Determining current flow to install "audiophile" fuses.

Hello Ralph, 
I'm pleased that you acknowledge and respect the listening impressions of your customers regarding premium fuses rather  than belittling their informed feedback to you. Good quality  audio components exploit the impact of these fuses.
Charles, 

Ralph graciously acknowledged his customers were adamant regarding positive results with upgrade level fuses. They had no comments in regard to fuse directional properties. George I understand your position concerning fuses, that has nothing to do with some of Ralhp's customers. Not everyone shares the same viewpointas you. 
Charles, 

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.
Best Re6,

Hello Peter,
Yes, this explanation has been suggested before. 
I've gone back and forth several times with my DAC, Line Stage and amplifier and the differences heard remain consistent. My friend whom I mentioned earlier has a very different system and room compared to mine yet the findings are very similar. The changes are not profound  (no need for hyperbole ) but are quite noticeable. As this thread and other past threads have demonstrated,  some agree and some don't.  I have nothing more to offer. 
Charles, 

That 112 dollar sandwich may or may not taste good (for that price I hope it does). Taste good or not it won't improve the sound of an audio component. The good news is the SR Black fuses have improved sound quality for "many" experienced music lovers on this forum. Tbg  you're right, there are numerous observable phenomenon yet to be explained by our current knowledge of physics.
