The secret to a great amplifier...

The fuse that was called for always blew when volume was increased

You never heard it at the level you wanted.
Music always sound better when you want to hear it at the volume level you want, sound quality had nothing to do with the fuse, you were just enjoying it more, because it was finally louder.

Yes they improve the system.  Keep in mind fuses are also used inline for speaker/amp connects (no power only).  For those who are more budget minded the litlefuse 285 slow blow and 218 fast-blow are great options under $10 each. 

After doing some research I found Littlefuse sells AUDIO/MEDICAL quality fuses Series 285
they are all slo-blow, buy come in various sizes including 5x20

The 218 series ceramic are fast-blow fuses, but not the audio grade.  Still an improvement over glass fuses.

Did a/b and there were an improvement in my amp, and preamp. I personally prefer a known engineered part with industry / manufacturing standards then taking a chance with any audiophile fuses that do not have any standards.

I am not saying all audiophile fuses have no standards. So use caution.

     I was wondering if anyone has bought hundreds of dollars worth of these magical orange fuses, noticed no performance improvements  and blew their own fuse?

Based on all the report of these magical orange fuses blowing, I wonder whose fuse would blow first :-)

I hope they are not taking a low value fuse and marking it as a higher value. That would be one way to reduce the noise in the power supply.
