So I have a 24" Aluminum iMac. I know the headphone jack has optical output but I was wondering if I should purchase an external sound card like the Creative Xmod for better audio quality. I'm pretty sure that I don't need to purchase any equipment for transmitting audio to speakers, since the signal would be via optical cable, but is there an analog amp or DAC chip for headphones and other non digital equipment? I primarily use my headphones (I have the Ultimate Ears Superfi 5 Pro) for listening.
