It's that time of year again and we're taking a look at the new receivers. At the $600 price point we have offerings from Onkyo, Yamaha, Pioneer, Marantz, Denon, and Harman Kardon (the TX-NR609, RX-V671, VSX-50, NR1602, AVR-2112CI, and AVR 2650 respectively). Most of these are within $50 of the target price though we gave a slight edge to the Harman offering by choosing an $800 offering. Will they crush the comparison with their extra MSRP? Things to expect at this price point - 3D, Audio Return Channel, HDMI upconversion, networking, tons of power, and two zones of audio. Discuss "2011 $600 A/V Receiver Comparison Guide " here.
