Best thing would be to call me at 563-528-0884 as your answer is long.
First off, over sampling is only part of what makes a difference and is not the most important part but to answer your question...
Oversampling is the CD players way of comparing multiple snap shots of the same frame of music and matching the best picture with the original.
If an engineer knows how to design a digital section, oversampling can be a bad thing as it pulls down the power supply and slows down the DAC's.
Bitstream is a constant flow of 1 bit at a time so it is technically a DAC with 255 times over sampling. Only advantage of this is that it can make cheap players sound better.
The advantages of SACD are more related to the fact that the recording proccess drops from 9 stages to 2 and the fact that it gets rid of the need for water marking or copy protection which hurts sound. Again, the main advantage is that it makes good sounding digital more affordable. A killer CD player sounds better than most SACD players.
Maybe others can do a better job than I of explaining things.
