Yamaha RX-V863 is 7.2 Channel Home Theater Receiver, boasting 105 watts per channel across all seven speakers. It features full HD 1080p upscaling, with three HDMI inputs and a single HDMI out. Along with supporting cutting-edge video, the V863 also supports the latest in uncompressed audio formats, such as Dolby True HD and DTS-HD Master Audio. It also has iPod and Bluetooth connectivity, as well as HD Radio, XM and Sirius satellite radio compatibility via aftermarket antennas and service plans. The V863 "possesses a lively and energetic sound that adds a bit of swing to music and punch to movies" and it sounds "remarkably good for a receiver in this price class." It is also a better value than most similarly priced receivers because it has more features and options than they do NB! I bought and used this in USA (it is 120 V), but later in Europe (using a step-down voltage converter/transformer that converts the 220V power to 110V). If you are planning to stay some time in US - take it with You. For use in Europe You need to buy additionally converter and adaptor from European plug-in to US.
