ERCO Gen 2 delivers performance one step closer to the WANDLA with a new I/V converter stage and a oversampling using a DDF preferred HQ Apodizing filter.

With the full reprogramming of ERCO’s software in combination with crucial changes in the analog circuitry, we are introducing a newer and better ERCO. The ERCO Gen 2 will bring our entry-level DAC one step closer to the performance levels of WANDLA, our flagship converter. We even created a program for existing ERCO owners to upgrade their units to new ERCO Gen 2 specifications.


The I/V converter stage has better overall performance and SERCE’s DSP engine provides oversampling using DDF preferred HQ Apodizing digital filter, which get the most out of the DAC chip almost emulating WANDLA performance.. Last but not least maximum resolution is now PCM 768kHz and DSD512.

Proprietary Technology

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

Suited for high end personal audio

Connect your favorite 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.

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.

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.

Truly Balanced

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

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.

ERCO Gen2 comes with a carefully selected DC power adapter. To get the most out of ERCO Gen2 you can connect it with HYPSOS using our proprietary Ferrum Power Link DC power cable. This FPL cable can be ordered separately.
