    and custom installation requirements? These questions are daunting. And the answers determine the quality and suitability of any modern A/V receiver. The engineers of Sony ES Series don't simply answer these questions. They help drive the technology that brings these questions into being. Thanks

Fiercely independent critics evaluated the Sony STR-DA9000ES receiver using the finest source material and ancillary equipment. Their response was
