Luxman's SQ-N150 Integrated Tube Amplifier is built in Japan for superb sound quality. Featuring six valves and classic meters, this amp boasts ECC83 input tubes and 4 EL84 output valves from Slovakia's JJ manufacturing plant. The P-K split phase inversion circuit ensures linearity and power, while Luxman's Oxygen Copper wiring and a 5mm-thick aluminum chassis reduce noise. Connect to 3 gold-plated line inputs or an MM/MC phono section. The signal-to-noise ratio is impressive, and an input selector IC minimizes crosstalk. The Line Direct switch bypasses bass, treble, and balance controls. Listen in private with the included headphone output.
Weighing in at just over 27 pounds, its compact 11.6 x 7.4 x 9.8-inch (WHD) footprint makes it easy to place and admire. In addition to the appealing tonal balance and timbral accuracy produced by its hand-selected internal parts, SQ-N150 is also a stunner on the outside. From the elegant blasted white aluminum casing and smoothly responsive, hairline-finish controls to the warm, orange glow of its LED output meters, SQ-N150 serves as a masterpiece that proves as much fun to look at as it is to hear.
Luxman's P-K Split Phase Inversion circuit provides faithful linearity, allowing you to experience detailed, open music reproduction. It pairs two JJ Electronic ECC83 double triodes with a push-pull output of four JJ Electronic EL84 pentodes, offering 10 Watts + 10 Watts at 6 ohms. A phono section with moving-magnet and moving-coil inputs, gold-plated RCA jacks, and headphones output jack ensure versatile connectivity. Its compact aluminum chassis with hairline controls and orange LED analog level meters make for a sleek design.
