Hi Fi Tuning fuses


Has anyone used or is using HiFi Tuning fuses to benefit sound. Is is worth it to use in Ayre preamp, Mark Levinson 532h amp and possibly Benchmark DAC? Thanks for respectable replies.

I felt it improved the dynamics in my Cary tube amp but only if installed in the proper direction! Placed the opposite way it degraded the SQ."
@three_easy_payments, I can't tell if you're being sarcastic or not.
@2channel8  yeah, I guess it could have been taken as sarcasm.  I was being serious.  Direction made a huge difference.

I did put them down as recommended
But I did not change the directions
In order to hear that the result was better than 

But I ask a simple question
If the companies we pay them so much

They can not do this for us
Because a difference of $ 200 is really negligible to the price
Which costs $ 3500, for example

I have never turned to hearing if there are differences
Only if they are different from the original and there is a difference.
There are many other changes like polarity in electricity, and it changes certain equipment in the 90's
What! Whoa! Another direction person?! OMG! What’s that make now, 40,001? Well, shut my mouth and call me corn pone! 😛
Most likely Kimber cables have arrows for some other reason than wire directionality. Maybe shielding direction, who knows? I never perceived Kimber as being at the forefront of Cable technology, but maybe that’s just me. What I do know is than many high end cable and electronics makers are at least two paradigm shifts behind the power curve. Fuses, wire directionality and power cords are excellent examples. It certainly appears they all either never got the memo, like yourself, or completely dismissed it as too much trouble to get involved with or else it’s just too late to change their ways. Mule metaphor.  Dog metaphor, Old dog, New tricks. 🐩
