Product Description

Special Offer : Includes Free Black Rhodium INTRO XLR 1m Cable

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.

Features

Truly Balanced
The signal path stays truly balanced using the XLR inputs and becomes truly balanced using the RCA inputs.

Ferrum Power Link
OOR performs very, very good right out of the box. But OOR is made to excel above and beyond when used together with HYPSOS. Ferrum use what Ferrum dubbed Ferrum's Ferrum Power Link (FPL in short) to connect the two. HYPSOS then will perform to its maximum, unleashing unheard musicality from the combination with OOR.

Enhanced transparency
The whole design is focussed on a balanced and very transparent sound signature, making listening fatigue something of the past.

Ease of use
only three knobs on the front panel to control the most important settings.

Superior control
perfected steering of output transistors protect them and never let them turn off, therefore reducing distortion to inaudible levels and keeping them in a state where they can instantly unleash all their power, crucial for high dynamics, superlative control and authority in sound.

Discrete design
The discrete power amp technology is developed in-house to achieve the best possible analogue quality.

BEST IN CLASS 2021-22

FERRUM'S COMPACT AND elegantly styled amplifier supports balanced and unbalanced headphones, but eschews digital input connectivity in favour of an all-analogue approach on XLR and RCA. Add to this a lack of user features beyond gain adjustment settings and preamp functionality and it has an air of simplicity - but there's nothing simple about its performance. The OOR sounds unusually open and direct, as well as powerful. Headphones are driven hard but extremely cleanly, bringing dynamism, detail and musicality to your personal listening.
