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 hope you tweeks are still touting directional fuses to let your alternating current go back and forth through your wires. i would hate to see you cry if you understood how electricity works.

@danvignau  It appears you didn't read the first page of this thread:
As to why the fuse makes a difference, its easy to measure. Its the AC voltage drop across the fuse. Because fuses have to heat up in order to blow. as the amp is playing peaks, the voltage drop increases. The contacts on the end of the fuse make a difference too- which has led to the idea that fuses are directional (they aren't). Its just that sometimes the fuse sits better in its holder if you turn it around (although by simply rotating the fuse you can get the same effect, which can be seen by a reduced voltage drop across the fuseholder).

If a piece of equipment, let's say a CD player, has multiple fuses, let's say eight of them, how does the improvement go? Is it linear improvement depending on the number of expensive fuses used, or it is some other relationship? Is there a certain minimal number of fuses needed to improve the sound or it works from the first one?

maybe it means that when the fuse blows, another fuse across the universe blows at the exact same moment in time
That reminds me of the Steve Wright comedy bit where he found an on/off switch in his house that didn't seem to be connected to anything.
He tried flipping it on and off many times, checking throughout his home to see what it was connected to.

After a few more times turning it off and on, he got a call from someone in Iowa saying, "Stop doing that."

All the best,
