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.

Quite a few high end manufacturers use mini breakers now.

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

The idea with long burn-in is if you can get the poor sap to put up with your crap component for 100 hours by then he's gone through so much crap for so long cognitive dissonance (I'm not stupid, I'm not wasting my time, I'm not THAT guy!) kicks in and he'll cling to ANY improvement as justification and hang onto his mistake. Er, I mean component.

In reality every really good component sounds good right out of the box. Not great. Good. Then it sounds a whole lot better WITHIN MINUTES. Then it sounds great within hours- the same day. If its "painful" at 10 hours its not a component. Its crap.

Cognitive dissonance. Its a thing. Knowledge is power. Look it up. 
I do have to agree with Miller here.

It should sound better right away and only GET better as it "burns in".

The ONLY items I ever purchased new and hated and returned were a set of copper speaker  cables which just sounded excessively bass heavy and muffled right from the get go. Asked the manufacturer who suggested I let them burn in longer.

The general view of the Audiogon members was the same as mine, if it did not sound right to start with there was little hope it was going to improve drastically. So back they went.

I am always wary of these 200 to 300 hour claims of burn in especially with a 30 day return policy, do I need to add 2 and 2 for you......
I can certainly understand if someone doesn’t get good results right away because the fuse will not sound right if it’s out in backwards. And since fuses are generally not marked for direction there is no way of knowing which way is the right way without evaluating both directions. Hi Fi Tuning a long time advised that no matter which direction is chosen the fuse will burn in and somehow turn into the correct direction over time. But now Hi Fi Tuning and everyone else knows better.
