What's going on with Synergistic Research fuses?


I live in California and a couple of weeks ago we had strange lightning storms that started the many fires burning in the State.  It also fried the fuse in my Pass XA30.5.  I got the amp second hand and it came with a SR Blue fuse.  I called Pass and they recommended a very cheap fuse which I ordered and installed.  Because I was curious, I took the SR sticker off the old burnt out fuse and found that it was a very cheap SIBA brand fuse underneath.  It is clear that SR is either not making the ceramic casing for this fuse or using the SIBA fuse and then doing stuff to it.  At the very worst, it's just slapping a sticker on it and charging a ton more

The thing is, I'm pretty sure I could hear a difference for the worse when I installed the cheap glass fuse post lightning storm.  Could it be that SR is modifying an existing fuse to make it sound better?  Maybe some more technically minded folks here on the forum could help me understand

thanks!

" i would hate to see you cry if you understood how electricity works."                                                No one, "understands" exactly how, "electricity works".      That’s why there’s so much Electrical THEORY.       The number of Wiki-Scientists on these pages, attempting to win the IG-Nobel Prize in Pseudo-Physics, is always amusing.                Whenever some educated someone actually does discover how exactly how electricity does function, they’ll be lauded by the scientific community, will have solved some of the disparities between Relativity and Quantum Mechanics, receive a Nobel and we’’ll hear about it.      Newton’s THEORIES were largely superseded by Einstein’s, then came Feynman’s.       For now; none of you can prove your statements (theories), regarding fuses, wires, or anything else, as regards our systems.      The following are for your edification/education/correction (which is why most of you won’t bother to read the links): https://www.thegreatcoursesdaily.com/how-einstein-challenged-newtonian-physics/      then: http://hyperphysics.phy-astr.gsu.edu/hbase/Forces/qed.html#:~:text=Quantum%20electrodynamics%2C%20co....      and: https://bigthink.com/philip-perry/an-updated-feynman-experiment-could-heal-the-rift-between-quantum-...                  Happy listening, even to those that refuse to follow the scientific process of observation and experimentation, in their own systems, with their own ears, FOR FREE (30 day return policy).

Exactly what have you tried many times? What experiments have you personally performed to answer the question of whether or not fuses make a difference? Were they double-blind tests? I am not attacking you, I am simply interested.

Wow!  Sometimes I envy you guys. Life must be very easy for you. All good amplifiers sound the same as long as they have similar specs, right?  There are seven colors and no more. Pace, rhythm, soundstage, musicality, timing are all pigment of our imaginations. Your innocence is admirable. Too late for me though. I cannot go back. I heard it, I heard the music and I want it in all its glory and in all its simplicity. Keep safe.
