Greetings. I have been looking for 5.1 surround sound speakers that will be compatible with the Toslink (digital audio out port) on the PS3. The Logitech X-540 seems like a fantastic choice for 5.1 surround sound under 90 bucks, yet it does not have a Toslink input. I don't think there is a way to convert a Toslink connection to any thing else. Any advice?
