Fezz Supernova Magnetar Tube Pre-Amplifier

Product Summary

The Fezz Audio Supernova Magnetar Preamplifier is a flagship valve pre-amplifier designed for serious high-end systems where signal purity, transparency and control are essential. Built around a fully balanced linear circuit and precision-milled aluminium chassis, it is intended to act as the reference control centre for a premium two-channel system.

Using 6SN7 signal valves with a 5AR4 rectifier valve in its stabilised power supply, the Magnetar combines valve musicality with low-noise, wide-bandwidth performance. Its fully balanced topology, premium power supply design and carefully damped chassis help preserve fine detail, dynamic contrast and spatial information from your source components.

The Magnetar offers generous connectivity, with balanced XLR and RCA inputs, balanced and unbalanced outputs, plus a Direct input for integration into suitable system setups. When partnered with high-quality power amplification, including the matching Magnetar power amplifier, it provides the refinement, scale and control expected from Fezz’s flagship Supernova range.
