Soulution 331 Integrated Amplifier

High-End Engineering in a Compact Form

The Soulution 331 combines a top-tier preamplifier and a reference-class power amplifier in one refined unit. It shares much of its DNA with Soulution’s 3-series and 5-series components, using ultra-fast amplifier technology and a discrete, zero-feedback signal path. This ensures ultra-low distortion and an incredibly wide frequency response.

Every detail, from the power supply architecture to the high-current output stage, is engineered for maximum musicality. The result is a breathtakingly open, natural, and transparent sound — whether you’re listening to chamber music or electronic beats.

Performance That Defies Expectation

With 120 watts per channel into 8 ohms (240 watts into 4 ohms), the Soulution 331 has the authority to drive even the most demanding loudspeakers with ease. Thanks to its fast, high-bandwidth design, transients are rendered with pinpoint precision and bass control remains tight and deep under all conditions.

You’ll experience a holographic soundstage, remarkable tonal balance, and the kind of microdetail usually reserved for much more expensive separates. The 331 reveals every nuance of the recording while staying completely faithful to the source.

Advanced Technology, Intuitive Operation

The Soulution 331 integrates the latest proprietary circuit technology developed by Soulution, including:

• Balanced and unbalanced inputs for flexible connectivity

• Ultra-short signal paths for the highest fidelity

• Powerful 1,000 VA toroidal transformer and over 100,000 µF of capacitance for uncompromised dynamics

• Discrete gain stages with ultra-fast slew rates for crystal-clear resolution

Despite its high-end complexity, the 331 is easy to operate via a clean front panel interface or remote control. Optional phono and DAC modules are also available, allowing you to tailor the amplifier to your system’s needs.

Designed and Made in Switzerland

As with all Soulution products, the 331 is hand-built in Switzerland with meticulous attention to detail. The elegant aluminum chassis not only looks stunning in any environment but also ensures optimal thermal and mechanical stability. Each unit is rigorously tested before leaving the factory, ensuring flawless performance right out of the box.
