Ferrum ERCO Balanced DAC & Headphone Amplifier
Highlights
- Ferrum ERCO fully balanced headphone DAC/AMP
- Proprietary IC power amp design
- Proprietary optimised-for-audio digital inputs
- Proprietary optimised MQA rendering and decoding for ARM chip
- Proprietary 4-pin Ferrum connector for HYPSOS
- Balanced 4,4mm jack and unbalanced 6,35mm jack headphone outputs
- Balanced XLR and unbalanced RCA line outputs
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 OORâs magic to lay the first bricks for ERCO. Then we proceeded to add our culminated 20 yearsâ 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.
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 perform to their max.
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 something 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.
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.
ERCO comes with a carefully selected DC power adapter. To get the most out of ERCO you can connect it with HYPSOS using our proprietary Ferrum Power Link DC power cable. This FPL cable can be ordered separately.
