The secret to a great amplifier...

OP,

Would you say, Orange fuse been “Your most indispensable tweak"?

When you know science and reason has lost the war is when you have people claiming that those who want to see evidence to support observation is considered on par with Qanon nuts and subjective claims are considered the gold standard. I think it's the other way around,  extraordinary claims of supernatural hearing abiity are like those who claim they've seen aliens from distant galaxies and don't ask for evidence to support their visual accuracy or you're a conspiracy theory crackpot.

Why would someone seeking scientific evidence come to a hobbyist's site with their demands? It doesn't make sense, unless the goal is simply to argue and disrupt. No one here owes scientific proof of anything to anyone. If you seek absolute proof, you're simply in the wrong place.

If someone gave me one, being a reasonable person, I would try it.  But I will not buy a $150 fuse.  That's too nutty even for me.  

Think I'll leave my amp just as it is. Interesting though it may be....
