Home – OOR – Ferrum
Join the revolution
We at HEM, Polish audio electronics designer and manufacturer and home of Ferrum, started out our adventure with HYPSOS, the category defining and revolutionary hybrid power system. Beginning at the foundation of every hifi chain we set out to create a power supply that would disrupt the audio community. Judging by HYPSOS’ huge success we did just that and enabled users to find the sweet voltage spot for their beloved hifi gear, to name but one of HYPSOS’ unique features.
We succeeded in marrying our unique electronics design with a beautiful industrial design. But as with all great stories, we set out to broaden our horizon. Our next product in line was to bring peace after the initial revolution. Inner peace that is, or peace to the inner ear, to be more exact… After many hours of careful listening and finetuning we present to you our second Ferrum product in line, the stunningly understated Ferrum headphone amplifier called OOR. This is good stuff, you’ll love it.
Combining OOR with HYPSOS
Combining OOR with HYPSOS even exceeds the sum of the parts and unleashes capacities unheard of in both devices. Prepare yourself for musical bliss.
Of course you can use OOR right out of the box to great satisfaction for the most discerning music lovers, but fed by HYPSOS our headphone amplifier will redefine a complete category.
Where to buy
1. Bass is more deep and more precise.
2. Overall sound is more stable/quite, precise and dark.
3. Sound in combination with Brooklin Bridge is a bit like analog.
To me it is clear the a good and clean power supply is not only important for an amplifier but also for other componets in a good audio system like the DAC & Streamer."
