We Need A Separate Forum for Fuses

Doug they are not gift, And no plans to try.Very expensive..

>>>>Actually, sir, they are not expensive. That’s an Old Wives Tale. There are more than a few high end fuses around 20 bucks and a bunch under 50 bucks. Create Fuse from China is 5 bucks. Check out The Cable Company’s fuse page and see what I mean. Even some stock fuses have high end versions now. Gosh, what’s the world coming to? 🙄

In my Rogue Cronus Magnum Ii, SR fuses in the tube circuit make a very noticeable improvement in SQ. Stands to reason because the entire audio signal, at very low level, passes through each fuse. An extremely thin wire that is meant to melt under excess load is probably not well suited to passing 10 octaves of delicate music signal without altering phase or amplitude for some frequencies.
An audio circuit bears no resemblance to an appliance where the main purpose is to generate random heat energy, of course.

Uh, let’s be fair. The full AC signal passes through fuses located where the AC enters the component. That’s not (rpt not) a very low level signal. Or even a low level signal. You could also say fuses located in speakers, where the signal enters them, does not (rpt not) pass a very low level audio signal. Gee, you could almost say fuses are not really required for very low level signals since low level signals can’t harm the electronics. 😛

Geoffkait,
I guess I don’t understand your comments. The fuses are there to protect the circuit in case of component failure, not to protect against the low level music signal. The effect on the music signal is an unintended consequence - which could be large or small dependind on the circuit and fuse design.
At any rate, in my system I hear a definite improvement by “upgrading” the fuses through which the audio signal flows. Replacing the main power fuse does not seem to improve the sound.
