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!

Lemon,
To be fair, that bumblebee business with scientists declaring it should be impossible for them to fly is a complete myth, like leprechauns and Eskimos.....
I think the idea of these threads is to contribute in some meaningful way,

@lemonhaze, fusers have nothing meaningful to contribute, it’s all snake oil and voodoo, or at least expectation bias on first hearing from spending $>160+ on a re-badged 50c fuse, they need to hear something, even if it’s in their delusional heads.

Here’s something meaningful since you asked
Do some maintenance on you equipment, clean the end caps up on your 50c fuse or re-new it if aged and looks nothing like the left hand one and starting to look like the others https://ibb.co/SQ9WJLn or https://ibb.co/HtnGV2p
And clean it’s fuse holder with proper "electronic contact cleaner" squeeze the fuse holder contacts together a bit more for added tension. And their will be the same expectation bias listening result.

Cheers George
@lemonhaze - Not to be contentious, but; Scientists couldn’t explain why Bumblebees could fly, with the Science (Physics) of the day.     Once Fluid Dynamics hit the scene; they figured it out.      I’d used that exact illustration, to explain the points we’re trying to make, here, years ago.      There are too many things in this universe, that WORK, whether we can explain them, hear them, like them, believe in them, or not.     ie:
From 09-22-2014 8:08am   :Another way of looking at it:   It was patently
obvious(providing they could see) to the earliest Aeronautical
Engineers, that Bumblebees could fly.     A problem existed,
however, in that early Science could not provide an
explanation as to how or why, let alone hovering.    
Understanding was limited to the principles of lift(per
Bernoulli).    Not until scientists began the recent study of
Fluid Dynamics, could they fathom how those small wings,
regardless of how fast they might flap, could possibly get
such a fat ass off the ground!    There are a plethora of things
audible to those that can hear and/or are willing to listen,
explanations notwithstanding.     Many things that we don’t know
how to quantify or explain(YET).
Then: there are those that will waste their keystrokes, on the endless, vapid preaching of the Naysayer Doctrine.      Ya just gotta believe their faith-based religion, or suffer their ubiquitous diatribes.
Try not to get into a war of words with Georgie. He's only here to add to the number of threads he can get closed down once they've become contentious. He's even boasted about it. He gets his kicks doing this sort of thing.

If you've noticed, he'll start out advising, and then when things don't go his way, he'll instantly turn on the people he pretended to help, insulting and denigrating them. It's his MO. 

All the best,
Nonoise
