Synergistic Research Fuses vs cheaper ceramic fuses

You can semi cryo fuses, cds, cables... by introducing them first from your refrigerator then into the freezer, then back to the refrigerator. Do a search for the technique

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.
