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:

 

Features...

  • 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

 

Truly Balanced

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

 

Ease of use

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

 

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. We use what we dubbed our 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.

 

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.

 

Enhanced transparency

The whole design is focussed 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.

 

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.
