Hi. I have an iMac G5 and now that the iSub won't work with leopard, I'm thinking of getting a new system. The main ones I am considering are the Soundsticks 2, the Logi Z2300 and the Promedia 2.1 (NOT GMX). I heard that the Promedias have problems with the DIN pins where the speakers will just die, but the Promedias have a tweeter which is better than the Z2300's. The soundsticks use the iSub and also look great, although I don't know how the sound compares to the other 2 THX speakers. I will definitely use the speakers for many types of music and once in a while for games like SWBF or Halo. I don't need the loudest bass because the speakers will normally be on a moderate volume setting. Please help... Thanks in advance.
