On my EAD DSP-7000 MKII there is an error indicator that shows a "jitter" or error reading a digital data. You can hear the jitter from the good quality DAC coupled with bad quality CD-player or Transport. Usually when it there is an error occured from the digital output very often DAC's possibility to correct a huge amount of "trash" is limited and it goes on and on and on up to the end of CD. Even if there is a jitter reducer is present, it may not be enogh to eliminate it.
It sounds like a part of the sound bandwidth dissapears or becomes shallow and unrecognizable. It may be bass, midup or midlow -- any part that you actually cannot predict. At the same time, if I use an analogue output of CD-player without my DAC, everything goes more or less stable certainly with large overall audiable performance sacrifice.
You WILL NOT hear it if there is a good quality dedicated transport coupled with decent DAC, also if there is a bad quality player coupled with the bad quality DAC(with huge amount of oversampling) since the bad quality DACs aren't that sensitive to errors and designed to enhance the signal rather than linearly reproduce it.
The ideal DAC does not have any oversamplings.
These tests were made with Rega Planet CD-player in comparison with my dedicated Monarchy Audio DT40b transport.
