This doesn't exactly answer your question, but two years ago I owned a Kenwood VR-510 (http://www.kenwoodusa.com/product/product.jsp?productTypeId=55&sortBy=name&pageId=2&productId=752). The Kenwood was THX, had Dolby Digital, DTS, and Circle Sound. I was extremely happy with it until I did a one-to-one comparison with a used Harman Kardon I bought to resell. The HK was fuller and brighter than the Kenwood and had more available headroom, even though the Kenwood had better numbers on paper. Also, I found out later the Kenwood had trouble processing some DD tracks. To make a long story short, I was disillusioned with the Kenwood, and after several different swaps, I settled on my current Outlaw 950 and Parasound amp combo. Granted, I'm comparing a $450 to a $2000 set-up, but given the quality issues surrounding Kenwood, I would lean toward the Outlaw. But don't rule out Onkyo, they make some really nice stuff.
