LUXMAN SQ-N150 Vacuum Tube Integrated Amplifier

Bring the unmistakable glow, texture, and dimensionality of vacuum tube sound into a beautifully compact, modern integrated amplifier. The LUXMAN SQ-N150 is engineered for music lovers who want classic tube warmth with today’s clarity and control—pairing a highly linear P-K split phase inversion circuit with a refined push-pull output stage for an open, detailed, and engaging presentation. With three line-level inputs plus a built-in phono stage that supports both MM and MC cartridges, it anchors a complete high-end system without forcing you into extra boxes. Thoughtful audiophile touches—gold-plated RCA jacks with generous spacing for premium cables, a Line Straight mode for the cleanest signal path, and a headphone output for late-night sessions—make it as practical as it is musical. Finished in an elegant blasted white chassis with classic illuminated level meters, the SQ-N150 delivers timeless LUXMAN style and performance in an “A4”-friendly footprint.

LUXMAN SQ-N150 Q&A:

What kind of sound can I expect from the SQ-N150?

It’s designed for the hallmark vacuum-tube presentation—natural warmth, rich tone, and a spacious, open soundstage—while maintaining clarity and detail for modern recordings.

Does the SQ-N150 have a built-in phono stage for turntables?

Yes. It includes a phono input that supports both moving magnet (MM) and moving coil (MC) cartridges, so you can connect many turntables directly without a separate MC preamp.

How much power does the SQ-N150 deliver, and what speakers pair well with it?

The SQ-N150 is rated at 10W + 10W into 6 ohms. It pairs best with high-sensitivity speakers or systems designed to shine with lower-powered tube amplification.

How many inputs does it have for sources like streamers and CD players?

It provides three line-level inputs for common sources, plus a dedicated phono input for a turntable.

What is Line Straight mode, and when should I use it?

Line Straight mode bypasses the Bass, Treble, and Balance controls to shorten the signal path. Use it when you want maximum purity and the most direct sound from your sources.

Can I use high-end interconnect cables with larger RCA barrels?

Yes. The RCA jacks are gold-plated and spaced at 18 mm to help accommodate premium cables more comfortably.

Does it have a headphone output for late-night listening?

Yes. A front headphone output is included, making it easy to listen privately without changing your system setup.

What’s included in the box?

The SQ-N150 includes the RA-25 remote control and a power cable.
