Earthquake Sound Cinenova Grande Multi-Channel Power Amplifier with Class A Bias



Earthquake Sound is renown for producing powerful amplfiers, in part because they started in the car audio business, where high power is what customers want. They branched into home audio and began marketing multi-channel power amplifiers for the home theater market. We reviewed the Cinénova Grande in a five-channel configuration in 2004, and the seven-channel version in 2006. In both cases, the rated output per channel was 300 watts RMS.

The latest iteration is rated at 360 watts RMS output per channel.
