Sony last week introduced two new AV receivers and a home-theater-in-a-box (HTiB) with an emphasis on high-resolution audio. This means they can support digital-audio resolutions well above that of CD audio and any compressed formats such as MP3. (Two lower-cost AVRs were also introduced, but they have no high-res capabilities.) The top-tier STR-DN1050 and step-down STR-DN850 can support audio resolutions up to 24-bit/192 kHz WAV (uncompressed) or FLAC (losslessly compressed). The 1050 also supports DSD (Direct Stream Digital), the digital-audio format used by SACD. A USB port provides the input for high-res files as well as iDevices. Audio quality is enhanced with a more stable and optimized chassis, high-capacity transformer, and large capacitors.
On the video side, both models offer 4K/UHD upscaling and pass-thru via HDMI (six inputs on the 1050, five on the 850), including at least one that is MHL (Mobile High-definition Link) compatible. The 1050 also provides a fully independent second zone with HDMI output, IR repeaters, and powered and line-level audio outputs. Any source connected to the AVR can be independently accessed from the second zone, including streaming services such as Music Unlimited, Pandora, and Spotify as well as AirPlay and Bluetooth sources. Near-Field Communications (NFC) makes it simple to stream content from a mobile device by simply touching it to the AVR. Both models are 7.2-channel AVRs; the 1050 delivers 165 watts per channel, while the 850 provides 150 Wpc. The 1050 will carry a price tag of $599, and the 850 will be $499 when they start shipping in May. http://www.sony.be/nl/electronics/av-ontvangers/str-dn1050 http://www.sony.be/nl/electronics/av-ontvangers/str-dn850
