nice article, not brilliant though.. I had a feeling that some of their assumptions were not completely correct..

well, it wasn't everything I wanted to know... but it wasn't a bad read.

They still never did explain any mechanical theory behind why putting marker on the edge of the disc or "circumcising" the disc would make any difference, but It did satisfy me that my EAC sourced FLAC digital files are just as good as any $$$$$ cd player's digital output, and it's just my DAC that matters.

This report like many other of the kind misses the point that the audio data on a redbook CD is not organized like a groove on an LP. Data is stored in blocks and consecutive logical blocks are interleaved on the surface. In order to to give any constant stream of digital data the blocks are buffered, stripped of headers etc, and then handed to the digital output from the memory buffers in the right order. Some really strange (and very sophisiticated) engineering has to kick in to manifest a correlation between the variances in the pit and the jitter in the digital signal when the numeric value for that particular pit is transmitted.
