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!

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. 
I had to look up "NPC". Apparently it's a favorite insult of Trump supporters. From what I read it is directed towards someone who does not think for themself. How does this apply to cakyol? I don't agree with him on fuses because I heard a significant improvement when I changed out the original fuses and replaced them with SR Blues. Others have talked about the fact that the improvement might have been due to making better contact with the fuse holder. I can't say one way or the other. But there was an improvement that I had not expected. So while I disagree with cakyol on this, he seems to think for himself. Unless there is another definition for NPC that I am not aware of, and really not interested in, I don't see how it applies to cakyol. I would still like cakyol to answer my questions.
