Directional? I put them into four different components. I reversed the one in the line-stage ... and it sounded better. By "better," I mean more well focused. Same as all of the other aftermarket fuses. Placed the wrong way, the sound is slightly defused (no pun intended), like the system is out of phase. Placed in the proper direction, things just seem to snap into place. I know ... I know .. Impossible, right?
