That is how my Panasonic sound box works as well. It really comes down to how sophisticated you want it to be. Cinema surround sound or just a deeper, clearer sound. For most of us the latter is enough. Money left over to spend on other goodies thenWell not at our house!!!! The Bose is 200 notes cheaper and does the job! Unless of course you are a slave to the TV and need super duper wraparound cinema sound. Me? I only need to hear it better than the rubbish speakers on the actual TV.
I think to most human ears the likes of Bose will be more than enough, it is only the geeks that can genuinely pick up any difference. One of lifes little pleasures for me and my daughter is to go into a Bose shop when we pass one, go into the soundproof room and play with the soundbars and speakers. Always sounds fabulous to me
