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.
