Do hi-res files sound better than Redbook when converted to DSD?

[jamesg11]

Well, the standard view would be it depended mainly on the quality of recording, DR etc ... eg on sacds, the redbook layer often has a different-inferior re-mastering cf to the dsd layer.

The key framing of the question would be comparing 2 recordings of say 16-44 & dsf64 or 24-192 that had identical recording quality.

If that were possible.
