I'm very confused with iOS device DoP output.
I've purchased the full version of Onkyo HF Player so that I can play Hi-res audio including DSD files now.
Everyone says that in order to output the 24bit/192KHz PCM or DSD to a external DAC, a CCK is required.
But I noticed that almost (I'm not sure about this) every one of the DACs you were mentioned above, was not a iOS compatible device (the Herus for exaple), so these DACs could not receive any kind of digital audio format from iOS devices by simply using the 30pin to USB or Lightning to USB cable.
Now I've owned a Sony PHA-2, which is compatible with iOS Device digital audio output through 30pin to USB and Lightning to USB cable. PHA-2 can decode the so called Hi-Res audio which up to 192KHz/24bit and DSD stream.
I set Onkyo HF Player and PHA-2 like this:
iPod Touch is connected to USB-A shape digital-in jack, which is claimed to be used by Apple devices.
DSD files can be recognized by app and output through PHA-2, but I noticed that the description of HF Player on App Store said :
When playing back DoP, the equalizer and cross fade will be disabled. Also the frequency response will not be displayed
On my device, when the DoP playback has been enabled, the cross fade will be bypassed, and the volume can not be adjust in the app, but the equalizer and frequency response are still can be enabled and become effective.
Is this means the Lightning to USB dock cannot output DoP correctly? Or PHA-2 cannot decode DSD through iOS device USB input jack? Or in fact the DoP output works fine? Since PHA-2 has no any indicator to show the state of the inputting format.
If DoP cannot simply work with normal Lightning to USB cable, will CCK work with iPod Touch Gen5 and PHA-2? (iPod Touch>CCK>USB-A to microUSB cable>PHA-2 PC USB jack)
BTW, driver is required to be installed under Windows OS so that PHA-2 can use ASIO and Kernel Stream to transfer DSD bit-stream. No driver is required under MacOS, because the only way to output DSD format audio under MacOS is DoP, not the native DSD bit-stream.
