The Engström MONICA Mk III is a fully balanced valve line preamplifier engineered to preserve the integrity of the audio signal through an uncompromising analogue design. Designed and hand-built in Sweden, it employs a unique balanced two-totem-pole circuit with no global negative feedback, allowing exceptional transparency, dynamic expression and tonal naturalness while maintaining outstanding drive capability for long cable runs and demanding power amplifiers.

Four carefully selected 5687WA or E182CC triodes in the signal path, transformer-coupled inputs and a dedicated two-chassis design contribute to its clarity, transient speed and exceptionally low noise. A separate power supply with fully regulated voltages isolates the analogue circuitry from control electronics, while comprehensive balanced and single-ended connectivity makes the MONICA Mk III an ideal partner for the finest high-end audio systems.

The Engström M-PHONO is a fully valve MM and MC phono stage engineered to preserve the integrity of the analogue signal through an uncompromising minimalist design. Designed and hand-built in Sweden, it was originally developed as the phono section within the MONICA preamplifier before evolving into a dedicated standalone component, allowing both the phono and line stages to achieve their full performance potential.

A fully valve signal path using four carefully selected triodes, transformer-coupled moving coil input and precision passive RIAA equalisation contribute to its clarity, transient speed and precise retrieval of musical detail. Separate moving magnet and moving coil operating modes, selectable MC loading and a dedicated low-noise power supply allow the M-PHONO to partner a wide range of cartridges while maintaining the natural tonal balance and musical realism that define Engström’s analogue designs.

The Engström LARS is a fully balanced Class A valve monoblock power amplifier engineered to deliver exceptional transparency, dynamic expression and loudspeaker control. Designed and hand-built in Sweden, it employs a transformer-coupled architecture throughout with no global negative feedback, allowing the signal to pass through an exceptionally linear circuit while preserving the natural tonal character and immediacy for which directly heated triodes are renowned.

Twin 300B-XLS output valves, transformer-coupled circuitry and a fully balanced signal path contribute to its clarity, transient speed and precise retrieval of musical detail. Independent monoblock construction, carefully regulated power supplies and hand-selected components ensure exceptional channel separation and low noise, while selectable input sensitivity and output impedance allow the LARS to integrate seamlessly with a wide range of reference loudspeakers and source components.
