I just change my old “Aruki” Korean oil-can capacitor to ASC and Mundorf MCap Supreme. The configuration before is 60 uF and 40 uF Aruki Capacitor, now changed to 3.3 uF MCap Supreme and 40 uF ASC X386s.

The effect? The mid and high are getting more liquid. Background is even darker, with better separation and richer timbre. No surprise some people love the film and oil capacitor on the Power Supply section, and this MCap + ASC combination also proves such theory.

For cheaper solution, I usually go with Solen or SCR.
