Synergistic Red Fuse ...

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.

Allow me to draw your attention to some of the conclusions found on the data sheets of HiFi Tuning, manufacturer of the HiFi Tuning fuses.

o Aftermarket fuses gave the best results for conductivity and HiFi Tuning cryogenically treated fuses gave the best results of all fuses tested.

o Aftermarket fuses almost always tested and sounded better than stock fuses. [Editor’s note: a stock fuse in the correct direction could sound better than an aftermarket fuse in the wrong direction and a stock fuse that’s been cryogenically treated could sound better than an aftermarket fuse that hasn’t been treated.]

o Fuses with smaller dimensions were found to sound better than fuses of the same value with larger dimensions.

o Fuses (both stock and aftermarket) from different manufacturers sounded different. We attribute that sonic difference to different materials used in the due wire and contact points and or different purity of the same material in the various fuses tested. The (obvious) differences in sonic results of various fuses of the same value could not be completely explained by the measurements, which were relatively small.

o There is a measureable difference in directionality of fuses of around 5% for all types of fuses.

have a nice new year

If it's measurable can you provide the measurements please?
