DSD players for iPhone

Just switched to the USD10 Onkyo HF Player from the free VOX after using VOX for many years. Very easy to load music into it from iCloud Drive. Also drives my Beam 2SE lighting DAC in DSD over DOP, whereas VOX would convert DSD to PCM. Great fun just to see the DSD light come on finally. I tried HF Player many years ago, but the interface then was not good. If you have any Onkyo or Pioneer receiver, you can get it for free.
