Amazon offers the Yamaha 500-watt 5.1-Channel 3D Home Theater Receiver, model no. RX-V375, for $179.95 plus free shipping. That's tied with our mention from two weeks ago, since expired, and the lowest total price we've seen. (It's a current price low by $60.) It features 100 watts per channel into five channels, 4K passthrough, four HDMI inputs, and one HDMI output.
