NuVo Technologies is sure proud of its new Essentia E6G whole home audio system, but rather than waxing rhapsodic about its lengthy list of features, it chose to boast about its newfound Energy Star rating. Aside from the being an apparent power sipper, the E6G also touts Philips Class D digital audio amplification (40-watts per zone), an RS-232 bidirectional control interface, 1U rack height, a newfangled control pad, OLED display and support for six sources and an equal number of zones. Of course, we sure hope you save a few dollars on that energy bill if you plan on picking this up, 'cause you'll be shelling out $2,299 up front before ever plugging it in.
