Cables for B&W 683s

Hi, I am a new member to this forum and had some questions regarding which cables should I use for my B&W 683 speakers. I have the option of using Kimber cables (8TC) or QED Anniversary XT for the front channel speakers. I was wondering if I need such expensive cables or any oxygen free cables would do for the system? I would also like to know what connectors should I use for the system, Banana plugs or spade connectors. These would be either Monster or Kimber. My configuration is as follows: 2 - 683 speakers (front channel) 1 - B&W HTM-61 as centre channel 2 - 686 for surround 1 - Def. Tech. Supercube 1 bass unit 1 - Denon 3808 A/V receiver 1 - Playstation 3 1 - Panasonic AE2000 Full HD projector Thanks for any help. Regards, Aditya
