DSP has a lot of possibilities in improving sound reproduction and there was in the 90s an early start to implement it. But 1999 the SACD got introduced and as DSD is incompatible with DSP, DSP was at least in consumer electronics disappearing. Then the SACD dwindled away and DSP reappeared. Devialet's ADH is DSP based and therefore can not be done in DSD. DSP is also required for digital cross-overs (I am using that function of my D250 but also now frequently used in active speakers like the Phantom), speaker correction (SAM) or room corrections. Most DACs convert DSD anyhow to PCM but there are also some which do the reverse (or back and forth like the new version of PSaudio). Of course it would be good that Devialet can use DSD files but I see it as last years fad. Not that there are good DSD recordings (many are only converted PCM files) but I think the restrictions of the DSD require a simpler and therefore purer recording process.
