Soulution 312 Stereo Amplifier – Precision Power with Effortless Musicality

The Soulution 312 Stereo Amplifier is engineered for listeners who expect more than just volume. It’s for those who demand control, finesse, and musical integrity—without compromise. Positioned between the award-winning 311 and the reference-class 701 mono blocks, the 312 delivers both power and purity in equal measure.

From the first note, the difference is unmistakable. While many amplifiers struggle with dynamic shifts or complex speaker loads, the 312 handles everything with grace and authority. As a result, your music comes alive—with clarity, energy, and emotional impact.

Key Features That Set the 312 Apart

  • Massive Power with Headroom to Spare
    The 312 delivers 2 × 120 W into 8 ohms, scaling up to 2 × 480 W into 2 ohms. Therefore, even the most demanding loudspeakers are driven with ease, speed, and precision.

  • Ultra-Fast, Wideband Circuitry
    Thanks to its high-speed, low-feedback topology, the amplifier responds instantly to musical transients. Consequently, you get tighter bass, sharper imaging, and a more natural flow.

  • True Dual Mono Construction
    Each channel is completely isolated—electrically, mechanically, and magnetically. This design choice eliminates crosstalk and, in turn, enhances stereo separation, depth, and resolution.

  • Oversized Power Supply for Instant Current Delivery
    At the core of the 312 lies a 3,000 VA transformer and over 500,000 µF of energy storage. Because of this, the amplifier can deliver immense current on demand—without voltage sag or dynamic compression.

  • Silent Background, Pure Signal
    By separating the analog and digital circuits and using ultra-low-noise design techniques, the 312 ensures a pitch-black background. As a result, every micro-detail emerges clearly and effortlessly.

Why the 312 Stereo Amplifier Sounds So Natural

Unlike many high-powered amps that sound mechanical or clinical, the 312 remains fluid and musical—even under stress. That’s because Soulution designed it to track even the smallest dynamic changes with surgical precision. Moreover, its ultra-wide bandwidth and phase coherence ensure that timing, tonality, and timbre are never compromised.

Whether you’re listening to delicate strings or powerful electronic bass, the 312 reproduces every element with remarkable realism. It doesn’t just drive your speakers—it liberates them.


Built Without Compromise

The 312 isn’t just a feat of engineering—it’s a masterclass in craftsmanship. Every detail, from its solid aluminum chassis to its vibration-resistant internal structure, serves a purpose. In addition, all components are hand-selected and tested to meet the strictest performance standards.

Manufactured in Switzerland, the 312 reflects Soulution’s obsession with reliability, precision, and sonic excellence.
