...by using 4 bit or 8 bit DSD (which some will argue IS pcm, so you have some support). Point is, IIRC it is built into some of the newer "all-in-one" chips which don't require going out of dsd mode for bass managment. This same approach is used professionally in most recent version of the SACD workstations.

First of all "DSD" is a marketing term, and not a technical term. It was defined by the marketing gurus at Sony. And what they defined "DSD" as is one-bit digital audio at a sample rate of 64 Fs.Now you *cannot* do *anything* to this signal, even change the volume, without changing it to more than one bit. Then it is, by definition, no longer "DSD".
The marketing gurus from Sony painted themselves into a corner. They claimed all kinds of sonic miracles from "DSD" precisely *because* it was just one-bit.
But they can't have it both ways! If it is so wonderful because it is one-bit (as those who drink the Kool-Aid insist), then the very act of converting it to multi-bit (ie, PCM) must *by definition* destroy the wonderfulness of "DSD".
On the other hand, if converting "DSD" to PCM somehow does *not* destroy it's alleged sonic wonderfulness, then why bother with "DSD" at all? Why not just use PCM?
