Determining current flow to install "audiophile" fuses.

Naw, it was to imply that there's no real answer here that can be agreed upon.

However, there's this yellow bricked road that leads to a wizard......

"Naw, it was to imply that there’s no real answer here that can be agreed upon."

Let’s just write the whole thing off as another one of those controversial things that get audiophiles’ goat. If someone didn’t come along many years after Einstein published his General relativity theory and demonstrate that gravity bends light the science community would still be scratching it’s rather pointed head and muttering the same thing, "There is no real answer that can be agreed upon." Not to mention LIGO finally observed gravity waves from a merger of two monster black holes just a couple months ago, confirming Einstein's prediction - 100 years after the fact.

I bought HiFi Tuning's Supreme fuses ($50-$80 each) and they did make a difference in sound quality, not huge, but good.  When I got them I asked some very knowledgeable technical people including the place I bought them (The Cable Company) if the fuses were directional, and they all said fuses are non-directional ("they change direction 60 times a second").  Nonetheless I experimented with changing their direction, and did find a small but significant difference.  Go figure.  Ears rule.

Jmski,
"Ears rule" well that's how it goes for me as well. 
I have upmost respect for the technical knowledge and contributions of Al and Ralph,  this is without question. I make no attempt to explain fuse direction effects, I'm unqualified to do so. I do trust what I hear in my system and accept that I lack any technical justification. If some want to attribute this to expectation bias, okay fine. 

For what ever the reason may be there is a difference in sound when  fuse directions are reversed. I hear it easily in my system  (8 watt SET amplifier ) and my friend's system using a 300 watt Krell amplifier. Why? I don't know, I hear it and my friend easily hears the same sonic changes. 
I do know man has observed many phenomenon for many years before science could reasonably offer an explanation. 

So I'll leave the arguments to others and just enjoy and appreciate what I hear.  "Ears rule" applies for me.

I have observed Audiogon forums with great interest for some time, but have never been motivated to participate until now.  Although skeptical, I remain open-minded re. fuses, having never tried them.

When I was young, my dad offered up many pearls of wisdom.  For example, he often told me "if you had another brain it would be lonesome".  An astute observation as it turns out.  Once we had a dog that barked incessantly.  When I asked my dad why, he said "he just likes to hear his head roar."

There is much head roaring going on regarding fuse directionality.  You dogs know who you are.  Quite a pack!  Sorry I couldn't be more positive.  By the way, I would guess that these dogs bark loudly and carry a little stick.
