Product Description

Ferrum ERCO 

DAC, Preamplifier & Headphone Amplifier 

Welcome to the ERCO, which is pronounced ertso not airco. The ERCO was developed by the team at Ferrum by borrowing technology from their world famous OOR headphone amp, using their own 20 years of experience building DAC's and implementing the award winning HYPSOS power supply technology to create this state of the art product. With all of these things combined they have knocked it out of the park. The sound is exactly how you would expect it, honest and detailed with a richness that would go up against the best of the best. All at a reasonable price-point and the ability to take it even further if you want to buy their own HYPSOS Power Supply. Using that together with the ERCOS you will have more detail and headroom than some of the worlds most expensive products. This is on display in our showroom for you to demo today. 

 
ERCO comes with a DC power cable that has been carefully selected by the team at Ferrum however . To get the most out of ERCO you can connect it with HYPSOS using our proprietary Ferrum Power Link DC power cable. This FPL cable can be ordered separately.
