on vcap cutf, i have bought a total of:
1) 12 x 0.01uF
2) 12 x 0.22uF (lower voltage)
i use them as by-bass...gradually, i put them on transport, dac, pre-amp, mono-block, cross-over, power-plant
a) it helps a lot on making the sound to be closer to the real sound
b) i can hear more details after putting them on
c) the sound seemed slightly hi-fi initially BUT it keeps improving untill the sounds were quite natural(over a few months of use)...actually, when i invited friends to come to listen, no one commented a "cold" or hi-fi sound
before i put in the v-cap cutf, my hifi(each component) is heavily loaded with
Blackgate,
Mcap silver/goldsilver/goldsilver in oil,
Ampohm copper/polyster/aluminun/tin in oil and in wax,
