Japan-Made Luxman P-750u Headphone Amplifier Features Fully Balanced Circuit and Short-As-Possible Signal Paths: Exceptional in Its Single-Minded Goal to Make Your 'Phones Soar
Luxman's goal for the P-750u headphone amplifier was to be better than the best – and to design a new flagship. Built around a fully balanced circuit with enlarged traces and short-as-possible signal paths, this three-step-sensitivity amplifier is optimized to mate with reference headphones. And with no DAC in sight, the 30-pound Japanese unit remains exceptional in its single-mindedness: To make your ‘phones come to life like you have never before experienced. Equipped with Luxman's ODNF Version 4.0 feedback circuit for improved high-frequency characteristics and lowered output impedance and stellar LECUA computerized attenuator for stunningly sharp accuracy, P-750u meets the company's goals and more. 100% Music Direct Guaranteed.
Audiophile-Grade Output Connections and Power Supply
P-750u features a choice of headphone outputs including a standard stereo jack (unbalanced) output terminal, a stereo pair of balanced 3-pin XLR terminals, and a 4-pin XLR balanced terminal for compatibility with high-end headphones. P-750u is enhanced further with the inclusion of a highly stable power-supply circuit consisting of a highly regulated OI-core power transformer, two 10,000 µF custom block capacitors in the power amplifier stage, and two 3,300µF custom block capacitors in the pre-driver stage for immense power and stability.
Control Integrated with Luxman's Inimitable LECUA Volume Control
In addition to three-step sensitivity selection, allowing the output sensitivity to be chosen according to various headphones, P-750u features a left-right balance adjustment control. Both functions are controlled by LECUA, a high-quality computerized attenuator to minimize the deterioration of sound quality over the volume control range.
Beeline Construction for Shortest Signal Route
To realize smooth, stress-free signal trans mission, Luxman's original Beeline construction allows the wiring and signal transmission to take the shortest optimal route (like the homing route of a bee). A non-angled wiring pattern with straight and smoothly curved traces on the circuit board also contribute to the smooth passage of audio signals.
Refined Chassis and Cast-Iron Legs
The dual design of the base chassis, constructed from 3mm sheet steel, maximizes rigidity and lowers the center of gravity. A mirrored, rhodium-plated logo plate on the front panel combines with the blaster white metallic cabinet for a truly refined finish. Gradation cast iron legs used on the Luxman 900 Series separate amplifier are customized for P-750u for thorough countermeasures against vibration.
