The difference you are hearing is the higher quality of the external DAC versus the one in the Oppo. What you have not yet experienced is how good the DAC2 really is. Feed it a really low jitter digital signal and you will experience this as well. The ATV and the Oppo are not going to cut-it. They will ultimately hold-back the DAC2.
