Fidelizer 7.9 released – Improved compatibility with AudiophileOptimizer and Windows XP

After releasing version 7.8, Fidelizer’s compatibility with Audiophile Optimizer’s default shell feature is improved a lot. However the solution isn’t 100% fixed yet so this version will resolve the remaining cases.

I also fixed Windows XP issues on some cases and added Steam/Origin compatibility to resolve slow down issues for some customers who didn’t set Steam/Origin as music player application.

My birthday is coming up soon and I hope to make public announcement about this update on my birthday. I’m busy with Portable Products section to add more devices with approval from them right now.

Fidelizer Plus/Pro users should be received a mail about update and download link by now. If you somehow didn’t receive an update notification as I received some delivery failure message too, please contact me for an update with your customer data to verify.

Since we have over 2,400 licenses now so we can’t deliver all licenses in a single day with 1,000 sending limit per day. We made some changes to delivery platform to slowly send software update to customers. I also noticed some customers have yet to provide fidelizer.key data after asking a few times so please contact me back.

Added DX200 with Fidelizer Ultimate Mod in Portable Products

DX200 - Fidelizer Ultimate Mod

 

After launching Portable Products section for a while, I received some inquiries about DX200 Fidelizer Mod. However, all customers who committed to DX200 Fidelizer Mod ended up ordering whole DX200 unit with Ultimate mod instead.

So I added DX200 Ultimate Mod option for audiophiles who want to pursue the ultimate sound quality improvement. It comes with the following features:

 

-Fidelizer Advanced ROM
-Over 30 of capacitors upgraded with highest grade of tantalum capacitor
-Clock modules are upgraded high quality ones from Japan for processor and XMOS interface
-Re-designed op-amp implementation in AMP module with completely different set of 6 opamps
-Soft-mute circuit by-pass for purist signal transmission in AMP module
-Power capacitor in AMP module upgraded from 2x470uF to 1,000uF capacitor
-Some tweaks for power supply and internal damping in main unit

Price: 1,800 USD

 

This is truly my masterpiece for DAP modification. It’s the only DAP that can bring true desktop contender performance.

The reason why I received only DX200 Ultimate mod instead of AMP1 is probably from massive sound quality improvement and recommendation to friends. I’m also having another two DX200 units waiting to apply Fidelizer Ultimate Mod too right now.

I also have other DAPs like AK380, HM901S and Plenue waiting for modification too so if you’re interested in modding your DAP, feel free to drop me a message and happy listening. 🙂

Added DX200 Advanced ROM feedback from Mavwong

Here’s a new feedback today from iBasso DX200 customer. He uses DX200’s as digital transport to his car sound system with great results.

Hi Keetakawee,
Just install it yesterday. Good job! it’s much much better with your optimized rom on top of already great sounding DX200. I find that the mango app sound more clean and focus compare to appolo app which sounded more meaty but focus is not as good as mango app.

I mainly use in car using the optical output and my car sound system never sounded this good before, ever.

it’s sure worth USD99 even though if could be cheaper as many consumer not as easy as me. I also bought your pc fiderlizer pro previously as well.

Here’s the first feedback from a customer who uses DAP for pure digital transport with Fidelizer Advanced ROM. 🙂

Fidelizer Purist ROM featured in Positive Feedback’s Fiio X5iii review by Tom Gibbs

Last month, I talked to Mr. Tom Gibbs about his new home and listening environment. He mentioned about reviewing Fiio X5iii so I sent him my Purist ROM that I was working on at that time for him to try hoping he’ll enjoy the music while preparing a new room.

Today he sent me his finished review about X5iii and he also talked about how Fidelizer came to the rescue as below.

 

Fidelizer to the rescue!!

I let the X5 burn in for a while by playing on repeat for a couple of days before doing any serious listening; I honestly believe the sound quality of both the X5 and the accompanying F5 headphones improved significantly with about 50-100 hours of play time. I also did a couple of firmware updates to the system; at this point, I started to feel as though something had gone quite wrong with the overall sound quality of the system. In an email exchange with Keetakawee Punpeng of Fidelizer, we were talking about how things were going for me in my new home and new listening environment, and I happened to mention that I had the X5 Gen III in house and under review. He immediately emailed me a link to a firmware modification he developed in cooperation with Fiio; apparently, many had complained about the sound quality of the F5 after performing updates. He started checking all this out, and found that an earlier iteration of the F5 Gen III sounded significantly better prior to all the updates. He then developed an installer program with his contacts at Fiio that would update the operational aspects of the upgrade, but would also roll the pertinent aspects of the sound quality back to the best iteration.

The install was just a tad tricky (not unlike most anything with any of the DAPs I’ve had recent experience with), but I have to admit: the great sound was once again back! Now, when the X5 opens for the first time, a Fidelizer splash screen appears prior to the usual Android stuff. What a really strange coincidence, how this all worked out, and my hat is off to Keetakawee and Fidelizer for helping fix what should have never been monkeyed with in the first place! He also tells me that he can make additional modifications to the X5 Gen III that will lift it into the same level of performance as some AK units; you can get more information about those services HERE.

 

It’s great to know how $399.95 DAP packed with all kinds of features can do from a professional reviewer. You can read his full review to see how it truly is the best bang of the buck especially with Fidelizer ROM.

Fiio X5iii is the DAP with most potentials for improvements in my opinion. As I already explained in Portable Products section, Fiio X5iii Ultimate mod version costs only $899.95 with very close performance to flagship devices out there. 🙂

Some people asked for Apollo app in Fidelizer ROM so here it is.

I shared my mods of Apollo app XDA forum with the following changes:

 

-Compiled with Linaro 4.7 Toolchain with Fidelity Edition flags optimization (-O3/Strict-aliasing/etc.)
-Raised the handler thread priority level to high priority audio level. Normally it was set to background level but if you want to turn this to music phone, that level of priority won’t make sure you’ll get good music without being interrupted.
-Increase performance on caching system. It may consume little more space but should improving disk caching performance significantly. I decreased load factor from 0.75 to 0.5 so it shouldn’t consume much more space like 0.25 (Or maybe I should)
-Reduced buffer size and output latency in disk caching. This should some what improve performance for low latency audio playback.
