I'm looking to buy a new system. A couple of nice speakers, what kind? My room is not an auditorium. 12' x 16'. I don't need to blow anyone out but want good bass, clarity, etc. Is there such a sytem? I have an old but in great shape reciever, pioneer 450. Do I buy another, maybe an amp instead? Everybody I am new and just looking for direction. Can anyone help.?

Thanks Bob D
