The new Luxman L-595A Special Edition is a premium Class A integrated amplifier built to commemorate Luxman’s 95th anniversary. The unique industrial design reimagines the highly regarded L-570 series inaugurated in 1989.
“Not many consumer electronics companies can point to a 95-year heritage,” says Jeff Sigmund, President of Luxman America. “The Luxman L-595ASE validates our ongoing commitment to sonic excellence, superb build quality, and timeless design.”
In place of a conventional serial number, a back-panel plate identifies the amplifier as a 95th Anniversary limited offering and cites the three-digit serial number as “### of 300.” With just 100 units allocated to North America, first deliveries will commence in June at a suggested retail price of US$11,995.
Unlike recent Luxman amplifiers, the new model deletes front panel VU meters. Instead of a rotary input selector, the amplifier features an array of aluminum clad direct selection switchgear, each with an annunciator LED. The Luxman aluminum front panel is accented by a black Alumite lower section, creating an elegant, two-tone scheme reminiscent of the original L-570 series. The calibrated volume control features a bold counterbore and indicator light. Both the front and top panels also feature Luxman’s signature hairline finish.
When Class B transistor amplifiers rose to prominence in the 1960s and ’70s, Luxman engineers were quick to recognize the pitfalls of related switching distortion, says the company. Audiophiles know this distortion occurs when output transistors responsible for one half of a musical waveform switch off and others are switched on to handle the other waveform half. Because this distortion occurs at the “crossover” transition between the top and bottom of all waveforms, Luxman explains, it’s particularly troublesome, becoming more prominent during quiet musical passages. True to its heritage, the L-595A Special Edition eliminates the problem with Pure Class A amplification, available up to its rated power into 8 Ohm loads. During Class A operation, the output transistors operate all the time – no duty cycle switching on and off. The result is music reproduction of stunning textural clarity.
Luxman incorporates the most advanced version of our Only Distortion Negative Feedback (ultimate) – ODNF-u – circuit, with improved error detection.
During operation and with low-level signals, traditional rotary resistive type volume controls often introduce noise. In addition, resistance tracking errors can unintentionally shift the left/right stereo balance with volume adjustments. For these reasons, Luxman has long avoided these types in favour of carefully crafted attenuator circuits. The L-595ASE incorporates the Luxman Electronically Controlled Ultimate Attenuator, LECUA1000, first used in the range topping C-900u control amplifier. This computerized precision attenuator delivers meticulous volume adjustment across 88 steps, while minimizing distortion.
With 30 Watts + 30 Watts RMS, pure Class A into 8 ohm loads and 60 Watts + 60 Watts RMS at 4 Ohms, and stable into 2 Ohms, additional features of the Luxman L-595ASE include three-stage Darlington equipped triple-parallel push-pull configuration; an oversized, highly-regulated power transformer and large, independent left/right filter capacitors of special construction; large speaker relays that minimize resistance for low output impedance and high damping factor; thorough anti-resonant design with a massively overbuilt chassis of 64 pounds (29 kg); density gradient cast iron feet resist shelf-borne vibration; discrete buffer preamplifier output; copper-clad, steel-shielded internal cabling; copper alloy RCA terminals that combine conductivity and durability; Luxman’s peel coat input/output circuit boards eliminates the green film coating that can introduce high-frequency noise; smooth, round-cornered printed circuit board traces optimize signal flow; built-in phono preamplifier with Moving Magnet/Moving Coil cartridge type selection; preamp output/main amp input terminals for bi-amping and SEPARATE function to support home theater installations; electronically controlled bass and treble adjustment; loudness compensation linked to volume-control setting; speakers A + B output terminals with multi-way binding posts; two separate balanced XLR line input pairs; and supplied RA-17A remote control also operates current Luxman digital players.
