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.

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.\u003c\/p\u003e\n\n\u003ch2\u003eThe Name\u003c\/h2\u003e\n\u003cp\u003eThe name ERCO (not pronounced airco but ˈert͡so) is Esperanto for ore. We took to Esperanto for the name inspired by its creator Ludwik Lejzer Zamenhof, who used to live around the corner from our offices near Warsaw. Zamenhof started developing Esperanto in his childhood while still in school, pursuing peace around the world where one language would bring together humankind. We want to do the same through pure and honest music reproduction. In the end it brings peace to the mind.\u003cbr\u003e\n\u003c\/p\u003e\n\n\u003cp\u003e\u003ccite\u003eMarcin HamerlaFounder and CEO HEM\u003c\/cite\u003e\u003c\/p\u003e\n\n\u003ch2\u003eUnique output cable design\u003c\/h2\u003e\n\u003cp\u003eTwo wires deliver the power and two wires provide the feedback to ensure flat voltage at every moment.
