Product Summary
The Fezz Audio Supernova Magnetar Dual Mono Power Amplifier is a flagship stereo valve power amplifier designed for reference-level systems that demand scale, authority and refinement. Sitting at the top of Fezz’s Supernova range, it delivers true dual-mono architecture within a single substantial chassis, giving each channel its own independent signal path, power supply and output stage.
Built around eight KT150 output valves, supported by 6SN7 and 12AX7 driver valves, the Magnetar delivers 200 watts per channel with the musicality of valve amplification and the drive required for demanding loudspeakers. Its fully differential analogue circuit and Signature Line transformers are designed to preserve low-level detail while maintaining impressive dynamic control.
The Magnetar’s precision-milled aluminium chassis provides rigidity, shielding and resonance control, while premium internal components such as Mundorf capacitors, WBT speaker terminals, Neutrik XLR inputs, pure Teflon tube sockets and microcontroller-based auto-bias support long-term performance. It is a statement power amplifier for customers building a truly high-end two-channel system.
