In my view the DAC+ DSP is a completely different animal to the straightforward DAC. The DSP variant has considerable functionality that is not present on the DAC. The DAC+ DSP board should, therefore, have its own category in the forum and not be lumped in with the DAC+ posts.
Clearly the DSP functionality has massive potential and deserves a dedicated Forum folder/WiKi etc. At the moment info is spread all over the place; HiFiBerry Forum, Github, Analogue devices Forum....and its quite a pain for a newbie to really understand what the DSP can do and how to do it. A 'one-stop-shop' forum which provides all the necessary info or links to it would help everybody. I see incredible potential for this device.
