For new users, please read about PerfectDynamics Sound Optimizations first for new improvements with Fidelizer ROMs.

 

I tried to update Fidelizer ROMs for these products since last month but it was very time consuming to update 3 units at the same time and there’s other stuff I need to pay attention when I was going to work on these units. iBasso DX100 is also very important to work on too.

Now I’ve finished PerfectDynamics Sound Optimizations for all existing products in website. I’m very glad that I’ve made it this far so I can start working on other DAPs like Calyx M, Onkyo DP-X1A, etc. I didn’t forget them but there’s a lot to work on including DX200 2.7 ROM update.

If you still use good old iBasso DX50/80/90, you can check out Fidelizer Purist ROM first and see. If you’d like to upgrade with PerfectDynamics Sound Optimizations in Enhanced / Advanced ROM, there’ll be a lot of improvements that won’t disappoint those who can appreciate Purist ROM. 🙂
