Synergistic Red Fuse ...

So, again, my question remains unanswered, although obviously I still think it's relevant and very basic. Most manufacturers of "audiophile" tweak products like gear racks, cables, tube dampers, spiky or rubbery feet, etc., will be happy to explain the whys and wherefores of what the product actually technically does, even if the design theories are a little sketchy or controversial. Fuses not so much, or in the case of SR's fuses, nada. I've tried 'em, they don't do anything sonically at 8 times the price of standard issue fuses, and they're somewhat dangerous. 

at 8 times the price of standard issue fuses

Wolf, you left a zero off of your price comparison factor.  I pay about $1.50 for Cooper/Bussmann glass fuses or, if I splurge, about $3 for their ceramic body fuses. 

Al, I agree with you about the whole fuse thing......

While I agree technically with Almarg, I still think that tiny little wire does indeed impact the power supply in terms of sound. Like many things in audio the raw data does not explain it all. I have bypassed fuses, used circuit breaker on/off switches in place of fuses and in each instance heard obvious sound improvement. 

"Like many things in audio the raw data does not explain it all"
Bill that’s a reality I accepted long ago due to repeated listening encounters that defied "conventional wisdom " based on available technical specifications. Audio truly is a mixture of science and  engineering principles but art as well. Certainty I believe the higher % of contribution is the former, yet enough art factors in to be undeniably relevant. By art I'm referring to those factors that clearly influence what we hear but have no  (as of now) technical validity to support them.

I have a healthy curiosity about how and why things/products do what they do but not to the degree to prevent me from judging merit/worth based on listening. If someone asserts there’s no difference sonically between a 1 dollar and 100 dollar fuses it’d be foolish to buy the expensive fuse (obviously).

I lack any desire to convince others who dismiss my and other listeners very positive experiences with premium quality fuses, to each their own, it’s actually that simple. Not everyone will have the same outcome as I and other participants here have had and that’s nothing unusual . I can only report my listening experiences and people are free to accept or reject them. It doesn’t by any means alter what I have heard in my system and that of other listeners.

" Audio truly is a mixture of science and engineering principles but art as well."

Well said Sir Charles.

The art you mention can only be gained from experience ( hard work, trial and error and a fanatical desire to succeed ). I would estimate that 35% of success in audio is based on book learning, while 65% is attributable to experience. Book learning is essential and provides the foundation for development but it is the additional specialized knowledge gained from experience (blood, sweat and tears)  in the field that elevates the winners.
