Kronos AV
The idea behind OCTAVE is a passion for music combined with ingenious electronic attitude and an absolute commitment to perfection. The technically innovative, perfectly manufactured, completely safe and user-friendly amplifiers that offer elegant aesthetics while allowing the beauty of the music and its authentic sound to come alive in living rooms.
What distinguishes OCTAVE? The conviction that true musicality in high fidelity can only be realized with tubes? Surely. But that‘s not the sole factor. The secret of our success lies in the OCTAVE hybrid technology. By that, we mean the optimal synthesis of traditional tube technology and innovative semiconductor circuitry. Tubes ensure the remarkable sound performance of our amplifiers, while our innovative transistor circuits play an important part in enabling the tubes to completely maximize their audiophile potential.

The Jubilee preamp
"...The Jubilee is a true work of art, providing a mastery of the music that is at the limit of what is possible in audio today..." This was the view expressed by Audio magazine when they reviewed the Jubilee preamplifier in June '98 and proclaimed it as their absolute reference. These highly-complimentary remarks attest to the commitment of the OCTAVE design team throughout the development of the Jubilee product. They also validate the conscientious selection of the finest components and the meticulous fine-tuning of the Jubilee’s sound quality. But you deserve to hear the Jubilee for yourself.
