Cnet is not necessarily a bad place for reviews
Cnet isn't a bad place for reviews. However, when it comes to speakers they tend to rate things on a value scale and don't really go into a lot of the different speakers brands for comparison.
I have never seen CNET review axiom, rbh sound, or svs speakers maybe hsu research, which is why while a particular model may be rated decent on cnet their maybe much better options out there.
Another good place is secrets of home theater and fidelity

For video projectors avoid places like projector central which is partially corporate sponshorship.
However, CNET is excellent when it comes to reviewing video projectors and tv's because they have a place where they use a geek box to run a lot of tests similar to the candence audioholics and secrets use for dvd players in some ways.
Still though for audio products I would suggest you look at secrets and audioholics, although sometimes there may be products audioholics hasn't reviewed yet.
