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. Click here for more information on the update program. So what did we improve?Improvements brought to you by ERCO Gen 2The 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 768 kHz and DSD 512. Proprietary TechnologyIndustry 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 audioConnect 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 audioPerfect 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 designUltra-wideband ICs fine tuned for audio use to achieve the best possible analog quality.Enhanced transparencyThe whole design remains focussed on a balanced and very transparent sound signature, making listening fatigue something of the past.Truly BalancedThe signal path is truly balanced from early D/A stage and becomes truly balanced using the RCA inputs.Ferrum Power LinkERCO 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 Gen 2 comes with a carefully selected DC power adapter. To get the most out of ERCO Gen 2 you can connect it with HYPSOS using our proprietary Ferrum Power Link DC power cable. This FPL cable can be ordered separately.FEATURESERCO Gen 2 fully balanced headphone DAC/AMPImproved I/V converterImproved DSP engineImproved Digital Filter (HQ Apodizing)Improved max resolution (768 kHz / DSD 512)Proprietary IC power amp designProprietary optimised-for-audio digital inputsProprietary optimised MQA rendering and decoding for ARM chipProprietary 4-pin Ferrum connector for HYPSOSBalanced 4.4 mm jack and unbalanced 6.35 mm jack headphone outputsBalanced XLR and unbalanced RCA line outputsSPECSHeadphone output gain: balanced -5.8 dB, +6 dB, +17.8 dB; single ended -11.8 dB, 0 dB, +11.8 dBOperation: fully balanced, proprietary IC power ampPower inputs: 5.5/2.5 mm DC connector center positive; proprietary FPL 4-pin DC connector (FPL)Analog inputs: RCA (Red Book level 2V RMS recommended, PRO level supported)Digital inputs: USB-C (MQA, up to PCM 32-bit/768kHz, DSD512, DoP256); S/PDIF coaxial (MQA, up to PCM 24-bit/192 kHz, DoP64); S/PDIF optical (MQA, up to PCM 24-bit/96 kHz guaranteed, should work up to PCM 24-bit/192 kHz and DoP64 – depends of user’s optical cable and transmitter)DAC chip: ESS Sabre ES9028PROPCM sample rates: 44.1 / 48 / 88.2 / 96 / 176.4 / 192 / 352.8 / 384 / 705.6 / 768 kHzDSD sample rates: 2.8224 / 3.072 / 5.6448 / 6.144 / 11.2896 / 12.288 / 22.5792 / 24.576 MHzDAC resolution: PCM up to 768k@32bit; DSD up to 512 (22.6 MHz / 24.6 MHz)MQA: decoder and renderer (USB, OPTO and COAX inputs)Headphone jack outputs: balanced 4.4 mm (TRRRS); unbalanced 6.35 mm (TRS)Line outputs: balanced XLR; unbalanced RCA (both Red book level: 4V RMS bal./2V RMS unbal.)Volume control: analogue with bypass option (bypass for line outputs only)Frequency response: 10 Hz – 30 kHz (+/- 0.05 dB); 10 Hz – 200 kHz (+/- 1 dB)Output power unbalanced: 300 mW into 300 Ω; 1.7 W into 50 ΩOutput power balanced: 1.2 W into 300 Ω; 6.1 W into 50 ΩTHD on balanced output: < 0.00018% / -115 dB, 1 mW into 16 Ω; < 0.00018% / -115 dB, 100 mW into 16 ΩTHD on unbalanced output: < 0.00032% / -110 dB, 1 mW into 16 Ω; < 0.00057% / -105 dB, 100 mW into 16 ΩDynamic range analog: 129 dB (A-weighted)Dynamic range digital: 117 dB (A-weighted)Input impedance: 47 kΩOutput impedance unbalanced: 22 Ω on pre-ampOutput impedance balanced: 44 Ω on pre-ampOutput impedance Headphones: < 0.3 ΩPower consumption: idle <15 WPower adapter: 100-240 VAC to 22-30 VDCDimensions (W x D x H): 21.7 cm x 20.6 cm x 5 cm / 8.6” x 8.1” x 2.0”Weight: 1.8 kg / 3.97 lbs

About Ferrum Audio

Ferrum Audio emerged from Poland's Warsaw region as a fresh entrant in the audiophile world, launched by parent company HEM under CEO Marcin Hamerla. Drawing inspiration from local ironworking heritage—where "Ferrum" means iron in Latin and nods to the area's metallurgic past and Hamerla's blacksmith father—the brand embodies Polish craftsmanship fused with high-end audio design. Locally engineered and manufactured, it represents years of accumulated expertise without a specific founding year disclosed, quickly gaining traction since its debut products.

The lineup centers on compact, high-performance desktop and head-fi electronics, spotlighting the HYPSOS power supply as its firstborn, followed by the OOR headphone amplifier, ERCO DAC/amp, and WANDLA DAC. These siblings excel standalone but pair synergistically, especially with HYPSOS, delivering exceptional musicality. Ferrum avoids speakers, turntables, or cables, focusing instead on DACs, amplifiers, and power solutions tailored for headphones and living-room setups.

Positioned as a niche boutique force in the high-end market, Ferrum has surprised the head-fi scene with its iron-clad builds, precise sonics, and value, conquering global dealers from its Polish roots. For discerning buyers seeking uncolored, dynamic audio without excess bulk, it stands as a confident, modern contender.
