Hey guys I took a look at some previous threads here which answered most my questions.. from what I could gather, my iMac 24" (3.06 GHz Core 2 Duo, 4 GB memory, one of the newest generations) has an audio out jack that double as an analog/digital out? I have a high end sound system with receiver, sub, speakers, surround, etc. that I want to deliver the highest quality sound I can from my iMac. I use optical cables with my other peripherals yet I was unaware that there was a converter that could take an optical signal to an analog "headphone" jack? This doesn't reduce the quality at all? Could someone tell me the exact name of such a converter and if I'm correct in assuming it allows a standard optical fiber audio cable to fit in the "headphone" jack on my iMac - would be much appreciated Would like to run out and grab one And again, is this the best option for highest quality audio from my iMac?
