Do you understand electronics ?
Inductance and capacitance matter when you are pulling current. Without current flow neither one of them will do shit. Their effect is a function of impedance.
I remember when Heathkit decided to put the speaker fuses inside the feedback loop because at extremely low frequencies the intermittent heating of the fuse element would cause odd order harmonic distortion.
No, what you do is put the fuses where they are not in the audio path at all. And if you are in a DAC you aren't pulling enough current to make any difference. Only in amps is where this comes in. And rarely.
In amps, the fuses need to be placed where they do not affect the sound. For example if using common collector configuration with a complementary pair with the output coming off the emitters, you can fuse the collectors all you want. But if you put them on the emitters it could affect the sound.
It is a matter of proper design, and this is why some companies achieve.
The fuse should not matter. If it does the engineer screwed up.
Know what ? Analog engineers are extremely hard to come by these days, worldwide. Companies keep throwing money at the old geezers and they pick and choose their jobs. And the old geezers would not mind hiring some new talent but cannot find it. They don't really want to work anymore they got it made, but then here is ten grand and they got the design doe in two hours and the prototype made in two days. That is pretty hard to pass up.
Bottom line, I don't know how to tell you how to learn electronics if you want to. It is extremely hard to teach real electronics. The concepts of current and all that are so foreign to most people, and they have no background i science, at least in this country. Even in college, it's like everyone wants to be an investment banker.
Electronics is VERY hard to teach. I don't even try anymore.

Yes, but even if it doesn't make any sense at all, some here will hear a difference.
