Summary: Purchased the receiver, used, but looked new when I received it. Configured as part of a home theater setup, including an iPod dock, and it works great. I use 4-ohm speakers and the amplifier had no problem driving the load.
Summary: This a very fine receiver,I purchased my first unit at Best Buy the sound was great. I purchased another 2 units on E Bay and now I have a system in our living room, a second system in our family room in the basement, and the third system on the second floor.
Summary: This thing is amazing. Right out of the box you plug it in, turn it on, and it works great. There are plenty of input and output options. Then there are advanced features that are well beyond anything I could ever imagine using.
Summary: The Yamaha RX V663 is an excellent 7.2 channel receiver. It not only offers the usual multichannel decoders, but also has Yamaha's excellent DSP functionality. I have owned a Yamaha DSP unit for almost 20 years and when I decided to buy a new home theater receiver and integrate my video and audio systems into a single room, I had to have the DSP features for audio listening that I have had for all those years.
Summary: Though after ordering the Yamaha receiver. The merchant emailed to inform me that they ran out of stock, but upgraded me to a product worth $100 more for the same price. Great merchant, great product. Arrived as scheduled in good order. Will use again.
Summary: This is the first time I bought a home theater system. Weeks of research pointed at this system. I am completely satisfied with it. Good sound, video, individual equalizers per channel, automatic adjustment using supplied microphone, a direct mode for purer sound, and lots of other features I have not used yet. It has enough inputs for my needs and I can spill over additional inputs to my TV if needed.
Summary: SUMMARY: Great Sound, Good video switching, Decodes all HD sound formats, Great DSP features, tremendous value, Pre-Outs upgradable. I was interested in buying an A/V receiver and was undecided between the Onkyo SR606 and the Yamaha RXV663 (aka HTR-6160BL), given what I'd read about them. Both are well known, well liked receivers. The Onkyo SR606 seems more popular due to the number of HDMI inputs, 1080i up conversion (though fairly buggy), and decent performance.
