Onkyo has just announced the addition of the HS-S9400THX to their lineup of home theater systems. The top-of-the-line model, the HT-S9400THX is THX Certified and packs THX approved 7.1-channel speakers, making sure you never miss a line of a movie or a note of a song. In addition to the surround sound system, it has the standard features found in their high-end HT systems. A front-panel USB port (with iPod/iPad/iPhone support), Ethernet networking capabilities to support audio from a PC, Internet radio support and compatibility with Windows 7 and DLNA. It also features Marvell Qdeo 4K video upscaling processor, future proofing the device just in case you get a 4K-capable screen in the future. The HT-S9400THX will be available in May for $1099.
