While Onkyo/Integra do make good higher end and good mid priced bang for the buck avr's, the NAD seems to be closest to seperates in one unit. Not your average mass produced receiver. NAD places as much importance in 2 channel applications as it does HT. If I could afford the NAD T785, I would buy it yesterday.
I know professional reviews are not everything, but take a look at the bench test section. NAD's published specs are with all channels driven not just two as other mass market companies publish.
