About the Rogue Audio Atlas Magnum v3 Rogue Audio, handcrafting high-performance tube electronics in Brodheadsville, Pennsylvania since 1996, has built a worldwide reputation for combining genuine high-end performance with real-world reliability and exceptional value. The Atlas Magnum v3 is Rogue's dedicated stereo tube power amplifier — a beautifully engineered push-pull design that delivers powerful, controlled, and deeply musical sound, and serves as the ideal partner for a tube or solid-state preamplifier in a separates-based system. The Atlas Magnum is built around a quartet of KT120 output tubes — one of the most robust and linear output tubes available — operating in an ultralinear push-pull configuration. The v3 designation reflects the latest iteration of the circuit, featuring improved output transformers, upgraded internal wiring and coupling capacitors, and refined bias circuitry for greater reliability and sonic performance. A switchable triode/ultralinear mode allows tailoring of the amplifier's character: ultralinear for maximum power and grip, triode for a more intimate and harmonically rich presentation. The Atlas Magnum v3 is a versatile, powerful, and rewarding amplifier that will drive a wide range of loudspeakers with authority and musicality.
