Hi to everyone. I'm complete ignorant in terms of surround sounds. I'm going to buy my first one and for black friday, circuit city is offering the Onkyo 506 with a set of Energy 5.1 take classic for 599. I was wondering how good is this system. I don´t need much power and is about the budget I was expecting to spend. Also... Can I arrange a 7.1 system to work as a 5.1??? I really don't need the 7.1 arragement and I don't want that many speakers. Thanks.
