DISTORTION, MINIMIZED
Driven by Class A Output Stage Drivers, this preamplifier is a maestro of minimalism, employed to guarantee the lowest Total Harmonic Distortion (THD) and Intermodulation Distortion (IMD). The result? A harmonious soundscape that resonates with authenticity and captures the very essence of the music. The Mimesis Reference defies convention with its mastery over Ultra-Low Transient Intermodulation Distortion (TIM). Every delicate transition, every crescendo, is imbued with a purity that embraces the essence of true fidelity.

POWER, REDEFINED
A complete redesign of the power supply has been implemented, utilizing separate analogue and digital circuits. Custom audio-grade transformers are employed to drive each section of the preamplifier, ensuring optimal performance. Each side (left & right) of the preamplifier has its dedicated power supply, enhancing channel separation.

MASTERY IN DISSIPATION
An additional separate power supply is dedicated to driving the digital section of the preamplifier. The heat sink has been crafted in-house to maximize the utilization of available surface area and efficiently dissipate heat from the power supplies. The power supply units feature customized Goldmund brand components, including oxygen-free gold, guaranteeing an extraordinarily stable sonic power supply for the audio drivers.

CRAFTED TO PERFECTION
Heat dissipation has been enhanced with a meticulously crafted heat sink, created using CNC machining techniques, is implemented. Extensive work has been conducted on the audio board of the preamplifier section. A new shielding design, which also serves as a heat sink, has been implemented. Each Low Noise Op-amp on the audio board is equipped with a custom heat sink. The heat sink is precision machined from a single piece of aluminium, ensuring optimal cooling efficiency by establishing direct mechanical contact between each Op-amp and the dissipator. This configuration provides the best available cooling capability for the audio circuitry.

A NEW ERA BECKONS
Commencing from 2023, our new Pre-Amplifier model embraces a visionary new design language. A ‘No-screw-design’ graces the Top Panel, an ode to aesthetic harmony. The Side Panels draw inspiration from the new active speaker range, exemplifying a seamless blend of elegance and function. In a bold move, the Mechanical Enclosure undergoes metamorphosis, embracing a heightened panel structure for unrivalled durability. With parts now 12mm thick, our precision mechanics shine through, bearing testimony to the exceptional quality that defines our craft.
