I have an apple MacBook pro of late 2008, it has a combination analog/optical output. I am using it now as optical connected to the digital input of a very high quality home theater preamp/processor. What I need to know is if the digital output from this port is a bit perfect digital representation of the audio I will be playing or how I can ensure the purity of this signal. Or if it would be better to use the USB port and connect to a DAC and then to the home theater. I want to have the purest digital signal from the computer and bypass any sound processing, mixing or alteration inside the pc.
