I'd really like to see a full line of audio/video receivers come out with a host of features like this.
Feature # 1 - a clear motivation toward recogizing HDMI as the primary connection with other connectivity coming in very secondary. There should be a mini-din adaptor or RS-232 port that will allow custom installers to add an analog audio/video switching device controlled by the receiver. it would perhaps be all to easy to have the peripheral to use HDMI as an output with a 1/8" control adaptor to sync the devices. The inside of the receiver should have a powerful processor allowing these expansions to take place without interfering with the speed of the system in terms of switching and detecting signals.
Feature # 2 - The secondary unit discussed above may also have a decent video scaler in it, especially if we are talking about a HDMI based output device. Since most HDMI sources themselves are not in need of being upscaled it would be senseless to have one on the receiver itself, just the accessory.
Feature # 3 - The receiver should use Class D ICE power or similar yet effective technology but on a stripped down level for lower output that can be fit into a small devices such as these newHD receivers. This would give the installer the option to use many different types of in wall speakers and possible full size home speakers if they so wish.
Feature # 4 - The network and wireless capabilities should be part of a third unit. The third unit should have it's own display. I'd like to see the display technology that was used on the DSP-A1000, but I could accept Yamaha's current amber displays. (by the way, the same should follow for the receiver in terms of display type, the analog video switcher doesn't need a display).
Feature # 5 - The units should be stackable. I also believe that the design of the receiver, network device, and analog video unit should be trapazoidal allowing one to flip the analog video device upside down (since it has no display, top and bottom should be bare of anything that would indicate which side is up) to line the units along side one another to leave no void between each component should the installer or user choose to arrange them this way if they have all 3 units.
Feature # 6 - The receiver should contain the connection to the iPod accessory powered by USB. The USB port should allow use with other devices, such as mass storage to allow you to use the receiver as a media server.
Feature # 7 - A wireless zone two amplifier that connects wirelessly to the receiver. The wireless zone two amplifier should also have a display and it's own remote control.
The use of a toroidal transformer inside the receiver is a must, to increase efficiency and save space maximizing the potential power output. Perhaps a wide range of products could be spurred with a similar design philosophy, such as Blu-ray players, double size receivers with bigger amplifiers and more inputs, separates with different amplifier options ranging from a single small box solution to several mono block amplifiers of the same physical size as a single multichannel amplifier.
