Aftermarket Fuses

If these greedy manufacturers weren’t so stupid and priced their products reasonably, they would sell a lot more and some of this resistance against such tweaks would fade away as more people would witness the audible difference.

While I kind of agree that the prices do appear to be steep I really do not think it would make much difference how they priced them tbh.
Even if the SR Blue was priced at $50 say instead of $150 there would still be plenty of naysayers claiming a $2 Littelfuse is all you need!
Might they actually sell more?
Possible.
Would the revenue they recover exceed that if priced higher?
Doubtfull imho.

To the OP and Oregonpapa....I'm going to be ordering the SR blue fuse to go into my Auralic Vega G2 streamer...and was wondering what specific piano pieces you listen to for your comparisons.  I'm going to look for these in Tidal to do a comparison versus my stock fuse.  In regards to the fuses, I was deciding between the Audio Magic Beeswax Ultimate and the SR blue, but there doesn't seem to be much written on the Audio Magic...and the SR blue is less expensive.....

One of my references is Marian McPartland's Reprise- Hickory House Trio from 1999. Well performed and recorded jazz music in an intimate, live setting.

When it comes to fuses, I really believe in Winlyn brand. The fuses work as advertised, I had a blown fuse for over a year for a charging port that I really didn't care about it now it works.
