answers3: If the RCA comes with a blu ray player and 5 speakers and a
sub you have what they call a home theater. Your surround sound will
only be good if you play a movie or listen to a cd. <br>
<br>
A receiver will allow you to connect any device in the home, ex.
satellite receiver, vhs, ps3 and dvd player and so on. Everything will
have s/s because it connects to the a/v receiver and then to the tv.
<br>
So anything viewed on the tv will be in s/s as long as the movie or tv
show was filmed that way. Even if it wasn't, the sound will be better
than a home theater. The cost will be more, it just depends on what
you want. <br>
<br>
Most people start with a theater in a box and upgrade later. Some
people never upgrade and enjoy what they have.
