Hi Keetakawee. I just want to say that I am extremely happy with your product. What made even more happy was to find the cics mode in the profile.

I believe cics project inspired many passionate computer audiophiles including myself so I’d love to address proper credits to show my respect. 🙂

Here’s another feedback today. I received his feedback after assisting him in Fidelizer Pro setup with AudiophileOptimizer 3.00.

I’ve been using Fidelizer for years on Windows 10, but the combo of 8.4 + AO3 Ultimate in shell mode is easily the best I’ve ever heard. Thank you many times!

I’m glad to hear Fidelizer 8.4 update makes significant sound quality improvements with AudiophileOptimizer 3.00 and happy listening. 🙂

Fidelizer - PerfectDynamics Sound Optimizations 2.0

 

Here’s another feedback today from customer who purchased Advanced ROM for iBasso DX120, very good neutral sound tuned without correction required.

Hello Keetakawee,

I don’t know what kind of magic you did to cook this ROM but I am now a believer. I got home an hour ago and I immediately flashed my rom to the Advanced – Purist ROM I bought for my DX120. I was blown away at how the sound has improved. I’ve been using an Ibasso IT01s with a 2.5mm balanced pure silver cable with my DX120. I thought the sound couldn’t get any better than that but it did, I am now a believer with the work you do. Keep it up! Hopefully more people will try your product. It’s definitely a purchase I am happy with. I can confidently say that me and my DX120 will spend a lot of years together. 🙂

I’m sure Advanced ROM be a great upgrade but still surprised every time I see people taking software upgrade at one third of hardware product. 🙂
