It also assumes that the transfer of bits from CD to hard disc was perfect, i.e. bit for bit and error corrected and that the reading of the data from the hard-drive is perfect. These are much better assumptions than assuming that your CDP reads every bit perfectly every time. Back to the original question, the lower the jitter that is sent to the DAC, the less jitter out of the DAC. The more jitter-free the transport, the lower the overall jitter in the signal passed to the pre-amp. Is it audible? Only you will know. Some say yes, some say no.
