Version 2.3.125 is now ready. It took me a while to work on couple of new optimizations and some caused strange bugs causing me a few days to fix it along with my DX200 brick incident. I personally find 2.3 working smoother than before unlike feedback in Head-Fi. Maybe my optimizations is more compatible with 2.3 improvements.
Changes on this update
-Re-based on 2.3.125 firmware - I must admit this makes DX200 sounding so much better. It makes me reflected upon some tweaks I put on Advanced ROM to correct it with more revealing synergy improvements.
-Modified power.rk3368.so to shutdown 7 unused cores on 2.3.125 binary file - Since I really like this 2.3 sound, I don't want to replace power.rk3368.so file from older version so you get better battery life with 2.3.125 power management improvements
Changes on Advanced ROM
-Added ART architecture features optimizations - Default configuration use kind of generic ART features so I changed to matching chipset used in DX200 for full features utilization.
-Improved Android files optimizations - I'm taking this to further level with improved image optimizations for lower file size and smaller footprints.
-Re-calibrated I/O priority optimizations on boot image - After upgrading to Advanced ROM, I noticed something was missing from public Purist ROM and I corrected this issue in boot image optimizations.
-Launcher is now back to optimized stock - Due to custom launcher not meeting up expectations and also caused some strange issues in X5iii branch, I decided to revert back to optimized stock launcher for better performance.

The improvement with Purist 2.3 is very satisfying. I could live without modifying hardware for this 2.3 upgrade. Thank you so much iBasso for major sound quality improvements. Advanced ROM users may request for 2.3 update file and I'll send accordingly.
