Each of the components uses Modular Design Construction and focuses on making music sound the very best that it can.
The folks at NAD make receivers that are good for every purpose you can put a receiver to, but that doesn't mean they're generalists. You can watch movies and TV, but the primary focus of NAD's receivers and preamps is to make your music sound better than it ever has before.
Their $3,000 T 777 and $4,000 T 787 receivers achieve this by including a 24-bit/192kHz Burr Brown DAC and multiple high-power DSPs for optimal audio. You'll also find the EARS (Enhanced Ambience Retrieval System) mode which adds a bit of spacial ambience to stereo tracks.
The T 187 is the latest preamp/processor from the company and comes in at $3,000. Like the 777 and 787 it employs the Burr Brown DAC and the EARS audio system. It also gives you seven HDMI inputs, IP control, IR outputs, 12v triggers and an RS-232 port.
