Onkyo HF Player Ver.2.0.0 has added a new function which calls “Real time DSD convert” function. It converts PCM (WAV, FLAC, ALAC, e.t.c.) high & normal resolution audio files to DSD high res audio signals.
This function provides for Japanese users only. But you can use this by changing language configuration of iOS temporally. Onkyo hides the button of “Real time DSD convert” from HF player’s Settings screen. I don’t know the reason why.
I explain the way to activate “Real time DSD convert” function for non-Japanese users.
