Dynamic Performance with Tube Power
The Atlas Magnum III delivers an energetic and full-bodied sound that is immediately engaging. With 100 watts per channel in ultralinear mode, it has enough headroom to handle complex passages and loudspeakers with challenging loads. Switch to triode mode, and the amplifier offers a more refined, intimate experience—ideal for acoustic music or late-night listening.
Built for the Modern Listener
While the Atlas Magnum III is rooted in traditional tube design, its execution is thoroughly modern. Gold-plated RCA inputs, oversized binding posts, and an easy-access biasing system make integration into any system smooth and straightforward. Whether you’re using vinyl, CD, or streaming sources, the amplifier adapts beautifully to your setup.
American Engineering Excellence
Like all Rogue Audio products, the Atlas Magnum III is handcrafted in the USA with rigorous attention to detail. From the heavy-duty chassis to the precisely selected internal components, every aspect is engineered to deliver long-term performance and reliability. This isn’t just a piece of audio gear—it’s a long-term investment in your music enjoyment.
Flexible and Intuitive Design
Despite its sophisticated circuitry and power, the Atlas Magnum III is simple to use. The built-in bias meter removes the intimidation factor of tube maintenance, while the ultralinear/triode switch gives you tonal flexibility at the flip of a switch. Its intuitive design ensures that you can focus on the music—not on operating the gear.
