Fuses fuses fuses

"East is east and west is west and never the twain shall meet" Geoff, well stated and true. Terry9 I can tell you that the upgrade fuses are clearly effective in my system. However you’d likely remain skeptical based on your own inherent bias and preformed opinion. I understand that and it’s okay with me. East vs west 😊. I will agree with you regarding spending money where you believe it’s appropriate and justified. That’s what I did and am very pleased. This criteria will naturally vary amongst us all. If we're both satisfied with our respective audio systems, all is good in the final analysis.

Hello Terry9,
Deception can of course work in both directions (pun intended). One can convince themselves they hear something that may or may not exist. Conversely one can convince themselves that there can’t possibly be a difference to hear based on any manner of preconceived notions. Science is indeed wonderful but is "still" woeful" in explaining the very complex human hearing mechanism/pathways. What the ear can detect is far ahead and of what man can currently measure and quantify. We’ll get there one day.

Zavato,
I understand,  honestly there will be various descriptions of what different listeners have heard.  Your experience may in fact be quite different from mine.  I've no desire to convince or persuade anyone of anything as it is a fruitless effort.  I just state my individual listening experience and others can accept or reject as they see fit. Most folks will appreciate the reality that a topic such as this yields plenty of opinions and no universal consensus.

The placement of the fuses regarding direction  is random.  In my DAC and Line Stage the initial placement was better than when I subsequently reversed them. With my mono block amplifiers reversing the initial placement led to an improved sound.  The point is that it's truly random choice and both directions need to be heard.

My experience with the SR Black fuses is similar to those of nonoise with his fuses. I listened to the fuses placed in one direction and then reversed this direction. Without fail there’s an undeniable change in the sound, not necessarily good vs bad, but "different ". One direction was very clear and "locked in ", the other had an "out of phase " character.

This contrast was heard with my DAC, Line Stage and amplifier. A good friend of mine had the same results in his system with completely different components. He and I heard this with SR and his Audio Horizon fuses. The bottom line was consistent differences in sonic character based on fuse direction.

I am unable to provide a satisfying technical explanation ànd won’t make àn attempt to do so. Al, Ralph and others make strong and compelling arguments why fuses "shouldn’t" behave in a directional manner. I respect their opinions very much. At the end of the day I simply listen and report what I have heard with or without a satisfactory technical explanation to accompany it.

Why do I hear a difference? I don’t know.
Do I hear a difference based on fuse direction placement? Unequivocally yes. As with all things involving audio YMMV 😊.
