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.
