Ferrum ERCO

€2.395,00 (€1.979,34 excl. tax)

“Like a top chef who uses his ingredients freshly and grown from his own garden, we integrated parts of the awarded HYPSOS technology and lend some of OOR’s magic to lay the first bricks for ERCO. Then we proceeded to add our culminated 20 years’ worth of experience in making DA converters. And man, did we pull it off. We managed to get the best out of our two winners and put it in our new sibling, adding awesome DA conversion to the mix.”

Description

“The name ERCO (not pronounced airco but ˈert͡so) is Esperanto for ore. We took to Esperanto for the name inspired by its creator Ludwik Lejzer Zamenhof, who used to live around the corner from our offices near Warsaw. Zamenhof started developing Esperanto in his childhood while still in school, pursuing peace around the world where one language would bring together humankind. We want to do the same through pure and honest music reproduction. In the end it brings peace to the mind.”
Marcin Hamerla, Founder and CEO HEM

Clearing the path for high end audio

Perfect mix of flagship Ferrum technology combined with high grade in house developed Digital to Analog conversion. Choose from three digital and one analog input.

Proprietary Technology

Industry leading technology is applied. All digital ports are optimised for audio, MQA decoding and rendering is optimised for use with internal ARM chip.

Suited for high end personal audio

Connect your favourite headphones to the balanced 4,4mm jack or unbalanced 6,35mm headphone jack outputs or powered loudspeakers on your desktop to the XLR or RCA outputs to reach their maximum potential.

Truly Balanced

The signal path is truly balanced from early D/A stage and becomes truly balanced using the RCA inputs.

Discrete/IC hybrid design

Ultra-wideband ICs fine-tuned for audio use to achieve the best possible analog quality.

Enhanced transparency

The whole design remains focussed on a balanced and very transparent sound signature, making listening fatigue a thing of the past.

Ease of use

Hassle-free operation. Only three knobs on the front panel to control the most important settings.

Ferrum Power Link

ERCO performs very, very good right out of the box. But ERCO 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 ERCO. Ferrum Power Link boasts unique output cable design: two wires delivering the power and two wires providing the feedback to ensure flat voltage at every moment. This design 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.
