Sorry for my language first but let me to clarify the situation. This also applies to the DP-X1.
Both players has one or two es9018k2m DAC's and that's it.
The difference in sound due to different software sound paths.The android has a several ways to output audio and all of them have different limitations.
1) AudioTrack. Almost all applications use this method. The method is limited to 48000/16 bit or even 44100/16 + oversampling.
2) OpenSL ES - Some applications allow you to switch to this method, but it does not give advantages in the Pioneer/Onkyo too.
3) Compress Offload (ALSA) - Only native apps (Pioneer and Onkyo Music) and Poweramp Alpha It seems to use this mode. But poveramp not properly activate this mode on Onkyo/Pioneer and it does not work (yet). The method takes full advantage of the DAC and is not affected by resampling and other restrictions. This is a direct method of interaction with the DAC kernel module.
Therefore, a rule - if you want to listen to music in high quality, without resampling, use only native apps and Poweramp (later, maybe). Everything else (at least I have not found other applications) degrades the sound. To check which interface and the frequency / bitdepth with which sound is output, I used logcat.
I Think I understand why I have breath, parasite at Down Volume (1/160)....
Only the Application of Pionneer Use DAC Hardware.....
All Sofware Use Snapdragon SOfware as PowerAmp..... xD
Sound is the better with the Application by default....
I tested PowerAmp Beta 3 and I can choice "Audio Track" or "OpenSL ES", Hi-res don't Works...
I think because DXP-100r is too young, just wait futur compatibility for to have Sound Hardware DAC with other Player.....
