As well as the 3D pass-through, the new models have extensive connectivity for custom installation, through conventional infrared input jacks and two-way serial control, plus control over IP. This allows remote set-up and troubleshooting over an Ethernet connection, and simple firmware updates.
The receivers will also stream content from a home network, including internet radio, streaming music and other DLNA content from suitable sources, and the top model, the $2000 STR-DA5600ES, can also work as a DLNA Live Server, streaming music and other content to DLNA-certified clients.
Four Ethernet ports are provided, allowing the receivers to act as a hub for other devices, and two of the the receivers – the STR-DA5600ES and the $1500 STR-DA4600ES – can even output audio and video to a second zone over CAT5 cable, as well as offering 1080p upscaling to the main zone, and 1080i to the second.
In addition, all the receivers can be controlled using a free iPhone/iPod Touch app, which will also 'drive' connected source components.
All three receivers also have Sony's Digital Cinema Auto Calibration set-up system, with Automatic Phase Matching and HD Digital Cinema Sound processing, the range-topping STR-DA5600ES offering DCAC EX, not only adjusting for the usual speaker size and distance, but also the angle to the listening position.
The STR-DA5600ES delivers 7x130W, has six HDMI 1.4 inputs and two outputs (which can be switched, or used simultaneously), and will be available in US stores in September.
The 7x120W STR-DA4600ES has HDMI 1.4 inputs and two outputs, and will go on sale next month, as will the 7x100W STR-DA3600ES, with four HDMI 1.4 inputs and a single output.
All models support all current HD audio formats as well as eight-channel Linear PCM, and have audio return channel capability on their HDMI connections. They also give standby pass-through of all connected HDMI devices, so you can watch sources on the TV without having to power up the receiver.
There's also a new receiver in the company's mainstream range: the $800 STR-DN2010 goes on sale next month, offering 7x110W, 3D passthrough, DLNA client capability with a four-port Ethernet switch and network streaming.
Control via the free iPhone/iPod Touch app is available, and there's audio return channel and the option of wireless rear speaker connection, using Sony's S-AIR system.
Finally, the new 3D ES Blu-ray player is the $400 BDP-S1700ES, with built-in Wi-Fi for access to BD-Live, Sony Bravia Internet Video and the company's new premium video service in the States, Qriocity. It also has SACD playback and the option of being used with Sony's free BD Remote app, which will soon be available for Android devices as well as in its current iPhone/iPod Touch form.
