The .01uf Tinned copper has been an absolute revelation.
I was up till 7 in the morning listening to album after album, non stop.
Everything sounded like I was hearing it for the very first time..... I am dumbfounded by how much of a difference these little capacitors made in my setup.....just dumbfounded.
Burn in has been especially crazy, at one point the sound lost all color, I have never experienced that before...and it came back after a while, and the sound became so incredibly liquid, and the soundstage became the most holographic I have heard on a speaker as of yet. Sadly that phase only lasted for a few hours, and I am hoping maybe they settle in eventually something close to that.
But either way, the clarity, coherency, and timbre are just exceptional.
This experience has convinced me, when I get my Magnepan 20.7s, I am building my whole crossover with just Duelund capacitors. Not settling for anything else.
