@b0bb and @Xoverman100uF 10V solid tantalum bead cap for Vcom bypass.
The vcom reference circuit is very low current, conventional aluminum (Al) electrolytics leakage is quite high and not temperature stable.
Solid tantalum beads have very low leakage, about 10-50x lower than conventional Al Electrolytics and is stable across a wide temperature range.
This improves the low frequency common rejection of the dac, it practical term gets you lots of low and very fast bass.
What it does.
1) Substantial low end extension improvement
2) Bass slam impact increases
My board layout is different from B0bbs which I've been following his mods. I may have a second generation LKS board compared to what you have. I am interested in adding the 100uf 10v yellow caps you added to my board and replace my blue caps with the wima red caps you have surrounded around your gold caps (see where you marked 5 in the next post - which contains a copy of the modifications you did to your board). Would this be a recommended upgrade if I have a different generation board? My caps are black caps with a brown stripe on it. I am enclosing pics of my board to compare if this helps.
Thanks much.
