Rootsrockreggae, did you read this review on the NAD? Also, here is a review for the Integra version of the Onkyo. My understanding of the "Audiophiles Welcome?" section at the end of the Integra review is that the unit is a good choice for a simple one box solution, but a little extra effort and expense will result in better sound.
As I previously stated, to use the NAD, you will also need a DAC for digital inputs (TV & iPod), and you can connect a subwoofer to the NAD C316, just differently from the C326.
