Synergistic Research Fuses vs cheaper ceramic fuses

Synergistic Research is a con...  plain and simple.
These are just commercial fuses with fancy labeling and a bunch of pseudoscience mumbo-jumbo made up to shucker you in.

Con men prey on our "expectation bias" with their pitch.  If anyone paid that kind of price for a fuse I'm sure they would think it sounds better... Just ask any psychologist. We are all susceptible to this.

As a result of this post I ordered a couple Littelfuse 285 series, their orange ceramic with gold caps. One for my PrimaLuna and 1 for my Innuos Zen mkIII. Hey, its $20, what can it hurt to try. I'll let you know what I hear. 

If an expensive fuse did nothing at all, most would keep it because it MIGHT be making a difference, the purchaser is past the angst of payment, and it still feels like a caring investment in the quality of the system they care about.  Since any returned fuses can be resold as new, the money back guarantee is a great marketing ploy.  But at these markups, no financial need to  resell them.

Its funny how nobody talks about the fact that system upgrades are all relative.

Replacing a fuse in a garbage amplifier made of 6 wires and radio shack components will do little. But removing a radio shack fuse made of junk metal in a $40k Kondo amp will free an incredibly weak link in an otherwise transparent system. Its like washing a filty dirty window in a Ferrari will cut your lap times in half because now you can confidently drive extremely fast, while the guy in a broken down wishy washy honda says "What kind of person claims that cleaning their window makes them cut their lap times in half?" because no matter how hard he drives, the car will only go 1 second faster to begin with. 

This goes for differences in system noise, poor power, etc. 

When people come here and speak with such objective certainty about components...makes me wonder.
