Hell everybody... I will be getting a pair of the Athena AS-F2 Floor Speakers, the Athena Center Channel, and I have an old Bose system, probably 8 years old. But I have the satellite speakers from that set. I won't be getting a sub yet. I have no clue what type of reciever I need. I want a good quality one. But unfortunetly I want to keep it under $400. Any ideas?
