Yamaha RX-V665BL photos

From the specs chart, the RX-V665BL's connectivity would seem to be pretty complete, but the specs don't tell the whole story. The RX-V665BL's four HDMI inputs are average at this price point, although it's worth pointing out that the Onkyo TX-SR607 has six. While the rest of the connectivity is in line with comparable models, it's not nearly as flexible some others, as the RX-V665BL lacks the capability to assign audio inputs to any video input you'd like. So, while there are two component video inputs and two optical-digital-audio inputs, it's not possible to use two component video sources accompanied with optical-digital audio, because one of the component video inputs is permanently assigned to a coaxial-digital-audio input. In the real world, this will probably be an issue only if you have many analog video sources, but it's an annoying drawback that isn't present on other receivers in this price range.
