Determining current flow to install "audiophile" fuses.

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, 

"Also in order for the experiment to have any validity at all you would have to be able to re create the same situation , over and over and over again. i.e. you should be able to hear that if someone had changed the direction of the fuse without your knowledge - I’d state that this would be impossible."

Of course it could be a lot of things. It COULD be a change in house AC voltage, it could be a change in the weather, it could be oxidation is removed from the fuse holder, it could be explained by a change in the time from day until late at night, changing something else in the system at the same time of the fuse change, the placebo effect or any number of other things. We already know that. It’s the same for the test of ANYTHING. Do you think audiophiles fell off the turnip truck yesterday? And why is it the skeptics who always accuse audiophiles of doing tests incorrectly never actually roll up their sleeves and do the test themselves?  Hmmmmm...

Expectation bias expectation bias is no doubt a factor.   I did the audiophile fuse thing recently with a synergistic red fuse in my arc sp 16 recently using a fuse given to me to try.   I thought I heard some difference with that versus stock fuse at first but could not be certain after repeated tries.   Reversing directions did nothing.  I wanted to hear something but did not feel compelled to having been given the fuse.

in any case if there was a difference it was too subtle to be assured of.    As it stands I am not seeing the value clearly.  

My my only suggestion is for each to report their experiences but realize not all will hear same results.   The reports I read including my own experience seems to bear that out.   Be Leary of anyone promising anything or attempting to sell their spin as fact. 

I had different clients who used fuses already so I knew their stories. But I was sceptical as well. But after some tests I had to admit that I was wrong. Mann it makes a huge difference

In 2015 we started to change the electric cables inside in the houses of cleints and we use the Siemens  Ultimate Cylindric Fuse Cartridge. And creating a group only for audio

I seldom had so many enthousiastic clients about the improvement. Because it is not that expensive.

Biside we have sold many Hi-Fi Tuning fuses to be used in: sources, amps, pre amps, subwoofers and even speakers.

Most people called it the best investment they ever made in audio. 

Beside fuses we also started to change the electric cables inside amps by Audioquest NRG-10 wires. We buy them in bulk and we separate the wires of the NRG-10.

Audio is a never ending story and you can improve sound and quality over and over again.

I'm sure anyone selling high profit fuses is all for them.
