Hi Fi Tuning fuses

This year after upgrading lots ot bits, I probably can hear stuff like which way a pair of cables sound better...I may move the checking it out to a higher 'to do' than number 4,892,342 on the list.   
The recent breaking in of a whole pile of duplex outlets, then the current breaking in of new this week (6) Pangea AC14XL powercords(BTW they are not as good on the amplifier as on sources)Yes yes I still think about the Hurricane for my amp... That too is on the to do list (actually borrowing one is the to do.. buying is dependent on the sound)

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
