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!

Maybe it is expectation bias in some cases, although as I stated before, I went into it thinking SR Bluest were snake oil but thought I'd give it a try. I was shocked that my old ears heard a positive difference. If my brain will create an improvement in sound that really isn't there, GOOD. I'll buy more snake oil. We're all trying to get more out of our systems. If you're imagining that the sound is better, but it really isn't, who cares? You're happy because you hear the difference, and that's all that matters. This is a situation in which being scientifically right is not as important as the perception. Plus, the economy is in shambles, we need people to spend money.
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.
You really are, a delusional fuser

Like I said @lemonhaze
  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
No one should ever have to go and open their gear to get to and clean the contacts of a fuse holder. What rubbish.

All the best,

Yes, even the fat ones. 
Thought scientifically impossible until the advent of the airline ticket...
