Indeed anyone can write a paper and publish it on the net. Yours is an example, of course. The difference is that Dunn et. al.'s paper is a report of a scientifically controlled study.
You say the paper is not relevant, but it strikes me that it is absolutely relevant. Your claim is basically that differences in the pit geometry of CDs affects jitter arriving at the DAC, and the Prism/DCA paper demonstrates that it does not. Based on the methodologies used in these two studies, I know which one I prefer to believe. I very much doubt that Julian Dunn was involved in the design of the Pentium 2. However, he did work for Prism, one of the foremost companies in the field of digital audio (designing their state of the art A/D and D/A converters), was a highly respected member of the AES, and was one of the leaders of the IEC team looking after the SPDIF specification. So I think he probably knew a thing or two about the subject. Sadly, he died about three years ago. -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=28621 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
