Hello, I'm about to get my iMac, and was wondering about a pair of speakers...the Logitech Z 5540. They have two optical in ports, so it could accept it from the iMac. The problem is that they don't give you a cable with the speakers to do that...do I need a mini to TOSlink cable, such as this one? http://www.futureshop.ca/catalog/pr...ngid=EN&sku_id=0665000FS10061059&catid=11348# Then I would set it up with the mini port going into the iMac with the other end going into the basestation of the speakers. Would this work? Thanks!
