Why is digital audio so complicated? Where did it all go wrong?
#20
Krisp suggested it to be error free from source to DAC OUTput. I'm saying it is at best error free up to the D to A conversion. And with error free I mean bit perfect while we're in the digital domain.

The bitstream signal representing the "ones and zero's" is an analog signal. With it travels noise. The signal also distorts while "in travel". The noise and distortion influences the D to A process. Noise, for example in the ground plane, also influences clocks inside the DAC, causing jitter.

Of course no one can explain it all in just a few sentences and I'm retiring from this topic. I have to be honest and admit I don't enjoy these types of discussions. The language is a bit of a barrier for me too. Also I'm enjoying listening to my system now and typing on an iPad which is not ideal. Going back to fully passive mode now! Wink

John Swenson is one of the gifted men who has written plenty or articles on these matters, so I'll just refer to those as a nice starting point. Of course lots more can be found on the net.
