64 bit floating point volume control with DSD

Hmmm, you should probably not make assumptions on hardware you have not evaluated nor about the reasons behind the decision to not support volume control. Did you even read the thread the post you responded to had referenced? If you had, you would have read this response:

@Brian directly states that one of the main concerns is that the endpoints ( not server) potentially not having the horsepower to do the processing. In addition, brian states:

[quote=“Brian”]It would also be distasteful to have a signal path that re-modulates
the DSD twice–once to process it in the core, and again to process it
in the endpoint later.

So no, we don’t do it. Too many compromises to make it a good feature.[/quote]
