With our Sony Vaio came Logitech 5.1 speakers. They plug into 5 or 6 color coded ports on the back of the Sony tower. Now that I have the Mac Pro coming (the 27th of Dec.) I was wondering if there was any type of adapter that can be had to route these directly or indirectly, single or dual use) into the Mac and/or PC. If not, any recommendations as to a decent sound system for the Mac Pro? Not over the top, just, a nice sound system that is not budget busting. As always, Thanks.
