I would strongly consider the sx and either not bother with dsd or have a dsd dac.
I anxiously awaited the release of a certain Jazz album to be available in DSD. It was recorded in 1958. There are many iterations of it, including a 24 Karat Gold plated CD that you can buy for $300, if you are lucky. Well, I have that CD, as well as the 45RPM vinyl. But you must hear the DSD release.
Best wishes,
