I dunno; I see Tidal discussed on Audiophile forums a lot, in no small part because they've worked out deals to be integrated with commercial lossless/"hi res" players like Roon and Audirvana. Tidal supports both lossless streaming and MQA streaming. (MQA being a kind of weird and controversial lossy-but-high-res audio format, whose biggest difference in practice is probably using different psychoacoustic models and theoretically accounting for theoretically audible timing differences. I've listened to it on good equipment and can't say that I really hear a difference between it and lossless recording.) In any case, not even audiophiles are buying physical SACDs. There are digital downloads in DSD format, though.
