It’s been a while since last DX220 ROM release. This time they added some compatibility improvements with AMP9, DSD512 and some others. Hopefully it will help on DX150/DX200 port I’m going to bake later too. For Enhanced / Advanced ROM, I kept Google Chrome for web app now. 🙂

Added iBasso AMP9 into Fidelizer Mod products

iBasso AMP9 - Fidelizer Mod

 

Hi guys. There’s been a lot going on since last few months so I couldn’t start my investigation on AMP9 modification as soon as it’s released. I could have put AMP9 up first but I really want to make sure I tried everything and finalize with best recipe.

Now I’ve finished my research and the wait is over. Fidelizer Mod for AMP9 is now ready with the following changes below.

 

Reference – As all other amp modules, I’ll upgrade important capacitors with highest quality one,  tuned for highest transparency and fluid dynamics. Capacitors in AMP’s power supply circuit are also upgraded with highest grade tantalum capacitors.

Signature – As many people find AMP9 lacking output power, I upgraded output buffer with more powerful but also have very power efficient one. I also applied some damping materials on NuTube module to improve vibration control for better transparency.

 

I also tested battery life with stock iBasso DX220 unit listening to music at normal volume level and it lasts more than 7 hours so it won’t affect battery life significantly. You can get the best sounding amp module with more powerful upgrade in Portable Products now. 🙂

Added iBasso DX220 Advanced ROM feedback from Erwin Atmadja

Fidelizer - PerfectDynamics Sound Optimizations 2.0

 

Here’s a new feedback today from customer who purchased Advanced ROM for DX220. He shared his feedback after using free version for a while.

Apollo is quite good. It is more neutral than mango. Mango has increase booster in mid band region, focusing in vocal and the downside, it makes sound a bit muffled.

Overall your Advanced Rom improve clarity, blacker background, deeper staging. Good job.

Thanks
Regards

Apollo included in Purist ROM is a custom built version with my own code optimizations to improve sound quality. Feel free to try it and happy listening. 🙂

Here’s another feedback today from customer who purchased Advanced ROM for iBasso DX220 with AMP8 + Fidelizer Signature Mod. Now I’m back from Japan to share his story.

I have only just started to listen to this modded AMP8,and it sounds surreal. I just wanted to listen few songs for testing, ended by using 2hours! This is something, glad I took a chance with this, well paid for!!!

I’m happy to hear his modded AMP8 arrived well and working fine. I’m also thankful to his appreciation Head-Fi threads too and happy listening. 🙂
