Manufacturer's Description from Summit

Summit Audio's design philosophy with the ECS-410 Everest is a no-compromise, high-value approach to every step of the design and manufacturing process. From the choice of thru-hole parts for high reliability and easy repairs to using gold plated circuit boards, Summit Audio has crafted the ECS-410 Everest for a lifetime of use. The modular design of the ECS-410 Everest makes service and updating extremely simple, as well as giving great separation for each section, with direct power, audio, and ground connections. Each card has double, redundant contacts to the main board and we use actual wire, not failure-prone ribbon cables. All contacts from the cards to the front panel controls use three finger contacts, the most reliable and solid connections available. The inputs and outputs are all fully balanced and use high end connectors in all cases. The steel chassis is very strong and offers excellent shielding with a highly durable coating for a lifetime of use with a minimum of evidence of wear. And most importantly, each section is laid out by hand, so trace routing is the result of experience and testing, not the accidental routing coming from a computer generated 'auto-route' feature. Attention to details like this truly make the ECS-410 Everest stand above.
