Default Sound of 220V~ fuses ???

Over the last days i wondered how well my system is sounding. Totally precise
and clean i can´t remember it was that good before. Just made me wonder somehow.
Today i had the normal small talk about everything with my dad and at random he
talked about the short-circuit he had at the beginning of the week. He peplaced
the fuse that feeds my system, too.

Am i totally stupid now or has anybody same experiences??

I´ll go downtown for a drink now and will wonder myself about this till late at night
If time permits - stuff some parsley in your ears and listen how it grows!

Well, if the fuse had a bad connection to the circuit, I could make a noticeable difference in some cases.

If the circuit is normally under a high load situation, then it will show small problems because of bad connections in the fuses or wiring.

I know that this is weird, but I had found bad connections to wires on my outlet in the bedroom where my stereo is. In Canada, most of the outlets we have are built with two options for connecting wires. Either you can use screws to tighten onto the wires, or you have a little hole to shove the wire into that bites it with a metal strip. The screw option is obviousely much better because it offers far more surface area and a much tighter connection. After re-stipping the almost 40 year old wires and re-attaching the outlet, which had been push-connected instead of screwed, the connection was far better.

The stereo did seem to hace a nicer feel to it for sure. And then later I installed a hospital grade outlet in the room, which didn't seem to make much more difference, but I'm happy cause it's so much harder to accidentally remove the plug.

In another situation, I found that by powering the stereo by battery, I could achieve a much cleaner noise floor. I put the whole setup on lead acid batteries with an inverter and it was excellent. Also nice for when the power goes out.

It may well be more psychological than anything else, but once a year, I always take all my mains plugs apart, and clean all the pins and fuses/holders with Brasso metal polish. It certainly seems to make a difference!

Obviously others have had similar experiences at least:

Note however, unless your "or" is intended as exclusive or
it is still possible that you are stupid, according to the rules
of logic.

(Just to prevent misunderstandings, I am not trying to
claim that you are stupid).

BTW, I love your signature quote. I have never had a chance
to try it out, though. I like parsley too much, so I have a
tendency to eat it before I get a chance to try it in my ears.

While you're at it, I suggest cleaning all the RCA connectors, or whatever is used, both male and female counterparts.
Fuse holders, open and closed types...in short anything that could have contact resistance.

Have a listen before and after, you may well be in for a nice surprise.
