Designed for the Discerning Listener: Luxman L-505uXII Integrated Amplifier Distinguished by Smooth, Detailed Playback and Features MM/MC Phono, Headphone Amp, LECUA Volume Control

Boosted with Luxman's latest ONDF (Only Distortion Negative Feedback) circuitry and proprietary 88-step LECUA volume control, the L-505uXII integrated amplifier marries cutting-edge technology with old-school tradition (back-lit power meters) in a handmade piece designed for the discerning listener. Quieter, smoother, more liquid and detailed than its acclaimed predecessor, L-505uX, this 100Wpc integrated exudes transparency – and comes equipped with both a built-in headphone amplifier and MM/MC phono equalizer, giving you have instant access to private-listening sessions and vinyl. If natural tones, alluring textures, powerful drive, convincing imaging, and preserved nuances are what you seek from music, look no further.

While you'll doubtlessly relish the sound of L-505uXII, you'll also appreciate the future-forward technology invested in the unit that makes such reference-quality performance possible. In addition to the LECUA, L-505uXII boasts a dual-parallel-configured error-detection unit that practically eliminates distortion. A triple-paralleled second amplifier stage includes a Darlington circuit that trams with the ONDF 4.0 to further the dead-quiet playback characteristics. Luxman's "Bee Line" construction emphasizes short signal paths, a high-quality input selector and switching IC enhances separation, and OFC cabling in the internal wiring fosters naturalism.

That's not all. Luxman considered everything in the name of fine sonics. L-505uXII also boasts non-angled circuit-board wiring design for fast signal transmission, dedicated pre out function, pre/power separation option for integration with bi-amped systems, and a large, low-impedance speaker relay for high drivability. LECUA-operated bass and treble tone controls, line-level and balanced inputs, take-notice headphone amplifier, and remote control round out a Japan-built integrated prepared in every way to rock your world. 100% Music Direct Guaranteed.

Improved ODNF Circuit, LECUA Volume Control, Huge Power Supply
Luxman's original ODNF amplification feedback circuit was distinguished by a fast initial slew rate, low distortion, and wide bandwidth – delivering natural, high-fidelity sound. The L-505uXII featuresthe latest ODNF Version 4.0, offering improved high-frequency characteristics and lowered output impedance. A discrete buffer circuit, equivalent to that of Luxman's top-of-the-range C-900u control amplifier, is installed in the output stage of the preamplifier. This discrete design enhances the circuit's ability to effectively drive the power amplifier section while maintaining the purity of delicate musical audio signals. Luxman's Electronically Controlled Attenuator, LECUA, overcomes left/right level deviation and the differing sound quality of each volume point compared to conventional sliding variable resistor volume systems. The highly regulated EI-type power supply features four large-capacity, 10,000μF blocking capacitors that provide powerful speaker drivability, delivering 100Wpc into eight ohms.

  • Loopless chassis structure with independent construction reduces ground impedance generated by chassis current
  • Line inputs and outputs are 18mm RCA terminals to enable connection using high-quality cables fitted with large connectors
  • Left and right speaker terminals configured in-line with identical characteristics for banana plugs and Y-connectors
  • Convenient headphone connection for late-night listening and an AC power inlet for preferred power connection
  • LED-lit level meters and blasted white metallic finish
  • Dedicated aluminum remote control
