My main objective was to find out why people prefer cd players over a computer/dac combo.I'm surprised that as far as I can see no one has yet mentioned the jitter issues that can arise with interfaces between dacs and spdif or aes/ebu or usb outputs, but which do not arise with a competently designed one-box player.
Certainly those issues can be and frequently are overcome, but not without some combination of luck; trial and error; careful selection of components, jitter rejection technology, cables, connector types, and even cable length; and in many cases added expense as well.
Obviously there are many other factors which will result in a one-box approach not being the right solution for many people, but the jitter issue would certainly seem like something that should be a significant consideration in the tradeoffs.
