Direction of aftermarket fuses (only for believers!)

It is with reluctance that I start another thread on this topic with the ONLY GOAL for believers to share their experience about aftermarket fuses.
To others: you can call us snobs, emperors w/o clothes,... etc but I hope you refrain posting just your opinion here. If you did not hear any difference, great, maybe there isn’t.

The main driver for this new post is that I am starting a project to mod my NAD M25 7 ch amp for my home theater. It has 19 fuses (2 per channel, 4 on the power supply board, 1 main AC) and I will try a mix of AMR Gold, SR Black and Audio Magic Platinum (anyway that is the plan, I may try out some other brands/models). As it is reasonably difficult to change them, esp the ones on each channel module that requires complete disassembly, I would like to know what the direction is for these models mentioned and of course, others who HAVE HEARD there is a difference please share your experience on any fuse model you have tried.

Fuses are IME directional:
Isoclean is one of the first to indicate the direction (2008/2009) on their fuses. Users of HiFi Tuning (when the awareness rose quite a bit amongst audiophiles) have mostly heard the difference.

As an IEEE engineer, I was highly skeptical of cabling decades ago (I like the speaker design of John Dunlavy but he said on many occasions that cables nor footers matter at all, WRONG!). Luckily, my curiosity proved me wrong as well. I see the same skepticism that I and many others had about the need for aftermarket cables many, many years ago now on fuses and esp on the direction on fuses.

Another example is the direction of capacitors (I do not mean electrolytic types). Even some manufacturers now and certainly many in the past did not believe it can make a difference sonically. Maybe some do but it takes time in the assembly to sort and put them in the right direction/order (esp as some of the cap manufacturers still do not indicate "polarity") so that maybe is one argument why this is not universally implemented.

I'll talk to anyone who will listen.  Heck, I'll even talk to someone who won't listen. Think of it as Tibet Book of the Dead for Audiophiles.

Geoff, there are very specific questions being asked by the OP looking for very specific answers to apply for his NAD.

I’m waiting for your expert advice to help him.

I’m not biting on any baiting here . Let’s stay on topic.

Again, so much internet space wasted ... the reason for starting a new thread is exactly what I try to avoid:
on the previous one onlookers and know-it-alls filled up 90% of the thread with their assumptions.
Reading through close to 300 posts yielded little valuable, practical info.

On most threads we get comments "sure, go ahead and try this and that, as long as your wallet is comfortable with it", YMMV, etc but no, on the previous thread too many needed to voice their doubts about the direction of a fuse. Ever tried to ask some of the questions here on a forums at, say, Best Buy, like "does cable matter?"
You promptly will feel exactly the way how I feel here, thanks "audiophiles"! Great help! 

For clarification, I solicit comments like"
"..with the Audio Magic BeeWax, the direction goes like the lettering on the fuse (like HiFi Tuning)..."
