I am considering purchasing a Yamaha home theater package that includes a six speaker surround sound system. Does anyone have any experience with the quality of the Yamaha systems? I am not sure whether I should buy the one with the built in dvd player, with the free standing dvd player, or the one with none. If I choose none, I would purchase an add on of course. Also, I am not sure if the higher power levels translate to better sound quality or not. I have been told that they almost always do and vice versa. Any information would be approceiated. Thanks.
