The receiver is 500W 6.1 capable, and with my newest purchase of a Polk Subwoofer and utilizing the Rocketfish Wireless Speaker Kit I could see myself being setup in no time to have a true HD home theatre experience with this extremely cost-effective receiver. The BestBuy salesperson came along and even mentioned how this puppy has the 'Digital Cinema Auto Calibration' feature... naturally I bit and asked 'What exactly does that mean?'.. to which he responded that it has an outboard microphone to optimize the receiver output based on checking and adjusting for the speakers, distances from where you're sitting and sound pressure levels. Sold! Apparently there's a microphone which they include which you simply hook up and place right about where you intend to do your watching / listening from and the receiver auto detects and calibrates the experience to be at an optimal quality based from where you're going to be doing all the popcorn eating.
