if there are coupling caps between the opamp and line-out jack.... upgrade them?

Hello,

I recently got my first DAP a XDuoo X3ii.
Great price, excellent interface especially with HibyMusic app on Android acting as a remote.
Flashed it with SinuXVR custom firmware and put a 512gb micro sd.

Despite its great price and good sound quality (for its price) I did not find any mod or upgrade for this model.
It's pretty easy to open and disassemble so I think it could be slightly improved even if there is not a lot of room to fit big caps.

I'm wondering if swapping the op amps for better one may help, I'm thinking about the Muses8820 and Muses8920 but I'm not sure if it can be a drop in replacement especially without needing adjusting the surrounding resistors.
I'll use the Line OUT 90% of the time over the Headphone out.

Thanks !

great idea! How's the works going, or it hasn't started yet? I also kinda interested in changing opamp on x3ii as well
