Furutech fuse

Back story. I find the prices of Synergistic fuses extortion. Like someone charging $100 for a cup of water in the desert. The product may have value as a tweak, the materials do not justify the price to me. 

However, ever the tweaker, I succumbed to buying a $40 Furutech 20mm 4 amp fuse for my preamp.

It’s rhodium plated OFC.

I tried it in both directions. Yes, it sounded more coherent in one direction than the other. I ran it for about 10 hours.

I did not like the sound. Etched and dry with reduced bass. I swapped back the original.

Please be aware that the Furutech rhodium fuses require a very long time to burn in (around 200-300 hours).  After 10 hours, you are already in the "painful" stage.  Keep the fuse in the preamp for another 10-15 days and then do critical listening.  It will actually go through several changes.
That being said, I think a 4A fuse is probably way too much for a preamp.  I would not put in more than a 2A, but I don't know your current preamp model.

@auxinput Noted. I'll burn them in on the other rig and try it again.

I heard through the grapevine that Audio Magic Ultimate SHD Beeswax Fuses are the bee’s knees. 🐝

Has anyone tried miniature circuit breakers instead?

Quite a few high end manufacturers use mini breakers now.

Not had the pleasure of owning one so equipped myself unfortunately.
