Hi-Fi Tunig Fuses & Parasound A21

Geoff, note that he said "reasonable explanations."

Yes, I know. Please note that the explanations I listed are quite reasonable, at least to a reasonable person. In fact, I don’t think it would be going TOO FAR to say they are SO reasonable that it’s a confounding mystery why someone didn’t come up with aftermarket fuses prior to 20 YEARS AGO.

No not shilling, just trying to keep things honest. 
You have yet to come up with any real explanations of why you firmly believe that mains fuses the magic cure and are immediately detected as being directional, and so can transform the sound of a system as you say.

These discussions of the perceived sound qualities of fuses and cables, etc. never cease to amaze and amuse me - passions are stirred and frustrations are aired, never with definitive resolution.  

And... skeptices rely on science and engineering principles, while believers "hear what they hear."   

I tried the Audio Horizons Platinum Reference fuse in my ARC Ref 3 Preamp and was able to discern, perhaps, a subtle difference... not really certain... it was so subtle.  

In the words of one now very much infamous "at this point what difference does it make" - "Never the twain shall meet." 
 
Those who hear an improvement will never be persuaded they really don't, and those who do not hear a significant improvement will never be persuaded they really do.  C'est la vie...

Good. Then you won’t mind answering a few questions.

1. do you think directionality of fuses is audible when used in speakers?

2. do you think there are audible differences among various mains cables themselves? How about among mains cable connectors?

3. do you think there are audible differences among various capacitors in the mains circuit?

4. are you aware that HiFi Tuning’s data sheets show differences in directionality in both measurements and audibility of fuses in AC circuits (as well as in DC circuits)? In other words, directionality of fuses in DC circuits is not really as controversial as uber skeptics like to believe or pretend to believe, whatever. Wake up and smell the coffee.

to be honest I did not say any such thing. Please don’t put words in my mouth. Furthermore, there are many reasons why aftermarket fuses are superior to stock fuses (in sound quality), not only directionality. as I just got through explaining. But directionality is one of them.
