Sacd; dsd64 or dsd128 audio quaity!?


There is one thing it had goes on my mind the latest days; and it is this:

Is really the quality of dsd128 better than the same file in dsd64 or in a sacd disc?

And for those of low budged (poor poeple) what do you recomend:

To buy a cheap dsd dac or a bluray that plays sacd in the same price?

Had someone compare a sacd disc whit the same remastering in dsd128?
