I need some help in setting up with a MARANTZ PM 54SE amp with a pair of Tannoy MX speakers and a pair of Jamo S160 surround speakers. I need to set this up over two connected floors connected to a DVD player that will play MP3 DVDS Do I need anything else in this setup, such a subwoofer or a centre channel. The size of the rooms is approx 23 ft X 15 ft. It has wooden flooring and the speakers will have to be wall mounted. I am an absolute newbie and this will be my first setup. Any help & input will be greatly appreciated. Thanks.
