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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementor-element elementor-element-0d4a1c4 elementor-widget elementor-widget-text-editor\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003cp\u003eOOR 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.
