Someone told me there was a nice article from the CTO on how this is done. I cannot find it. Does anyone have the link?

There are a few, but this one is pretty good.

Parametric EQ and DSD playback

We do indeed process DSD without performing a DSD->PCM conversion first. The signal path is reflecting that accurately. I’m going to explain how it works–keep in mind that there are some subtle technical details here, and some background knowledge is required to understand them fully. Processing DSD isn’t nearly as straightforward as processing PCM. With the exception of a few simple operations, you can’t process it directly in the 1-bit representation. There are more steps involved, but it’s p…

Wooosh… sound of it wizzing by me. I will have to read again and digest, but I wanted to thank you for that post.
