DSD. A new drug – no, but a new “can't‐be‐without‐it‐anymore” audio format bursting into our listening rooms. Direct Stream Digital (DSD) actually has been around for a while already, but it has been so married to a physical media, SACD, that it has yet to receive the attention from audiophiles that it deserves. It is only recently with the growing interest in downloading high resolution audio via the internet that DSD surged to the surface of news coverage. What were compelling reasons to use this encoding scheme for SACD over 10 years ago are now becoming convenient truths for the new era of high resolution internet audio. This paper explains the background and nature of DSD and what might happen to it in the near future.
This is the first paragraph from a white paper, called: DSD, the new addiction, by Andreas Koch.
