OOR, THE ONLY HEADPHONE AMPLIFIER WITH A SOUL

OOR Fully Balanced analogue headphone amplifier

  • Proprietary discrete power amp technology
  • Proprietary 4-pin Ferrum connector for HYPSOS
  • Balanced 4-pin XLR and unbalanced RCA headphone outputs

Drive any ‘phones to their maximum capabilities
Ultra-low distortion, zero listening fatigue, huge dynamics and unrivaled detail. Oor makes something very difficult to accomplish seem like the most natural thing on earth.

Simple controls + understated beauty
Characteristically minimalist presentation immaculately finished with Corten steel and
anodized aluminum, and just three control knobs: the small gain knob, the large volume knob, and a toggle for selecting input.

Truly Balanced
The signal path stays truly balanced whether using the XLR inputs or the RCA inputs.

Discrete Design
Proprietary discrete power amplifier technology.

Superior Control
Perfected biasing of output transistors protects them and never lets them turn off,
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.

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

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

The Power Duo: OOR + HYPSOS
Oor goes above and beyond when used together with the Ferrum Hypsos power system. Hypsos can perform to its absolute maximum, unleashing unheard musicality when combined with Oor. Using the proprietary Ferrum Power Link (FPL) connection, the Hypsos can perform its 4TSD voltage-sensing measurements far deeper inside Oor than it can with any other product. The combination enables both units to exceed
the sum of their parts, outplaying many, if not all headphone amps in its price category.

FEATURES

  • Look and behold the understated looks of OOR’s front, only to camouflage its intricate design laid bare on the rear. 100% analogue, 100% natural, 100% musical.
  • Fully balanced from A to Z, even right after the RCA inputs, to get the max out of any headphones. Brightness of the logo on OOR’s front can be dimmed for ease on the eyes. Ferrum Power Link for ultimate connection with HYPSOS.
  • Combine OOR with HYPSOS to unleashing unheard musicality. Together they will excel above and beyond.
  • 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.
  • 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. If the FPL cable isn't already packaged with the HYPSOS, it can be ordered separately.
