Question: help please? HT Z320

I have read the reivews and this is easily the best review this system has gotten from the sites i have visited. I have read mostly positive reviews those so that gives me hope. Anyway I have got this system for Christmas after asking for the previous model. I just want to make sure before I open it it is all the previous system and more. I m getting this system to go along with a PS3 and I was hoping that it still provided the same quailty and sound that the same one did.
