Pretty basic system. New iMac 27" and 3.2 gig processor. Creative Labs T-30 wireless speakers. Using iTunes as player. Testing the free trial of Amarra HiFi. I guess my real question was if the speakers are wireless, does it diminish the ability of Amarra to reach its full potential? The change is noticeably better. Crisper and fuller. My impression was that Amarra adjusts the algorithms in which the midi operates.
