my 2 cents after with 5 years with the MSB Select II and the Extreme, now 6 months with the Wadax combo, is that both pcm and dsd are awesome, and if you have a strong preference then you have not yet heard them both 'right'. at the top of the digital hardware food chain there is really not that much to choose between them. not claiming there is no difference, but unless you isolate completely native recordings in one or the other format then compare....what are you actually comparing? mostly with dsd it's PCM sourced files converted to dsd. they are 1 and 1a. and only the more flexible work tools make pcm a bit more usable, so lots more music is made with it. dsd files are smaller.
OTOH many dacs do favor one or the other, or maybe filter settings can do that, or server settings. what is causing what outcome? takes some homework to sort that out.
