduction. The design of the L-509X incorporates the cream of LUXMAN's proprietary technologies, breaking new ground and creating the ultimate expression of “separates in a single unit”.
Chassis structure exemplifies excellence in function and design
The L-509X features a top panel with a beautiful hair-line finish and widened venting to improve heat dissipation. The loop-less chassis structure restricts any increase in ground impedance. Analog level meters, illuminated with white LEDs, add to the elegant and stylish appearance.
Copper alloy terminals
High quality RCA terminals, made of copper alloy, are used for the LINE-1 inputs of the L-509X, combining the beneficial conductivity of copper and durability of brass. The L-509X features many custom-made components befitting a flagship model, such as the robust power supply and high-grade speaker terminals that are compatible with Y-connectors.
High stability power supply
The highly stable power supply circuit developed for the L-509X features a 600 VA EI-core-type power transformer and independent left and right channel large capacity blocking capacitors (10,000μFx4 per channel). This generous custom specification ensures that the power supply unit will not be affected by any load fluctuation.
