I just purchased (ships the 11th) a new iMac i7. I have been using Dells for years to game with and Macs to work with, and have decided I am not tolerating PC nonsense anymore and moving to my Mac full-time (yay for Bootcamp). I have some old Dell 5.1 speakers that I am retiring, but I am a bit flummoxed on a good set of 5.1 speakers that will work with my Mac. (I do not want to use the Firewave or an external sound card if I can help it.) The Logitech Z-5500 look like they will do the trick with a Toslink To Optical Mini Adapter. However, that is damn pricey for speakers. Do any of you know of some decent 5.1 Surround Sound speakers for the single mini port on the Mac? Yikes. Missed this post. My bad. I had no idea the issue was going to be this complicated. Crap.
