This is only my opinion, but I have been around the try this and try that capacitor loop and went back to a 0.022uf ceramic disc. I am an audiophist at heart and would have thought this would have been the last one to consider, but it seems to give the most balanced tone.
BC Orange drops seemed to scoop the mids a tad
Spague Orange drops seems to have more low end and less top
Mylars were good but lacked clarity.
However, each to their own. Everyone needs to make their own choice! Buy a range of 0.022uf capacitors and a toggle switch and switch between then and see if you can hear the difference.
