Octave Joins the Definitive Collection

There’s a certain moment when you hear a system come alive and the room disappears. Notes float in the air with weight, voices land with humanity, and suddenly you’re in the presence of music, not equipment. That’s the feeling that first drew us to Octave Audio, and why we’re proud to announce that Octave has officially joined the Definitive lineup.

The Soul of Tubes, Reinvented

For more than three decades, Octave has been quietly rewriting the story of tube amplification. Born in a small town in Germany, these amplifiers aren’t just about glowing bottles and nostalgia. They’re about precision ... tube warmth married to modern stability. Octave figured out how to make tube amps that don’t just sing, but sing for decades without losing their voice. Many of their pieces run flawlessly for 20 years or more, a rare feat in the high-end world.

At the heart of Octave is a simple belief: that amplifiers should serve the music, not themselves. Everything, from their meticulously wound transformers to their hybrid control circuits, is built in-house with that singular goal. The result is gear that feels less like “product” and more like an instrument. Engineered with restraint, built with intention, and voiced with an ear toward timelessness.

This philosophy comes to life in their creations. The Jubilee Class A Mono, revealed to the world in Munich, pours out 160 watts of pure Class A emotion: lush, holographic, and alive, yet with the authority and grip of the most muscular push-pull designs. The Jubilee Mono Ultimate, with its eight KT170 output tubes per channel, pushes the limits even further, delivering power that can tame the most demanding loudspeakers while never letting go of nuance. 

By welcoming Octave into the Definitive collection, we’re adding another voice to the chorus. One that blends warmth and honesty, engineering and art. One that reminds us that while technology moves fast, music always comes back to the same thing: connection.

And now, that connection is closer than ever. Step into one of our listening rooms, let an Octave amplifier light up your favorite recording, and see if you don’t forget the gear entirely. That’s when you’ll know: this isn’t just hi-fi. It’s music, alive.
