Periodic replacement of Audio Grade Fuses?

I just installed 2 Isoclean Power 24k gold fuses in a pair of Quicksilver mono amps. I am very happy with the results.

The card that came with the fuses stated "Fuses always carry high electric current thereby easily causing metal fatigue. This would then adversely alter the conductivity behavior of the fuse element and hence the performance of the equipment. Under normal conditions, Audio Grade Fuses should be replaced from every 6 to 12 months the longest."

I have had regular Buss fuses in my equipment for many years without need for replacement. It would seem that if the fuse element fatigues enough, that the fuse would blow or fail. At $50 a pop, this would add up. Seems that regular replacement is sales hype and would only benefit the fuse manufacturer. I am not electronically tech savvy.

Any thoughts on this?
Thanks.

An aside. Watching a fountain the other day, i marveled at how water never wears out. Never. It may change and separate into the atoms, but water just does not get old.
Atoms just survive a long time.
Metal is just a bunch of atoms. Thenare not wearing out.
maybe they get corroded, chemically interact, but basically they do not 'wear out'
So screw the idea fuses wear out.

Now light bulbs wear out. But we all know of some light bulbs which last for 20 years.. Rare, but around.
So most light bulbs are designed to burn out sooner. Planned death.
Maybe the OP's fuses have a planned failer? so they have to be replaced?
I would thus say stay away from that brand. As they actually may be making them to fail in a short time.

LOL!! Don't forget that the cables carrying the signal wear out too. Cables need to be replaced every 12-24 months. ;^)

The life of incadessent light bulbs is a very well understood function. It is the applied voltage to the fifth power. At any given voltage level you can have a very bright light which burns out quickly,or a dim light that lasts a long time.

Did you ever notice the behavior of the red lights at railroad crossings. They run those standard 115 volt bulbs at 90 volts, and, even with many ON/OFF cycles, can expect a life of 100 years. Bulbs made for EXIT signs are also made to last a long time. The landing light bulb in a Piper Cherokee plane is good for less than 100 hours, and the damn things cost about $40 :-(
