Most receivers which seem as if they are doing bass management with DSD are turning it to PCM first, and then performing the filtering.

I've never seen DSP algorithms for any sort of signal processing on DSD. The only thing I know any equipment does is time alignment for speaker distances. Oh, it is also possible to do a little dynamic range expansion by increasing the size of each "step".

DSD is not a manipulation friendly format.
