What's New
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. So what did we improve?
