do yourself a favor and get a jitter remover device and hook this up wih a good toslink cable with the mini adapter (sold at fry's for $2) from your imac. then use the best coax digital cable you can afford to hook this jitter device to your external dac. i was impressed when i 1st went from the imac into a dac, but there was a huge jump when i inserted the jitter device between the computer and the dac.
