I'm NOT actually only talking about SACD discs. My SACD holding is less than 1 percent of my collection, and I predominantly listen to Redbook and LPs. My main playback system for digital though does utilize DSD format as the final stage, rather than PCM. I don't feel I'm confused, sorry. Perhaps I am not explaining things as well as I could, I have been building audio systems for nearly fifty years and have accumulated some knowledge and experience but I'm not an engineer nor a professional reviewer. I do understand that cds are "dying or dead," and that various non-physical formats are filling the void. It just doesn't matter to me especially as the sound is different, and in my opinion and to my tastes in my systems not in a better way. And I have more cds than I need and can still find what I want on cd (including in my own collection :)). If others listen to non-physical media, that's great.
Please PM me going forward if needed.
