I bought a Marantz SR5300 with Paradigm Phantom version 3 floor standing speackers (2), Paradigm ADP version 3 surround (2) and a Paradigm CC 70 version 3 center BUT without a sub and surround center for about 600 US$. I have a few question for the experts: 1. Is this a good deal? 2. Does this system match? For example, can the 5300 drive this particular combination of paradigm to its best performance? 3. DO I have to buy the Sub and the surround center? 4. What would you suggest as the best matching Sub and Surround center for my system for best performance. (I like music more than movies)
