The Product Philosophy 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 result 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. Over 30 years now, OCTAVE has been building high-quality tube amplifiers that offer stable performance and reliability on par with the finest transistor equipment. Our models owe their outstanding durability to the well thought out electronic monitoring and protection systems. The soft-start technology, the controlled “power rise”, precise stabilization and intelligent protective circuits are the guarantors of unsurpassed product reliability. After all, with an OCTAVE amplifier, music lovers should be able to listen to their records and CDs – at the highest performance level possible – for decades. Every OCTAVE amplifier is based on high-quality components – from the input jacks to the output transformers – which are developed and produced by OCTAVE. Each and every model is meticulously hand-built at our company headquarters in the Baden village of Karlsbad, Germany. Before any product leaves our facility, it must first pass stringent quality-control and a 48-hour durability test. OCTAVE models are engineered to provide a long life-time of unwavering sound quality. As most of the mechanical and electronic components of our products are engineered in-house and produced according to our strict directives by specialized manufacturers, we are able to use original components should service ever be necessary, even if an older model should require repair, thereby offering our customers the highest quality service possible and products that maintain stable performance and maximum value. Our model philosophy is based on the continuous development and refinement of our products. The best example perhaps is our HP 500 preamplifier, which successfully maintains its presence in the market since 1986 – not least thanks to the fact that the preamplifier can reap the benefits of the technological advances. That we are absolutely right with this concept is confirmed by the intensive, personal dialog with our customers. We view the numerous group-test wins and awards by the hi-fi press as validation of our efforts. But they are also serve as encouragement to consequently pursue this avenue even further.
