To get the most out the combination of OOR and HYPSOS you need to connect them with our proprietary FPL DC power cable. The cable is included in this package.


OOR can be upgraded with HYPSOS Hybrid Power System using our proprietary Ferrum Power Link (FPL) connection, making both units perform to their highest levels. While OOR performs very good right out of the box, it is made to excel above and beyond when used together with HYPSOS. Using the FPL connection means HYPSOS can measure far deeper inside OOR than it can with any other product. Not only does HYPSOS work better in this combination, OOR will also perform even better than it normally does. The truly balanced design of the preamplifier stage coupled with the discrete power amplifier technology in combination with the implementation of highly selected components is elevated to a level of it”s own.

HYPSOS will perform to its abolute maximum, unleashing unheard musicality from the combination with OOR. Combining OOR with HYPSOS really exceeds the sum of the parts and will result in ultimate enjoyment of your favorite music.

Our proprietary Ferrum Power Link (FPL) cable is key in making the marriage of OOR with HYPSOS a happy one. Two wires delivering the power and two wires providing the feedback to ensure flat voltage at every moment. This 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.

Combining OOR with HYPSOS makes everything even better. The two exceed the sum of the parts, pushing both products beyond their respective qualities and outplaying most headphone amps in its price category and then some more.

Review












HYPSOS defines a brand new category of a hifi products. It’s not a simple power supply but an audio component of its own – an equally (or even more) important part of a setup as any other. HYPSOS offers a selection of unique features and even accounts for future software improvements – the device is software controlled with as few hardware dependent elements as possible. 
The most important features are:

Hybrid Power System
Linear/switching hybrid design to get the advantages from both techniques - low ripple and noise as well as fast transient response and high efficiency. 

Distinct user levels 
Using pre-configured settings from the list of supported devices or setting custom parameters manually. Wide continuous ouput voltage range of 5-30V with up to 6A of current delivered to the load. HYPSOS is as universal a device as it gets. 

Sweet Spot Tuning (SST)
Possibility to fine tune the output voltage for the best sound. The voltage level can be safely adjusted on the fly to allow easy comparison testing.

 4T Sensing Design (4TSD) 
Ensuring the exact voltage level precisely at the point of the powered device DC input terminal - special cable design and feedback to ensure flat voltage at every moment. This technique eliminates the harmful effects of the cable's resistance effectively improving transient response. 

Advanced Automation
Compatibility with Apple TV remote, Trigger in/out connector; possibility to automate power-up of the devices with standby mode even without dedicated trigger connection. 

Extremely safe to use
Automatic Transformer Voltage Adjust (ATVA), Electronic Output Voltage Polarity Switch and overvoltage, current limit and short protection. 

Detailed and revealing yet unfatiguing sound
Makes your current audio setup perform to its potential. Tweak the sound modifying the voltage level on the fly and use the preferred combination of the 4-Terminal Sensing and Spread Spectrum Mode settings.

Specification
Power input :110-240Vac/50-60Hz (HK Version)
IEC C14 power inlet, a fuse holder with power on/off switch plus two-stage EMI filter for low impedance load with better noise attenuation in low frequency applications

Power consumption (idle) : TBD

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:

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. Ferrum uses what they 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 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.

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.
