Hi Fi Tuning fuses

Newbie about fuses. 
I'm looking at my 4 HIFI Fuses to swap out with original fuses from my Statos stereo amp. How can you tell in which direction to install them correctly?

You can’t tell by looking at them. You have to try them both ways, one at a time. One way will sound better than the other.

Kat a mite. 😻

Why would we put any stock or trust in the opinions of audio equipment manufactures like Roger Modjeski, Nelson Pass, Roger Sanders, or any of the rest of them. What do they know about audio or electronics, anyway?

I’m thinking, though - If you have many thousands of $$$ in audio gear and it just doesn’t sound spectacular, instead of investing thousands more in cables and fuses, just change the direction of the cables and fuses you already have. Problem solved......Jim
