Luxman L-509X Integrated Amplifier

£9,299

The Luxman L-509X integrated amplifier incorporates the highest quality power amplifier and a highest performance pre-amplifier into one unit. The design of the L-509X has the best of LUXMAN's proprietary technologies, breaking new ground and creating the ultimate expression of “separates in a single unit”. 

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

ODNF* Version 4.0 - innovative amplification feedback circuit

An integral part of the design of the L-509X is LUXMAN's original ODNF* amplification feedback circuit, featuring a high-speed primary slew rate, an ultra-wide bandwidth and a low level of distortion that is achieved by feeding back only the distorted components of the audio signal from the output of the amplification circuit. The L-509X is equipped with the latest Version 4.0 ODNF providing a dramatic enhancement of accuracy in distortion detection due to the triple-paralleled first stage error detection circuit. Lower impedance and a higher signal to noise ratio have been achieved due to the paralleled first stage and Darlington equipped second stage amplification circuit. A 3-stage Darlington circuit and a 4-parallel push-pull structure is used for the output stage, similar to the M-700u power amplifier. This achieves output at 120W+120W(8Ω) and 220W+220W(4Ω), enabling the L-509X to drive speakers powerfully with rich dynamics and full expression. *ODNF stands for “Only Distortion Negative Feedback”.

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.

An abundance of user-friendly functions

The L-509X is equipped with a high-quality phono amplifier, compatible with MM and MC cartridges. This model offers all the functions that a high quality integrated amplifier should, including bass and treble tone controls, L/R balance adjustment controlled by LECUA, pre/power separation function, volume control and headphone output, all integrated into a single unit without compromising sound quality.

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.

Discrete buffer circuit

The L-509X is equipped with a discrete buffer circuit that is equivalent to the type used in the high-end LUXMAN C-900u separate amplifier. The clarity of the audio signal is preserved by this circuit whilst at the same time the following power amplification stage's driving force is significantly increased.
