Excerpt: Right out of the gate, we should say that among home theater in a box systems , the Onkyo HT-S9400THX is arguably the best deal on our side-by-side comparison chart. The features you get for the dollars you spend weighs heavily in favor of features.
Pros: The system includes a microphone that auto calibrates satellite speakers for optimum performance.
Cons: The video capabilities of this unit don't allow you to view movies in their native 24fps format.
Excerpt: We'll have to admit that we needed to look up THX I/S+ certification on the Onkyo HT-S9400THX. First, I/S stands for Integrated System. So basically anything that has an A/V receiver and speakers qualifies. The plus doesn't indicated that it is better than regular I/S certification because there is only the plus version so we're not so sure what exactly the "plus" means.
