Classic Tube Power, Refined

The Stereo 100 is a true performer in the tradition of high-end tube amplification. Designed to drive even demanding speakers, it delivers a soundstage that’s both expansive and emotionally engaging. Whether you're listening to jazz trios or full orchestral recordings, this amplifier handles it all with finesse.

Choose Your Sonic Character

With triode and ultralinear modes, the Stereo 100 adapts to your musical taste and speaker setup. Triode mode brings a smoother, more liquid presentation, while ultralinear mode offers greater dynamics and punch for large-scale recordings.

Designed for Clarity and Control

Inside, the Stereo 100 features precision-matched tubes, a robust power supply, and carefully laid-out signal paths. These elements work together to deliver excellent transient response and fine detail retrieval across the frequency spectrum.

Simplified Tube Management

Keeping your amplifier in peak condition is easy thanks to Rogue’s integrated bias system. No external meters needed—just use the front-panel meter and onboard controls to set and check bias anytime.

Built to Endure

The Stereo 100 is more than an amplifier—it's a long-term investment in musical satisfaction. From its heavy-duty chassis to its overbuilt transformers, this is a piece of gear built to deliver world-class performance for years to come.
