As an audio engineer, regional audio brand distributor, DSD is a hot topic again since DSD files download relaunch the popularity of the format. This paper is highly recommended for anyone who is interested about the format.

Grimm Audio – “In recent years the DSD audio format of SACD has seen a big revival in the form of high res downloads. We noticed there’s a lot of confusion about the 1 bit DSD format. Debates about the virtues of ‘128fs’ and ‘256fs’ DSD often lack background knowledge of what is really going on inside the AD and DA converters.
