OOR, the only headphone amplifier with a soul
and a second EISA award!

When our HYPSOS won an EISA award in 2021, we knew we were on the right track and went on to follow our dreams of delivering the best possible audio gear we could think of. When we learned OOR was chosen by the honorable EISA members as best Headphone Amplifier of 2022-2023, all our dreams came true. As did HYPSOS, OOR is a ground-up design without precedent, created from a profound exploration of analogue audio in its purest form. Understated looks married with sophisticated power delivery and amplifier technologies, delivering ultra-low distortion, huge dynamics and unrivaled detail. For those who want to go even further in unleashing unheard musicality, OOR is, of course, designed to pair perfectly with the HYPSOS Hybrid Power System.

OOR will redefine the category of headphone amplifiers. OOR will drive any headphones effortlessly to the max of their potential, while preserving the essence of the music it amplifies. Ultra low distortion, zero fatigue, huge dynamics and unrivaled detail result in ultimate enjoyment. OOR actually makes something that is very difficult to accomplish, seem like the most natural thing on earth. The most important features are:

OOR can be upgraded with HYPSOS Hybrid Power System using our proprietary Ferrum Power Link (FPL) connection, making both units perform to their highest levels. While OOR performs very good right out of the box, it is made to excel above and beyond when used together with HYPSOS. Using the FPL connection means HYPSOS can measure far deeper inside OOR than it can with any other product. Not only does HYPSOS work better in this combination, OOR will also perform even better than it normally does. The truly balanced design of the preamplifier stage coupled with the discrete power amplifier technology in combination with the implementation of highly selected components is elevated to a level of it”s own.
