Ferrum - ERCO Gen 2 + HYPSOS STACK Like a top chef who uses his ingredients freshly and grown from his own garden, we integrated parts of the awarded HYPSOS technology and lend some of OOR’s magic to lay the first bricks for ERCO. Then we proceeded to add our culminated 20 years’ worth of experience in making DA converters. And man, did we pull it off. We managed to get the best out of our two winners and put it in our new sibling, adding awesome DA conversion to the mix. The ERCO Gen 2 headphone DAC/AMP can be upgraded with HYPSOS Hybrid Power System, the same way as flagship model OOR. Using our proprietary Ferrum Power Link (FPL) connection, both units perform to their highest levels. While ERCO Gen 2 performs very good right out of the box, it is made to excel above and beyond when used together with HYPSOS. Using the FPL connection means HYPSOS can measure very deep inside ERCO Gen 2 than it can with any other product. Not only does HYPSOS work better in this combination, ERCO Gen 2 will also perform even better than it normally does. The truly balanced design of the preamplifier stage coupled with the IC power amplifier technology in combination with the implementation of highly selected components is elevated to a level of its own.
