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.\u003c\/p\u003e\n\u003cp\u003eBuilt 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFlagship dual-mono valve power amplifier designed for reference-level stereo systems\u003c\/li\u003e\n\u003cli\u003e200W per channel output gives excellent scale, authority and control for demanding loudspeakers\u003c\/li\u003e\n\u003cli\u003eEight KT150 output valves deliver powerful dynamics while retaining valve richness and refinement\u003c\/li\u003e\n\u003cli\u003eIndependent signal paths and power supplies help improve stereo separation and soundstage stability\u003c\/li\u003e\n\u003cli\u003eFully differential analogue circuit supports low noise, linearity and fine-detail retrieval\u003c\/li\u003e\n\u003cli\u003ePrecision-milled aluminium chassis helps reduce resonance and improve electromagnetic shielding\u003c\/li\u003e\n\u003cli\u003eMicrocontroller-based auto-bias maintains optimum valve performance without manual adjustment\u003c\/li\u003e\n\u003cli\u003eBalanced XLR and RCA inputs allow flexible system matching with high-quality pre-amplifiers\u003c\/li\u003e\n\u003cli\u003e2 years manufacturer's warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"hb-fezz-magnetar-stereo-power-panel-2\" class=\"hb-panel\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePower Amplifier Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Vacuum tube stereo power amplifier\u003c\/li\u003e\n\u003cli\u003eSeries: Fezz Audio Supernova\u003c\/li\u003e\n\u003cli\u003eArchitecture: True dual-mono stereo power amplifier\u003c\/li\u003e\n\u003cli\u003eCircuit Topology: Fully differential analogue circuit\u003c\/li\u003e\n\u003cli\u003eOutput Valves: 8 x KT150\u003c\/li\u003e\n\u003cli\u003eDriver Valves: 2 x 6SN7 and 2 x 12AX7\u003c\/li\u003e\n\u003cli\u003eTransformers: Toroidy.pl Audio Grade Signature Line by T.
