Product Highlights

Rogue Audio Atlas Magnum III Power Amplifier — Output Wattage: 100 Watts per channel (60 Watts per channel in Triode mode). Handcrafted in the USA, this high-performance stereo tube power amplifier delivers exceptional dynamic authority and musical transparency. Built around a push-pull circuit using four output tubes with two 12AX7 and two 12AU7 driver tubes, it features a massive linear power supply and custom transformers with dedicated 4 and 8-ohm taps. A rear-panel switch toggles between high-power Ultralinear mode for maximum dynamic control and Triode mode for a smooth, liquid midrange. Additional highlights include slow-start turn-on sequencing to protect tubes, a heavy two-ounce copper circuit board, and an integrated bias meter for easy maintenance.

Reviews widely acclaim the Atlas Magnum III for punching far above its class, earning Stereophile Recommended Component status. Critics praise its holographic soundstage, low noise floor, and articulate bass, noting that it seamlessly combines classic tube liquidity with impressive speed and power. Reviewers frequently highlight the versatility of switching operating modes to match different musical genres, along with the convenience of its built-in bias adjustment system.

Integrating this amplifier into your system provides reference-grade tube performance with effortless power and long-term reliability. Selectable transformer taps ensure ideal speaker matching, while dual operating modes offer two distinct sonic signatures in one handcrafted American chassis. For audiophiles seeking high-end realism, authoritative power, and hassle-free operation, the Atlas Magnum III stands as an exceptional centerpiece for any audio setup.
