The first question you have to answer is "Why"? The second question is "What I want to achieve"?
Both Bose and Panasonic are audio-playing devices. They either produce sound from eg FM or CD/DVD, or from external source like tape recorder or iPod.
On the other hand, "Home Theaters" are well-known to be "closed system", with their limited connectivity, playing little else that what they already have built-in.
