what cable do I need?
can I hook PS3 to my Bose System 123 home theater ??
If so what kind of cable to I need
As long as your home theatre system has the proper connections, you should be able to connect it. I have the 5 monster cables connected to HDTV from PS3 since it doesn't have HDMI connection and home theatre system/dvd also connected through monster cables as well going to the TV also. Check manual of system and/or tv for proper setup. From what I hear the audio is the main difference between HDMI and component cables and some sharpness to video but not much. Remember PS3 has several cable selections and before you spend around $70 on cables(HDMI), make sure your system (theatre/TV) has the proper connection.
