Perhaps the best site of all is AVS Forum. That is my bible for all things Home Entertainment.
I've been a dedicated fan of AVS for several decades. But I wouldn't call it the "bible for all things Home Entertainment", because the information there is all from fanboys of their favored equipment and is 99% opinions. It is a great place to get opinions, that's for sure. But you still should verify everything from the manufacturer. Once in awhile, you will find a large consensus of a bug or problem that is not reported elsewhere and that's why AVS opinion forum can benefit you. It's hard to find consensus there that favors one product over all others.
