Anthem unveiled four new A/V receivers at the show—the MRX 300 ($1000), 500 ($1500), 700 ($2000, shown here beneath the BLX 200 Blu-ray player), and 900 ($4000). The big news here is that all four include Anthem Room Correction (ARC), previously available only in the company's high-end D2v ($8500) and AVM 50v ($6000) pre/pros. Also, all provide HDMI 1.4a connections (seven inputs in the 900, four in the others, one output on all models) with 3D pass-through, Audio Return Channel, and Ethernet over HDMI in a firmware update scheduled for November
