It is all just a "niche". Most just get their music off their phones. MP3 is all they know. Moderately priced to high end has always been just a niche but even more so today with so many cheap, awful sounding, easy options. As for converting all to DSD, that can not improve the quality of your sound. You are just moving the bits around from one place to another. Example a round bucked filled with water poured into a square bucket. No gain. Possible some loss. Definitely not improved. Native DSD, that is different animal. Possibly an improvement. I have heard some but content not to my listening interests. I will stick to HDtracks. Largest selection of HD music. Buy on the sales. Now CDs, another story. I use to buy CDs used, rip, then sell back. Some times forced to buy new, rip and sell back. Find for digital recordings, HD down loads sound the best. One reason is you take the drive out of the equation. A second is that 24 bit is quieter. A third obviously the extra info. I have compared them all. For the most part HDtracks sounds the best. Native DSD still up in the air. Have two recordings by David Elias. Sound very good. Do not have any other format recordings to compare to. Oh, I use flac not that it matters. My views anyway.
