This model was considered the Flagship model for Yamaha (not including the Z). The AV receiver has all the bells and whiles including network functionality. Stream music from your computer or station from the web. It also utilizes Anchor Bay Technologies' ABT1010 for upscaling video. For the most part, this piece has the same features as the $600 cheaper Yamaha HTR-6090. One new feature that seems to account for the price increase is Network Receiver function (in addition to the extra power in per channel: 140 Watts per channel). The ABT (Anchor Bay Technologies) ABT1010 scaler engine can independently scale an image horizontally and vertically to further improve the picture quality on high resolution displays (to 1080i/720p with HDMI output).
