The ES receivers are all designed around a new construction platform, digital board and a wide band power amplifier to maintain the purity of the audio and video signals by minimizing external vibrations and internal jitter.
The new models utilize a xross media bar-inspired graphical user interface for easier content navigation, Sony?s Digital Cinema Auto Calibration for simple surround sound setup, and BRAVIA Sync for Theatre for easy synchronization of compatible home theater components.
Sony?s DIGITAL MEDIA PORT adds control, networking and connectivity options for music playback through various accessories, including a Cradle for iPod (TDM-iP10), a Network Walkman cradle, a PC client device and a Bluetooth adapter (each is sold separately). The models are also Sirius? and XM Connect-and-Play Ready.
