Description / Ferrum Audio ERCO Gen 2 Desktop Headphone Amp/DAC
With the full reprogramming of ERCO’s software in combination with crucial changes in the analog circuitry, Ferrum Audio is introducing a newer and better ERCO. The ERCO Gen 2 will bring the entry-level ERCO DAC one step closer to the performance levels of WANDLA, Ferrum Audio's flagship converter.
Improvements brought to you by ERCO Gen 2
The I/V converter stage has better overall performance. SERCE’s DSP engine provides oversampling using DDF preferred HQ Apodizing digital filter, which get the most out of the ERCO's DAC chip almost emulating WANDLA performance.. The maximum sample rates supported by the ERCO GEN 2 are now PCM 768 kHz and DSD 512.
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 favorite headphones to the balanced 4.4 mm jack or unbalanced 6.35 mm 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
The ERCO GEN 2 incorporates a 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 well right out of the box. But ERCO is made to excel above and beyond when used together with HYPSOS. Using the 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.
