Considering the Onkyo TX-NR646's generous feature set and superlative sonic skills, it's one heck of a value.
The Onkyo TX-NR636 offers a compelling mix of features and performance with "future-proofing" that is unparalleled for the money.
Onkyo's TX-NR535 receiver offers decent home-theater performance and a useful number of streaming features, but it's not the last word on value.
Onkyo's TX-NR525 is a solid AV receiver value, especially considering its affordable accessories, but competitors offer integrated wireless features for not much more.
The Onkyo TX-NR616 is a tremendous AV receiver value, with eight HDMI inputs and a very low street price, although Onkyo's step-down models may be an even better buy.
Yamaha's RX-V665BL includes more features than its predecessor, but it doesn't sound as good, has poor video upconversion quality, and doesn't let you assign digital-audio inputs.
