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!

graphene, diamond dust  (12-1600), and a dab of nuclear never seize, thin it with mineral spirits for a slow dry, and or lacquer thinner for quick dry.

Paint the silly thing, and let it settle in the working position for a while, let the fumes evaporate if you just painted it, or turn it on and blow your face off. :-) DON’T DO THAT... DON’T BLOW YOUR FACE OFF. Unless your real ugly. Thats a preference of mine, I like ugly. :-)

Back to the lab/shop/basement/bunker/PLACE...

How many fuse doubters have tried them?

How many who have fused up have thought the “upgrade” did nothing?

I have tried on two Amps. One was a yes the other a no. Yo.

While I don’t have the answer to any of your questions, I can tell you that in my Nuprime amplifier, the Synergistic Orange fuse was nothing short of unbelievable. This is the best tweak I have ever tried and I have absolutely no regret. If you have $160 on a credit card, give it a try. If it doesn’t work for you just return it, no question asked for a full refund. 
Gents,

This is how I'm wired and what I thought about in going from from Blue to Orange. Color stuff is in my wheelhouse but not as high up a dog walking....hang on..let me finish this post first. 

In subtractive colors the two make black. "I want my baby back."

If additive colors you get a deep purple...."smoke on the water". 

I would like to get in Millercarbon's room and I'm scheming of building a purpose built out budding too. I may never get there but the dream is alive.
