I want to purchase new speaker/home theater setup (including surround sound, tv, blu-ray player, etc.) for my living room, and I'm going to do it through the local electronics store in my town because I prefer to talk to people and get personal help. Are there any specific things I should ask to make sure the salesman knows what he's talking about? Are there any specific things in-store that I should be looking/asking for? I just want to make sure the salesman is really knowledgeable about these things. Thanks!
