When I listen to some recordings/songs there is noise (white noise, pink noise ... some kind of this noise ) in background. Some songs have more noise, some has less, but interestingly some has non noise in background what so ever, perfectly clean.
It got me thinking. Is it DAC issue ?... How could it be if with some songs are perfectly fine. Than it's simply poorly recorded music played on unforgiving headphones ? (HD700 in this case)
What do you guys think about this ?
