Amazon offers the Onkyo 665-watt 7.2-Channel Network Home Theater Receiver, model no. TX-NR626, for $299 with free shipping. (Newegg charges a buck more.) Although we saw it for $24 less last month, that's the lowest total price we could find by $77. It features 95 watts per channel into seven channels, 4K video pass through, 802.11n wireless, Bluetooth, six HDMI inputs, and two HDMI outputs.
Update: As a reader found, Fry's offers it for the same price.
