Apple 24 Bit 96 KhZ


With a new iMac 2.8GHz 10.5.5 OS how best to get 24 bit 96 KhZ? I have formatted the Audio Midi Setup to 96KHz 2Ch-24 bit. Can you play 2496 source music from the iTunes either through USB or Toslink/digital optical cable from the mini jack into a state of the art DAC - which is best audiophile?

Great information - I am trying to get the best audio quality possible & this is great. Anyone know an inexpensive DAC which shows the audio signal so that I can tell if its 24/96, etc.?

Bel Canto DAC does NOT accept firewire & I do not know of one.
Swhitman, can you not tell just from the size of the file if nothing else? I do recall a conversation with Bel Canto about the dac. I think I recall that it can decode up to 2$/96 but no higher.
