Luxman SQ-N150 Vacuum Tube Amplifier

Product Number: SQ-N150

Music reproduction of uncanny warmth and beauty

In the 1960s, when the audio industry moved en masse into transistor amplifiers, LUXMAN stood apart. We recognized the ineffable beauty of vacuum tube audio, and we’ve continued to build tube components without interruption. Part of LUXMAN’s NeoClassico II Series, the SQ-N150 is the latest heir to that proud tradition, delivering music reproduction of exceptional warmth and clarity.

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.

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.
