Yamaha has outed a new high-end home theater in a box to ensure that whatever audio / visual device you use, it'll sound amazing. The YHT-679BL includes an Ethernet port for internet radio, networked music and pulling down AirPlay tunes. It's got an iOS, Android and Kindle Fire-compatible app and there's even a USB port up front that'll charge your device as you use it. Offering 4K HDMI and pass-through 3D video, the unit's clad in piano-gloss black, while a 6.5-inch, 100W subwoofer will add some floor-shaking to the two tower and three satellite speakers that are included. It'll set you back $650, plus whatever it costs to get some soundproofing done once your annoyed neighbors are done with you.
