Smashing! I can test this out now with available digital sources that I have, sounds like actaully I can take Node out of a cellar, not that it’s gonna bring much difference though, though, but… 
OK. CD part is very clear - USBStreamer B scenario would work for any CD transport. I also assume via optical it would handle other PCM rates, which would require manual switching in HQP.
I wonder, is there a “real time” SACD solution ? Would HiFiBerry Digi+ I/O hat as suggested by @Stefano_Antonelli work for SACD transport streaming?
Also I understand that there’s multichannel challenge, for now I’m exploring 2ch playback options.
Open to any ideas.

In my library I have a collection of digital rips including CD’s, DVDA’s, LP’s and few hundreds of SACD’s. The recent progress in digital HiRes streaming is immense and there are a lot of music out there. However more often than not I strat catching me thinking that true art aspect of some recordings is being totally lost by increasingly non-stop AI playlists clulture or approach. There are albums that are incredible pieces of work from the content, mucisal, poetic and recording perspective. So more and more I miss this ritual, of having an album, putting it in, enjoying every detail of it, and when it stops, having just WOW and silence… Can I do the same vith digitized source, certanly yes, but I think the large part of art concept is missing. In the same line of thinking I’m looking at this or similar: TN-400BT-X | OVERVIEW | TEAC | International Website I’m not interested in bying hundreds of LP’s, but there are some gems out there…
