ERCO Gen 2 – closer to the music

ERCO Gen 2 brings Ferrum’s entry-level DAC one step closer to the performance of WANDLA, its flagship converter. Using experience from the SERCE platform, the DSP now equals WANDLA – with 768 kHz support, DSD512, improved DAC performance and WANDLA users’ most-preferred digital filter.

Connect your favourite headphones to the balanced 4.4 mm or 6.35 mm outputs, or powered speakers to the XLR or RCA outputs. A discrete/IC hybrid design, truly balanced signal path and three-knob operation make ERCO Gen 2 a superb high-end desktop hub.

Made for HYPSOS

Performs beautifully straight out of the box, but can be taken further still when paired with the Ferrum HYPSOS hybrid power supply via the proprietary Ferrum Power Link (FPL) connection with 4-terminal voltage sensing.
