Silver adds a little more shine, neutrality and definition.
Whereas gold adds a bit of warmth, boosts bass a bit and is a bit more forgiving.
There are fuses with one side silvered, and the other side golden.
Are they the best of two worlds?

How can you identify exactly which one is L or N? Do we have to concern about the fuse direction?
Good question!

To be 100% sure that the right polarity is guaranteed from the wall outlet over the power strip to the device, you need one of these phase tester:

You call a technician who checks the polarity of the wall outlet with the phase tester.

Insert phase tester into the wall outlet and press the red button. Where the light of phase tester goes on, this is your L phase (Live Wire).
Mark the L phase with a dot.


Do the same with the power strip.

Some power strips have already markings for the L phase.
Nevertheless, you must check again the polarity of the power strip if it coincides with the markings.

If polarity is reversed, then unplug the strip from the wall and twist the Shucko plug by 180 degree. Now polarity should coincides with markings.

Now the power strip has the right polarity.

Go to the wall outlet where the power strip is plugged in, and assign/transfer the marking from the wall outlet to the schucko plug of power strip. So the next time you unplug and plug again, you have the right polarity.

Do the same procedure with the power cords from the power strip to your devices.

By having the right polarity from the wall outlet to your devices you can increase sound quality.


If you have a fuse with direction

Insert the fuse into the fuse holder with the right direction

So the arrow on gustard Upgrade fuse is supposed to Pointe up?

We did not tell you to take a 3.15A without a reason.

Sorry for asking and possibly "ruin the party", but how could a fancy and silly expensive fuse change the sound?

Being straight forward:
How can this not be anything else than placebo?

The fuse is neither in the digital, nor the analog path. It doesn't limit the current or voltage to the PSU within its spec either.

Now, in the highly unlikely case where the engineers / manufacturer selected a too weak fuse, a higher spec'ed would help preventing the unit from blowing the fuse, but we don't have such a scenario here, since noone has blown the stock fuse during normal use.

In short, how can boutique fuses not be anything else than "snake oil"?

If there is a scientific / electrical explanation for it, I would love to learn and become wiser. :-)

Bro. to be helped effectively, need to post that question on the Cables, Power, Tweaks, Speakers, Accessories section.
Specifically on this thred: https://www.head-fi.org/threads/audio-grade-fuses.419939/
We have a lot of side topics around this R26 thread already: clocks, ethernet, shielding, cables, DAC architecture etc. etc..
Don't want this thread to be flooded another with fuses..

There is no doubting the improvement made by a fuse upgrade. Try it yourself, only then are you qualified to voice an opinion! Not everything can be measured, science can only take us so far, but our ears are the final arbiter.

@LarsHP Many fuses can condition the AC that comes into the unit, causing sonic improvements. This comes from treated fuse wires, and piezoelectric materials that can surround the fuse wire. There are lots of recipes out there. And the best way to answer the question is to test it yourself. There are many affordable options.
