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!

cakyol...Thank you for answering my questions. I have no doubt about your credentials. But, if I accept your assertion that fuses cannot possibly make a difference, what do I do with the improvement my brain perceived I got when I replaced the fuses? I'd like to keep it.

thecarpathian...The term "Eskimo" is considered by many who have traditionally been called this to be a derogatory term. In some dialects of the common language it means "one who eats raw meat". Just sayin.
cakyol...If everyone reads your last post directed to me, it should go a long way to lowering the temperature on this thread. Thanks
The truth shall set you free. I was listening to Coletrane' "My Favorite Things" last night and was enjoying the expanded sound stage and sharper imaging since I put in the SR fuses. It sounded like Coletrane was in the room with me. Roy Haynes' solo on drums was crisp and dynamic. And then I thought about cakyol's assertion that it's all in my head, so I thought I'd test it. I repeated to myself over and over; "It isn't real, it isn't real." But it sounded real. I kept at it for at least 15 minutes and then it happened. The instruments started moving closer together and no longer went as far past the speakers. Coletrane seemed to fade a little further back and Haynes lost a little of the sharpness and clout. It still sounded good, but it seemed to lose a little. What it lost, of course, wasn't real, so I knew I should appreciate that I am no longer delusional. Thank you cakyol for opening my eyes and helping me to see the light. The dream is over.
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.

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.
+1 ivan_nosnibor...It seems to be getting worse. Perhaps he should take his own advice from other threads and if he doesn't have anything positive to say then "move along". Hope he doesn't forget to delete his posts.
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.
