In the early day of release of CD, some scientific >prediction is no need for expensive CD front end for play back of CD disc. It turns out that this is an incorrect presumption. It is possible to measure a digital output and determine whether it is a perfect bit copy of the input. Such investigations show that some digital outputs are exact, and others are not. Here is an example of the performance of a system with exact digital input and output: http://www.pcavtech.com/soundcards/baseline Here is an example of the performance of a non-exact digital input but one that has high quality: http://www.pcavtech.com/soundcards/ADA1000/48-44/ Here is an example of the performance of a non-exact digital input but one that has far lower quality: http://www.pcavtech.com/soundcards/ct462044/index.htm
