Ferrum OOR Fully Balanced Headphone Amplifier
OOR, the only headphone amplifier with a soul
The Ferrum 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 Ferrum OOR is made by a group of very talented engineers and industrial designers, right in the heart of Poland. They like to refer to Ferrum as "Brand of Brothers". OOR is their instrument of choice when they need to completely relax and prepare for their next assignment.
Unique output cable design: two wires delivering the power and two wires providing the feedback to ensure flat voltage at every moment. We named this technique Ferrum Power Link (FPL) and it eliminates the harmful effects of the cable's resistance effectively improving transient response. The current delivery speed at the powered device's input is significantly improved.
The Ferrum OOR comes with a carefully selected DC power adapter. To get the most out of OOR you can connect it with HYPSOS using our proprietary Ferrum Power Link DC power cable. This FPL cable can be ordered separately.
