noromance, I assure you that my understanding of the process of electronic amplification is as complete or incomplete as yours. We just chose different words to describe the process. Nor did I say (or think) that the signal is "ushered" anywhere. Nor does your comment contradict my point that the fuse placed on the power transformer primary does not pass the audio signal. Let’s just leave it be.
I don’t know why I got so lathered up about fuses back in November, 2019. I should know better than to argue over tweaks, and in fact I thought I did know better long before the end of 2019. If you like it, it’s good. I will only add that if fuses are so critical to overall sound quality, then the fuseholder must assume equal importance. Wouldn’t putting a $150-fuse in the typical cheap pot metal fuseholder to be found on the back panel of even expensive components be an exercise in wishful thinking? Yet there is not much literature about fuseholders. Nor are there many boutique fuseholders from which to choose. I settled on Acme silver-plated cryo-treated fuses in an Acme fuseholder, which has silver-plated contact surfaces, where I am concerned that a fuse might make a sonic difference, as in my OTL amplifiers where there is a fuse actually for real in the signal path. Acme fuses and fuseholders are not crazily priced and seem fine. Enough said, unless you or someone else wants to discuss this off-topic further.
Also, I think I made the point back in 2019: I do NOT deny that ICs and power cords can affect the sound. But for power cords, I have found by experience that, for me anyway, the main factors are current-carrying capacity and low characteristic impedance, not quantum effects or any hoo-doo voodoo.
