Luxman SQ-N150 Vacuum Tube Amplifier

The Luxman SQ-N150 is the latest heir to Luxman’s proud tradition, which is delivering music reproduction of exceptional warmth and clarity.

Meticulous vacuum tube engineering – Luxman SQ-N150 Vacuum Tube Amplifier

You’ll enjoy surpassingly detailed, open music reproduction thanks to the exceptional linearity of LUXMAN’s P-K split-phase inversion circuit. We married an input stage of two JJ Electronic ECC83 miniature double triodes to a push-pull output with four JJ Electronic EL84 pentodes. And with our deep knowledge of tube design, we configured the SQ-N150 for consistent performance and long operating life. On paper, we rate power output at 10 Watts + 10 Watts at 6 ohms. In practice, the sound is fit for the most demanding listeners.

Versatile preamplifier available in the Luxman SQ-N150 Vacuum Tube Amplifier

LUXMAN provides three line inputs and a phono section that accommodates both moving magnet and moving coil cartridges, so you don’t need to purchase a separate MC preamp. We plated the RCA jacks in gold and pitched them at 18 mm to accommodate high-end cables. For minimum crosstalk between left and right channels, we used the same input selector IC as on our top-of-the-line C-900u control amplifier. For ultimate sonic purity, the Line Straight mode can bypass the Bass, Treble, and Balance controls. The headphone output jack is ideal for late-night listening.

Remote control available in the Luxman SQ-N150 Vacuum Tube Amplifier

The aluminium-finished remote control operates volume as well as a LUXMAN CD player, such as the matching LUXMAN D-N150 digital player.

Elegant and compact design

The 5 mm thick aluminium chassis has a modest “A4” footprint, just 210 x 297 mm (8-1/4 x 11-3/4 inches), not including projecting parts. The blasted white finish contrasts nicely with the hairlines on the machined aluminium controls. The orange LED lighting of the analogue level meters provides a visual counterpoint to the glow of the vacuum tubes.
