Here are my 24-bit/HiRes albums. I did not filter them by genre, because I think about 80% of them are Metal. Metal, especially Death, Thrash, Black with all subgenres is also the music I hear most often.
The song that just happens to be played in roon, I’ll give as a recommendation. I would have a lot more, but for now.
For me, it makes a difference whether I hear an album “only” in CD quality or in a higher resolution. Of course, this mainly applies to newer recordings that have already been taken at a higher resolution. Older recordings (which may even have been upsampled) can of course argue about whether it makes sense. For me personally, it sometimes comes down to the feeling of having the best possible quality. Of course there are also albums, the CD quality sounds better than the HiRes or remastered version. This is a very subjective thing and everyone has to decide for themselves.
Incidentally, I would recommend http://www.metal-fi.com.
