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.
