LUXMAN introduces the PD-191A, a premium turntable system designed to replace the long running PD-171 series.
Savor the endlessly rich warmth of a piece of music and that special sense of time flowing differently when you play a cherished analog recording. PD-191A is a superb player capable of delivering the excellence of vinyl recordings playback experiences. Our newly developed, original tonearm, with extremely high initial sensitivity, uses a knife-edge vertical bearing system to realize those sensitive movements that make up the finest nuances of a musical moment. Combining a silent and refined DC motor belt-drive system supported by a robust power supply; PD-191A offers a truly high-fidelity and emotional vinyl listening experience.
Newly Developed, Completely Original Tonearm
Specially developed for the PD-191A is our LTA-710 static balanced tonearm which employs knife-edge bearing technology for excellent initial movement sensitivity. A joint development with the audio brand SAEC, who have been designing tonearms for more than 40 years, the LTA-710 brings many highly regarded technologies to the LUXMAN turntable family. A fully-fledged original arm design that required two and half years to develop. By setting the effective arm length to 10 inches, tracking errors are further suppressed and resistance to vinyl surface vibration effects is enhanced. Even the gentlest of musical signals picked up by the phono cartridge from the grooves on the record are reproduced faithfully. In addition, the LTA-710 supports detailed settings such as stylus pressure, anti-skating, height adjustment according to the cartridge to be installed, etc., which is possible only because the tone arm is assembled with high mechanical precision to thoroughly maintain playback fidelity.
The drive motor is one fundamental component of a belt-drive analog player where powerful and stable platter rotation is of paramount importance. The PD-191A features an original, high-precision, high-torque, brushless DC motor supported by a float-mounted, highly stable and fully regulated large-capacity power transformer that has been upgraded to higher specifications for today’s favored high-mass platters. Our sine wave PWM/PID rotation speed control* programming achieves constant and accurate rotation control under various demands and a high-performance reference clock for speed correction, using a MEMS oscillator with excellent temperature characteristics, is deployed. As a result, precise speeds and quiet platter drive are assured.
*PID rotation speed control: “Proportional: Proportional operation” fast adaptation to the target rotation speed, “Integral: Integral operation” Control system to correct minute errors, “Differential: Differential operation” rapid auto adjusting for speed fluctuations. The PD-191A programming system fully integrates these controls with the drive motor unit.
A heavyweight, high-mass platter with a huge moment of inertia
The platter chosen for the PD-191A is a 35mm-thick, 5.2kg heavyweight disk, machined from a single, extremely thick aluminum billet, precisely diamond cut and finished to exact surfaces which beautifully reflect light. The platter acts as a flywheel with a huge moment of inertia of 0.7t·cm2 , delivering smooth and confident rotation. The spindle supporting the platter boasts high-rigidity specifications with its high-tensile strength stainless steel shaft (diameter 16mm) and a customized bearing support system. This structure combines a PEEK* thrust bearing, with its excellent heat resistance and wear resilience to a matched brass radial bearing filled with organic molybdenum oil that maintains stable lubrication even under high loads while firmly supporting the platter. The motor’s energy is transferred to the platter via an EPDM* drive belt that is resistant to aging and accurately supports the high-torque brushless DC motor output without loss.
Our selection and finishing of the external and structural materials that make up the finished product are highly important to us as we feel that the listener’s operation of an analog player should be a tactile and visually satisfying experience. A feast for the eyes, the PD-191A is elegant and sophisticated, with a rosewood-stained, solid natural wood front panel with a beautiful glossy finish, contrasting with the finely hairline-treated aluminum top panel. In addition, by offsetting the mounting of the motor inside the lower chassis, we realized a stylish, low center of gravity form with a total height 12mm lower than the earlier PD-171A. In addition, by focusing on the operational systems, such as power supply, turntable start/stop, rotation speed switching and adjustment on the top panel, we have pursued utilitarian and functional beauty. Sold separately is an available and highly recommended purpose-built 4mm thick acrylic dust cover equipped with cam/spring supporting hinges for easy opening and smooth closure.
Multiple Integrated Vibration Damping Structures
The underslung suspension structure, in which the main components are attached to a 15mm thick aluminum plate, has succeeded in achieving both high rigidity and damping performance. Also, by mounting the motor drive system and power transformer on an extra thick bottom plate, insulated with damping rubber, delicate signal pickup is protected from external vibrations, greatly improving the mechanical S/N ratio ( rumble ) and feedback resistance.
Three selectable rotation speeds with pitch control and stroboscope indicator
The PD-191A supports 3 rotation speeds, 33 1/3, 45 and 78 RPM. To visualize the rotation speed, we have adopted a reflected LED stroboscope, which was well received with the earlier PD-171 series. The new strobe reflecting strip pattern has enhanced visibility and, by utilizing a dedicated control for each individual rotation speed, more reliable and precise rotation speed adjustments are possible.
Original Anti-Vibration Design
In order to maintain horizontal alignment, the PD-191A incorporates special damping rubber with excellent temperature characteristics and resistance to long-term deterioration into our originally designed, large-diameter insulator legs that can each be level adjusted up to 5 mm in height to prevent the transmission of feedback and external vibrations.
Headshell & Phono cable
Our original lightweight aluminum headshell bearing the LUXMAN logo has unique specifications and features D.U.C.C. conductors for the lead wires. An aluminum EP adapter and a standard 5Pin ( DIN type ) to RCA phono cable using audio grade OFC wire are also included. Aftermarket cable replacement upgrades are possible.
Abundant Options for Tonearm Mounting
By making the arm base independent, it is easy to install various tonearms ( 9 to 10" ) from different manufacturers ( separately sold tone arm bases are common for the PD-171A/AL ). At the rear of the main unit, an external arm base that supports a 12" tonearm ( initially designed for the SME 3012 ) is also available ( sold separately ) to expand your enjoyment of vinyl record playback.
