With a fulsome spec, including 3D compatible HDMI sockets, the RXV667 has everything required to satisfy the AV enthusiast. At the heart of this receiver is 7.1 processing. This not only gives you the option of using additional surround sound speakers for an even more enveloping sound, but also the chance to assign the amplifiers for bi-amping, instead. Essentially this means using two of the built-in amplifiers to run your front speakers rather than just one; giving better control with a tighter, more focused sound the result.
With a meaty 90 watts per channel the RXV667 is substantially more powerful than the smaller Yamaha AV receivers. The extra power is clear, especially when it comes to movies with explosive action - the RXV667 can sustain deep bass without it losing clarity or impact. To ensure you don't miss out on what anyone is saying, the RXV667 also comes with Dialogue Lift. As the name suggests, this "pulls" the dialogue forward to make sense of speech over a busy soundtrack.
The other major benefit over and above the RXV567 is full 1080p video upscaling to HDMI. This means that any source you connect into the receiver can be outputted via HDMI. Not only does this improve the picture quality, especially with upscaling to 1080p, but it also means just one HDMI connection between TV and receiver. With the added benefit of an Audio Return Channel, it's now possible to link your TV via just a single HDMI socket and both see the picture from sources and listen to the TV's sound through the receiver. The HDMI sockets are also compatible with the latest 3D formats, letting you use a 3D compatible Blu-ray player via the receiver. In terms of the numbers, the RXV667 has five HDMI sockets at the back combined with a sixth socket at the front - perfect for occasionally connected items such as an HD camcorder.
