To Fuse or Not to Fuse... That is the question!

Not eve(n) close. So worry about the big stuff, and dont fret the small stuff. And fuses just might save you from doing $1000s of damage.
really - its vastly smaller than you may think.

>>>>>I tend to disagree. It’s vastly bigger than you may think. Especially if one has many fuses.

Maybe we should have a thread, How Small Can Something and Still Make a Big Difference?

OK, I am totally confused. You guys saying you use these fuses in AC circuits?

From their web site:
A: Yes, fuses are directional. Electricity should flow from the left to the right when you view the fuse. If you do not know the direction of flow you should listen to the fuse inserted in both directions. One direction will sound more detailed. This is the correct way.

I thought AC changed directions 60 times a second?

>>>>>Thanks for bringing that up. Actually most audio fuses happen to be in AC circuits. It’s true current changes direction on the wire according to where the fuse is located. If the fuse is located where power comes into the CD player, preamp or amp or whatever it changes 60 times per second. But if the fuse is located in the speaker the current changes according to frequencies of the audio waveform. Thus the current at the fuse in the speaker changes 20 to 20,000 times per second - or more or less. If the fuse is in a DC circuit obviously current is unidirectional.

You can ignore the current traveling in the direction away from the speakers, I.e., toward the wall, since that direction of current flow is not (rpt not) audible. The only direction that’s audible for any wire is the one toward the speakers. It is the speakers that ultimately produce the sound you hear. So, it’s the “quality” of the current traveling toward the speakers that is the issue. That’s why fuses sound better in one direction, worse in the other direction in AC circuits and DC circuits. As Old Blue Eyes sez, that’s life.

Just for the record, 60 Hz AC changes polarity and consequently direction 120 times per second. During each 60 Hz cycle the waveform goes from negative to positive and also from positive to negative.

However energy is conveyed in only one direction, from source to load, putting aside reflection effects that occur mainly at RF frequencies.

you made my morning. sadly, being gluten sensitive, my chances of discovery are lessened.

Let's remember to clean the fuses. Contact cleaner (what brand?), Spit Shine? What to eat or how long to fast prior to spit shine? Dry with what cloth? Circular wipe? Direction, relative to the equator!
