As has been discussed almost endlessly here and elsewhere, fault lies with HDTracks only in the sense that they are not posting detailed spectrographs of their offerings. The fault (as usual these days) lies with the labels and what they give to HDTracks. There are a lot of very well mastered (and good sounding) albums at HDTracks, and there are a lot that aren't. The vast majority of their "hires" offerings sound as good or better than any other digital source from the USA (I'm specifically excluding things like the Rolling Stones SHM-SACD's of their post-ABKCO albums).
