LUXMAN SQ-N150

In the 1960s, when the audio industry embraced transistor amplifiers en masse, LUXMAN stood apart with its different approach. The company quickly recognized the ineffable beauty of tube sound and has continued uninterrupted in the production of tube components ever since. Part of LUXMAN’s NeoClassico II series, the SQ-N150 is the latest heir to this noble tradition, offering exceptionally warm and clear music reproduction.

Thanks to the incredible linearity of LUXMAN’s P-K split phase inversion circuit, the SQ-N150 delivers incredibly detailed and open music reproduction. The circuit design features an input stage with two JJ Electronic ECC83 miniature double triodes, paired with a push-pull output stage using four JJ Electronic EL84 pentode tubes. With LUXMAN’s deep knowledge of tube design, the SQ-N150 has been configured to offer consistent performance and long operational life. On paper, the output power is rated at 10 Watts + 10 Watts at 6 ohms, but in practice, the sound satisfies even the most demanding listeners.

LUXMAN provides three line inputs and a phono section that supports both moving magnet and moving coil cartridges, eliminating the need to purchase a separate MC preamp. The RCA connectors are gold-plated and spaced at 18 mm to accommodate high-end cables. To minimize signal crosstalk between the left and right channels, the same input selector IC used in our flagship C-900u control amplifier is employed. For ultimate sonic purity, the Line Straight mode allows bypassing the Bass, Treble, and Balance controls. Additionally, the headphone output is ideal for late-night listening.

The aluminum remote control allows volume adjustment and can also control a LUXMAN CD player, such as the matching LUXMAN D-N150 digital player. The 5 mm thick aluminum chassis has a compact footprint of just 210 x 297 mm (8-1/4 x 11-3/4 inches), excluding protruding parts. The blasted white finish contrasts elegantly with the fine lines on the machined aluminum controls. The orange LED lighting of the analog level meters provides a visual counterpoint to the glow of the vacuum tubes, completing the amplifier’s distinctive aesthetics.
