Hi Fi Tuning fuses

What! Whoa! Another direction person?! OMG! What’s that make now, 40,001? Well, shut my mouth and call me corn pone! 😛

Most likely Kimber cables have arrows for some other reason than wire directionality. Maybe shielding direction, who knows? I never perceived Kimber as being at the forefront of Cable technology, but maybe that’s just me. What I do know is than many high end cable and electronics makers are at least two paradigm shifts behind the power curve. Fuses, wire directionality and power cords are excellent examples. It certainly appears they all either never got the memo, like yourself, or completely dismissed it as too much trouble to get involved with or else it’s just too late to change their ways. Mule metaphor.  Dog metaphor, Old dog, New tricks. 🐩

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.
