Even if there was no commercial DSD available, many people would still use HQPlayer (or other software) to upsample everything to DSD anyway. The reason there are DSD-only DACs is not because of commercially available DSD recordings, but because of software upsampling. Many are reporting huge SQ improvements by sending DSD512 to their DACs instead of DSD256. I don't own any DSD but much of my listening is to DSD, upsampled via HQPlayer. Sounds Mahhhvalous.
Disregarding DSD for a second, others have great success upsampling to the same rate that their DACs upsample to anyway (8x or 16x redbook), bypassing the internal upsampling that the DAC chip does (in most cases) and performing this process in software on a powerful PC.
In either case, I like having the ability to explore these options, as they make significant SQ differences.
Or, one can trust that the one choice that the DAC mfgr picked just happens to be the one that you would have picked, for you room, system, musical taste, etc.
I just hooked Digital Amp Tommy up with a Pi running PiCorePlayer - The SQ is vastly improved relative to the SB Touch, for about 1/3 the cost.
