PerfectDynamics 2.0 Sound Optimizations will be introduced in Munich 2018 AV Show

 

Fidelizer - PerfectDynamics Sound Optimizations

 

PerfectDynamics technology is device-specific optimizations for Enhanced / Advanced ROM introduced on 1st October 2017. In upcoming Munich 2018 AV Show, I’ll introduce PerfectDynamics 2.0 with iBasso DX200 and Fiio X5iii device.

During development of PerfectDynamics’ initial version, iBasso DX200 and Fiio X5iii didn’t get the better sounding version of firmware and they later improved in over time. After I tried DX150 2.9 firmware port on DX200, I feel it’s ready to take this to the next level.

Having good sounding firmware to optimize is very important because sometimes you can’t be sure whether this optimization will really improve over all performance or just compesate the flaw with firmware itself. Even now I’m still not sure that I can finish it before the show lol.

 

PerfectDynamics 2.0 Goals:

-Fix random crash and reboot in some scenarios (90% – Fixed stability issues with boot image optimizations)
-Decay, depth and imaging will be important than clarity and separation (60% – Tuning I/O optimizations)
-Transient dynamics will have improved linearity which will also reduce digital glare effect (40% – Tuning PerfectDynamics specific optimizations)
-Full sound reproduction will take higher priority than making audio sounding pure (40% – Tuning audio optimizations)

 

If I can archive all that, PerfectDynamics 2.0 will make Linux based audio performance becoming closer to Fidelizer’s optimizations in Windows. I’ll start working today on iBasso DX200 first and I hope to master PerfectDynamics 2.0 before the show. 🙂

Introducing PerfectDynamics sound optimizations update for Fidelizer Enhanced and Advanced ROM

 

Fidelizer - PerfectDynamics Sound Optimizations

 

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.

 

iBasso DX100 to DX200 changes

 

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.

 

Portable Products

 

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. 🙂
