I was thinking about buying an Astell & Kern AK120 for quite a while. As an alternative, I want to try the Onkyo HF Player for my iPhone 5S. I was wondering if the actual output is really 24-bit/192 kHz or that the hardware DAC automatically reduces it to 16-bit/48 kHz.
I know iOS 8 is coming with HD Audio support, but I wonder if the iPhone 5S's Cirrus Logic DAC can truly output 24-bit or that they read 24-bit and convert it to 16-bit. If the Onkyo HF Player really outputs 24-bit on the iPhone 5S, I want to buy it. Any thoughts on this?
I checked the app information of the Onkyo HF Player in the Apple Store. Apparently, HD-audio is downsampled through the headphone out.
