To reiterate: There are only two things that can affect the transmission of digital data; missing data, or timing issues involving the data, AKA the Dreaded Boogeyman and unlimited source of audiophile consternation, ***Jitter.*** There are no other magic or non-scientific factors that affect transmission of digital signal.
It's easy to copy your CDs bit-perfect to your computer; iTunes does that well. It is also easy to get each and every bit out of your computer; iTunes does that well, too.
The only remaining factor is how well your DAC deals with variances in timing of the data from the original signal. Most well-designed modern DACs do this very well. Look in particular at regular DACs with top sample rate conversion schemes for dealing with jitter, like the fine Benchmark DAC1s (see Stereophile's test of that unit for how well it rejected scary amounts of jitter to extremely low levels) or Apogee Mini-DAC, or asynchronous units from Wavelength or Ayre (real engineers). Finally, there are som well designed devices from Empirical Audio (real engineer) that will apparently reduce jitter in the bit-perfect output from most computers, if you feel the need to go over the top.
There will be all types of h-h-harrumping, more or less expert (frequently less) personages who will take all manner of umbrage to these heretical statements. Some of these same folks will also try to sell you magic clocks and make all types of incredible allegations of little things they do to their computers that improved the sound according to that heavily biased and easily influenced arbiter of sound, the Human Ear. Be amused, but also remember that if the long-distance, and indeed worldwide and through vast distances in space, transmission of digital data was not a very well undestood and largely a solved problem, then the world would come to a screeching halt. And the examples cited include far more jitter-critical applications than the transmission the the few, sad, old bits needed for 16/44.1 audio.
PS: I don't own anything from the above cited sources.
