I especially find that the power chip give the best overall improvement. Very powerful sounding and doest lean out certain frequencies.
Capacitor, fuse , transformer and ic chips add overall clarity but they towards a drier or leaner sound.
As for the cable chips i found least impact, but of a drfferent, smoother sounding.
Having tested the bybee, they are different. They do add clarity but found that it seems to impact the staging and dimensionality in the soundstage which i never experienced with the wa chips. Strangly, It seems to also have some impact to the sound of the room.
I need more testing as im not sure if it lose some dynamics or added some mellowness to some instruments and it gave the opposite effect on different type of music.
