I’m sorry.  When you convert PCM to DSD to compare the resulting DSD file to PCM you’re NOT comparing apples to apples.  Claims that the conversion process can be/is perfect are just silly.  Jitter may be the same.  But jitter isn’t everything.  This test would only mean something if the same source was originally directly recorded in both PCM and in DSD formats without intervening manipulation.  Maybe then you could compare those two direct-recorded, unconverted formats and it might mean something, although I certainly agree with Chris W. that what you hear is what you hear.

Many of you may have seen this already but I thought it interesting and important to post just the same.

PCM & DSD is a conversion to begin with in the recording process from analog microphones preamps to computers, hence zeros and one's. My point here is processing is rampant to begin with regardless of where it begins or ends, so what, if you want purity IMO play vinyl.
And where noise is concerned it starts at 40k in 2X DSD not a problem unless you're a dog!
