Double the Current, Same Purist Soul: Soulnote M-3X

The Soulnote M-3X is the higher-current evolution of Soulnote's M-3 monoblock — a completely non-NFB monaural power amplifier that, in the company's words, "doubled the current delivery capacity without compromising spatial expression or penetrating power." Sold individually for true dual-mono systems, each M-3X delivers 240 watts into 2.7 ohms with the grip to command even the most demanding loudspeakers, while keeping Soulnote's signature vivid, three-dimensional presentation intact. Priced per unit; two are required for stereo.

Minimalism as Engineering

The voltage-amplification stage uses Soulnote's new Type-R non-NFB differential circuits built from the barest possible parts count — just four bipolar transistors and ten resistors — because every component removed is a component that can't smear the signal. Precision-paired output transistors, matched using a newly developed method, deliver "blur-free parallel push-pull" performance. An ultra-low-loss 1600 VA non-epoxy toroidal transformer is mounted vertically on titanium washers, and the amplifier does one thing only: a single XLR input and speaker terminals, with no selectors or microcontrollers to get in the way.

Why You'll Love the Soulnote M-3X

• Doubled current delivery vs the M-3 — 240 W into 2.7 ohms of iron grip
• True monoblock — one amplifier per channel (sold each)
• Minimalist non-NFB Type-R — just 4 transistors and 10 resistors in voltage amp
• Precision-paired push-pull — newly developed matching for blur-free output
• 1600 VA toroidal on titanium — ultra-low-loss, vertically mounted
• Single-function purity — one XLR input, speaker terminals, nothing else
• Hand-built in Japan — Premium Silver or Premium Black, 31 kg each

Frequently Asked Questions

Is the M-3X sold as a pair?

No — each M-3X is a single monaural amplifier sold individually. Two are required for a stereo system, giving you a true dual-mono pair.

How does the M-3X differ from the M-3?

The M-3X roughly doubles the M-3's current-delivery capacity (240 W into 2.7 ohms vs 160 W into 4 ohms), for greater control of difficult, low-impedance speakers — without sacrificing the spatial, penetrating Soulnote sound.

What does it need to run?

A preamplifier or DAC-preamp (such as the Soulnote D-3) connected to its single XLR input.
