Here’s a new feedback today from a customer who purchased iBasso AMP8/AMP9 with Fidelizer Signature Mod before went later completed Masterpiece Mod with DX220 main body modification.

I don’t know about the advanced rom but fidelizer did a remarkable job modding the amp9. The level of depth
I get is beyond what I have ever experienced going even deeper than n8. This is organic to dripping max,
not to mention sounding so vivid and realistic. Feel like I finally got the sound I deserve! The fidelizer
guy must have been smoking something real potent while he was cooking my amp9 tube circuit.
Hope this wasn’t coincidental. 🙂

He also purchased a new iBasso DX220 DAP with main body mod instead instead of sending back unit to apply modification so he could compare stock and modified unit side by side. 🙂
