You can quite possibly enter the realm of the mind-blowing, in your own home, just slip one of the new Onkyo TX-NR717/TX-NR818 AV Receivers into the heart of your integrated, house-wide entertainment cocoon and see what happens! Positioned as mid-level components, their 7.2 channel audio, video and networking features are clearly high end. Both receivers are THX-certified, ensuring an extreme level of audio quality and power, with movie theatre reference. The Dual Core Video Engine employs an HQV Vida VHD 1900 video processor that can seriously upscale and enhance lower-quality content to 1080p, and a Marvel Qdeo processor to upscale 1080p content to four times that resolution. There’s InstaPrevue for video thumbnailing, and a front-panel MHL HDMI port to grab content from compatible smartphones. Networking options are…vast, with eight HDMI inputs and two out, options for Ethernet and wireless, and three-room audio distribution via dedicated line-outs to create separate listening zones, all controllable via iPhone or Android apps. The TX-NR818 offers additional gear like video calibration to ISF standards for precise color accuracy. The TX-NR717 ($999) and TX-NR818 ($1,199) will be available in May.
