Here’s another feedback today from Fiio X5iii customer in South Korea. He said Fidelizer Advanced ROM can be expressed in three words as below.
It can be expressed in three words.
absolute
Perfect
beautifulThank yous !!!!!!!
I’m happy to know that Fidelizer Advanced ROM makes Fiio X5iii absolute, perfect, and beautiful listening experience. 🙂

5. Open X7 Firmware Upgrade Tool.exe and flash ROM according to instructions provided in Instructions of How to Use the X7 Firwmare Upgrade Tool.pdf
There’s a lot of improvements for Advanced ROM and I also added Enhanced ROM into collection too. Please read Portable Products for more details including Fiio X5iii Fidelizer Mod project with 3 modification levels. Happy listening. 🙂
For new users, please read about PerfectDynamics Sound Optimizations first for new improvements with Fidelizer ROMs.
Before introducing PerfectDynamics update, I tested PerfectDynamics Sound Optimizations with iBasso DX200, Fiio X5iii and iBasso DX90 to confirm my theory. However, launching new ROM updates requires more testing and I found some issues to work on since last week.
When I left X5iii playing with repeat, I found it stopped playing after few tracks. I also added other optimizations for Fiio itself too so finding which tweaks caused this issue took me a lot longer than I expected and now it’s finally fixed and stable for whole night music.
-Based on firmware version 1.1.8
-Deodexed
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-build.prop tweaks for better video and storage performance and improve battery life
-bundled audio effects removed but keep main engine (Poweramp works now)

For Fidelizer Enhanced / Advanced ROM users, you’ll also receive the following improvements with new update as below:
-Added PerfectDynamics Sound Optimizations for more accurate sound reproduction
-Added second micro SD card slot support (experimental)
-Disabled Kernel Same-page Merging feature
-Fixed playback instability with high capacity micro SD cards
-Optimized I/O priority for better stability

Dear all Fidelizer ROM users out there who’s enjoying music with better performance. Today I’d like to make an announcement, a big ones. We reached a new level of sound quality improvements with ROM optimizations today.
Back in the days ROM optimizations was heavily focused on DX90 unit and it happens to sound fine with smartphones too so I have DX90 as a reference unit and others seemed to be working fine to some extent.
After focus shifted to DX200, I spent a great length of time and effort to make optimal sonic performance with every firmware change. Sound signature changed with almost every new update according to what my friends and clients told me.
And one day, I tried flashing new DX90 ROM with recent changes from DX200 and I noticed that something went wrong after listening to newly flashed firmware. I realized it’s time to took seriously as I did with Fidelizer software.
As you may know already that each device has different hardware with different RAM size, different processor architecture or number of cores working. So there’s no specific value for every hardware unit to reach its peak of optimizations.
PerfectDynamics is newly added optimizations based on concept of exact optimal spot for each hardware. If you want to get the best for specific device, it will involve a lot of time and effort to reach that goal.
I’ve been working on this PerfectDynamics project for over 6 months already. I started from sending DX200 ROM updates with different changes and flavor and receive opinions from clients like I did with DX90 years ago.
The key to get ideal transient attack, optimal scale of dynamics and best transparency and imaging is to minimize the effect of OS jitter from system and kernel parameters that are also depend on hardware too.
Some customers told me it has good dynamics and very musical but some also said its depth and imaging is a bit behind SP1000. Next revision has better depth and seperation but lose some energy in dynamics.
I keep working on this DX200 ROM updates for a long while again and again until I get full sound dynamics, intense transient attack, smooth and linear sound, with most transparent imaging for deepest depth revealing every micro-detail.
After long repetitive research and development, PerfectDynamics is the answer. It works like you hire professional display calibrator who’s really good at this to bring the life and soul of movies with the most accurate and faithful tweaks.
However, it’s not just DX200 unit for me to take this long. After finishing DX200 unit, I need to work on Fiio X5iii and DX90 to get the similar result with different hardware and RAM size, ideal devices for my research.
So I’ve finished my research with PerfectDynamics capable of applying this new improvements for all devices. That’s why today is a big important day for such thing like this being possible for every device I can work on.
PerfectDynamics is specific device optimizations so it won’t be available for Purist ROM which contains only generic tweaks that I can put on without testing. Advanced ROM will also have optimizations for PerfectDynamics sound applied more than Enhanced ROM.
Since PerfectDynamics will involve updating all kinds of ROMs for every device, right now only Fiio X7ii and iBasso DX200 has PerfectDynamics sound optimizations applied. I’ll publish PerfectDynamics for Fiio X5iii with 1.1.8 ROM next.
If you’re a believer of bits are bits topology, it’s OK. At least there’s Fidelizer Purist ROM that you can enjoy smoother ROM with some goodies for free. 🙂
Here’s another feedback today from iBasso DX200 customer in Thailand. He shared his public feedback in forums and also share me his private feedback to some people as below.
I modified both device and Amp module (which has soft mute circuit bypassed for better sound than not to)
I can say that this one can go up all the way in the same level as SP1000cu/ss only that the house sound is not the same character.
SP1000 both version sound more edgy and meatier than my mod DX200 which makes vocal sound more like a real person in some recording but it make some song sound weird and SP1000 both version is better in layering in depth axis but not much better. Other than that, DX200 with Fidelizer Ultimate Mod is equal to both SP1000 and beat them in some category.
Modded DX200 has wider soundstage, more reference sound and also more musical than before modding. You’ll feel how the recordings were recorded for real! Something that was hidden when I use original DX200 was showed in great layering even the sound character will not render the sound layering more obvious like SP1000 do but you will be surprised by how it can be improved. Whispering sound in background of recording becoming more obvious to recognize without volume up. The echo of the vocal and instrument is more real.
I intended to do only Amp1 modification but when I hear DX200 with Fidelizer ultimate mod, I changed my mind. After I heard what the one that he by-passed the soft mute circuit, it sounded even better that I sent back my unit to do it too.
If you are good to go and have some effort to wait for it, I suggest you to send your unit for ultimate modification. But you can try only Amp module modification first to make sure that his stuff is real deal.
If you need a suggestion, try his paid firmware modification first. It’s cheaper way to hear the difference and you can always get the update when newer version fw is out.
For more information and the price, contact him directly. Hope this helps. 🙂
I’m also working on new optimizations in Fidelizer ROMs based on feedback from DX200 Ultimate Mod users too. 🙂
