synergistic research orange blue fuse direction.

@millercarbon I read your explanation twice, which is two times more than it deserves, and in those two readings I could not find a hint of an answer to the simple question fistatus1 posted.  Just nonsense.  And then when you finally do try to actually answer you go completely off the rails and talk about converting to DC - ignoring the fact that the majority of fuses are on the incoming AC line, not on the rectified and filtered DC.  Your lack of understanding makes you a perfect candidate for the pseudo-scientific claims foisted by Ted Denney and his Synergistic Research con men. 

@f1status1  Fuse benefits and their directionality are not a real thing, but the nastiness and name-calling of their proponents is very real.  Do not try to reason with common sense or solid engineering - if Synergistic Research says the sky is green then you are an ignorant moron if you don't see it that way.  Find another thread that may have some merit, or continue to monitor this one for its entertainment value.

Again I state that arguing from the standpoint of common sense or sound engineering is pointless here.  These people hear significant changes when a fuse is reversed.  This in itself is remarkable just because a long period of time has elapsed in the reversal process - unless the device's cover is left off and the innards exposed, which is probably more damaging to the sound that the effects of the fuse.

Of course their aluminum foil hats also affect the sound.  

@geoffkait  " The reason it’s called common sense is because it’s so common. Thanks for playing anyway."

I guess then that I am just a commoner doomed to struggle day to day with only electronics and the sciences as a guide.  Never to attain the lofty goal of extolling nonsense as truth and truth as nonsense.  I can only take solace in the fact that there are so many of us and so few of you.
