Engadget: Shortly after introducing its entry-level TX-NR515 and TX-NR616 receivers, Onkyo is taking the wraps off of a fresh pair of souped-up, pricier AV boxes. Both part of the TX-NR family, the TX-NR717 ($999) and TX-NR818 ($1,119) are carrying on the 7.2-channel audio tradition seen on their lower-priced siblings, while a Qdeo processor handles all video upscaling duties — yes, 4K included. The 3D-ready couple is also packing THX Select 2 Plus certification, a whopping eight HDMI ports on each box, DTS-HD Master Audio / Dolby TrueHD decoding and a revamped 1080p GUI. Onkyo’s also said iOS and Kindle Fire variants of its Android Remote App are in the works, though mum’s the word on when they’ll be up for grabs. Either of these good enough for your home setup? They won’t hit shelves until May, which may (baller status) or may not (Average Joe) be enough time to save up.
