LUXMAN L-507uXII Integrated Amplifier
Cutting-edge technology comes together with old-school tradition in the highly desirable Luxman L-507uXII integrated amplifier, a handmade component designed for serious audiophiles and music connoisseurs. Enhanced with Luxman's latest ONDF (Only Distortion Negative Feedback) circuitry, a discrete buffer circuit taken from the flagship C-900u, and proprietary 88-step LECUA volume control, L-507uXII distinguishes itself with smooth, quiet, natural, detailed, and liquid playback of everything from discs to vinyl LPs. Rated at 220Wpc into four ohms, L-507uXII 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-507uXII, you'll also appreciate the future-forward technology invested in the unit that makes such reference-quality performance possible. In addition to the LECUA and advanced buffer circuit, L-507uXII 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.
Indeed, Luxman considered everything in the name of fine sonics. L-507uXII 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.
Enhanced ODNF Circuit, LECUA Volume Control, Massive 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-507uXII features the 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 110Wpc into eight ohms.
