NAD's Flagship AV Receiver
If you look at the back of NAD's new T787 AV Surround Sound Receiver ($3499) you'll see the plug-in modules that make the 120 WPC x 7 unit amenable to future upgrading. As delivered it includes the latest digital video, HDMI, and audio modules. A Control4 Director Series Module is an option. The T187 AV Preamp Processor ($2499) is similarly equipped.
