Going to @MazeFrame @TechnicolourDunk @MacDLaw as I know you guys are especially suckers for internal shots…
So some progress pics from the Cowon Plenue S I am having modded. Below are pics by Steve at NP Audio, and his explanation.
Top is a picture of the stock board…
Then with 19 ultra low poscaps removed…
Then with ultra low esr kemets. The battery power cap has has been doubled from 47uf 100uf.
A larger capacity, quite a bit thicker (just fits!) but shorter (in length) battery which is going to allow for some physically LARGE Audio Notes 
I’ll be removing the lip from the chassis were the stock battery ends.
Besides this we had a chat about opamps…
… After a little back and forth we decided to not change these. I know it is supposed to be the same thing but just higher spec but i also know opamps can change things a decent bit and I didnt want to stray too far away from what the player is. Also, tbh, I never head a Fiio that I liked.
