The secret to a great amplifier...

Is a $150 Orange fuse from Synergistic Research. Seriously, extreme boost in sonic performance. Blacker background, larger soundstage... if I wanted to make some bucks, I’d put these is cheap OEM compnents and start letting the accolades and purchasers come calling.

Mind you, I have a high value-oriented $20k system, so it was nice before, but damn!
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.

Again:     No one can possibly know whether fuses will make a difference, in their system and room, with their media and to their ears, without trying them for themselves.      Some companies offer a 30 Day Satisfaction Guarantee, so- those that are actually interested, have absolutely nothing to lose.     Anyone that knows anything about the sciences, realizes that something like 96% of what makes up this universe, remains a mystery.       For centuries; humanity’s seen, heard, felt and otherwise witnessed phenomena, that none of the best minds could explain, UNTIL they developed a science or measurement, that could explain it.     The Naysayer Church wants you to trust their antiquated science (1800’s electrical theory) and faith-based, religious doctrine, BLINDLY ("Trust ME!", their credo).    Theories have never proven or disproven anything.     It’s testing and experimentation that proves or disproves theories.       IF you’re interested in improving your system’s presentation, have a shred of confidence in your capacity for perceiving reality and trust your own senses: try a better fuse, FOR YOURSELF.           The Naysayer Church HATES it, when THAT happens!
