After finishing the semi-DIY power conditioner, I notice the bass of my music is much more controlled, there is better attack in both the bass and treble, and the treble is cleaner and hence I can hear more things in it.
The only thing is I haven't even plugged in the power conditioner yet.
Woo, must be those "suddenly the music sounds better" periods. Like when you come back home from a field camp.
Imagine if I did plug in the power conditioner. Then all these "improvements" would be attributed to the power conditioner.
Did I hear a difference? Yes, I think I did. Is this placebo effect? Well, given the current situation of things, duh.
So one can hear a difference with placebo effect.
Placebo effect owns.
