Let's begin with the obvious " THX Select2 certification. It's your assurance that, in addition to the power you'll need to fill average-sized rooms with theater-quality sound (125 watts continuous from each of its seven amplifiers), other performance parameters like signal-to-noise and distortion are absolutely first class.
Then there are the Marantz touches. A toroidal-based power supply. Current feedback amplification. An anti-interference copper plated chassis that's less than 16" deep so it will fit in more places easily.
Adding to the audio flexibility is a 3rd Zone output (with an individually selectable source!) to make your SR8001 the center of a whole house distributed audio system.
On the A/V side, the SR8002 features HDMI switching (version 1.3) for up to four sources and two display devices. And there's format conversion to HDMI with Time Base Correction so even your older video sources will look their best. If you're not quite ready for HDMI (or if your displays aren't), the SR8002 offers two assignable component outputs, too. One infrared receiver input and two IR outputs add enormous control flexibility as do two DC 'trigger" outputs.
Dolby Tru HD, Dolby Digital Plus and dts Master Audio are the next wave of high resolution sound and the SR8002 incorporates the all.
The SR8002 is also one of the few receivers to feature Audyssey's unique auto calibration capability. This is a significant improvement over previous 'room correction" strategies in that it improves the listening characteristics of your entire room rather than for just one or two seats.
In short, the Marantz SR8002 is simply a culmination of everything you've come to expect from us. Refined cosmetics. Sterling performance. Sophisticated advanced to enhance your enjoyment. Let's put this even more succinctly " it's a Marantz!
