I found the following Audiostream interview with Mr. T. Of special interest was the following;
"If we convert from 24-Bit at 352.8kHz (DXD-PCM) to 1-bit at 2.822MHz (DSD) - we need to throw away around 99.96% of the amplitude information the PCM format is capable of, while we are only having 12.5% of the time domain information that the DSD system is capable of. If we convert to DSD from DXD, that is 1-bit at 2.822MHz to 24-Bit at 352.8kHz - we need to throw away 87.5% of the time domain information of DSD, though we can theoretically remap all of this into the amplitude domain. So in effect we get the worst of both formats, rather than the best of one."
Maybe higher rate DSD would even things some, but I find it interesting. Also very few albums for sale at 352kHz. I would bet Sony thinks they can remap into the amplitude domain, or they wouldn't have put it forward as an archival format, but then again maybe they would. I have read on a forum for recording engineers where they say DSD was meant to be converted to PCM, but PCM was not meant to be converted to DSD. They certainly seem to do it though.

Big speakers and little amps blew my mind!
