Periodic replacement of Audio Grade Fuses?

Due to the environmental concern for properly disposing of these "fatigued" fuses I volunteer to collect them from you and place them somewhere they cannot adversely affect YOUR equipment.

It somehow does not surprise me one bit, that some missed the point of the post. No one stated that old fuses would FAIL, but simply would have an effect on the performance of the equipment(not sound as good as fresh ones). Can't say as I've heard any degradation, in the years I've been using HI-FI Tuning's products, but- I haven't tried new ones, compared to old, either. Probably won't!

I use neodymium magnets instead of fuses...thru-out. Have not witnessed the least amount of magnetic down hill slide.

We tend to think of fuses in an almost binary sense, ie the circuit is closed or open depending on fuse state.

But fuses are resistive devices designed to essentially "burn out" at the right time. Heat is generated to various extents at all times by design to accomplish that goal as a result of resistance designed into the fuse . I suppose its very possible the heat alters the composition and electrical conductivity characteristics of the fuse element prior to "blowing" in a manner that might effect the sound as a result in changes in electrical properties at some point perhaps compared to "new".

I'd be willing to bet that this is perhaps a reason why some hear a difference when replacing an old fuse with a new one, especially an "audiophile" type fuse where one is perhaps tuned in and listening for a difference by design when making the change. Better electrical contacts at the fuse holder as a result of the replacement operation is likely another at least as significant as anything else. Some report "Better sound" replacing a fuse with even a fresh conventional fuse compared to some fancy fuses.

It's all about as clear as mud but this makes as much sense to me as any other theory or reason why different fuses might sound different.

Replace all components the moment they are fully broken in, because after that point, degradation is surely occurring.
Knowing this you will never be able to just enjoy listening to music.
