I suspect both are right in their own ways.
Both PCM and DSD represents different ways of interpreting and processing the data, each with their own unique shortcomings.
If you can fix those shortcomings of one way, it'd seem that that approach is better. Something like saying everything looks like a nail when all you have is a hammer
That said, I find myself in agreement more with the DSD camp that companies like dCS EMM and Playback subscribe to.
