Echo Digital Audio is proud to use only specifications
of production units. While other companies quote specs of their converters
alone in laboratory settings, the numbers you see on this page represent
the actual unit in your hands. Since people often rely heavily on specs
when deciding what gear to buy, we like to bring you numbers that really
mean something.
