Synergistic Red Fuse ...

brownsfan1,122 posts03-19-2016 5:30amI’ve got about 50 hours on the two SR blacks I installed in my ModWright Sony HAPZ1 now. Last night, I removed them and put the stock fuse back in. The effect was exactly the same as A/B’ing stock vs SR black in my Coincident CSL. The sound went two dimensional with loss of dynamics and a step backwards in complexity of harmonics. I reinstalled the fuses one at a time, and found that the fuse serving the hard drive was far more important than the fuse labeled "mains." Next up I am either going to buy one more 3.15 A slo, and fuse my Coincident Franks with the SR Blacks leaving the stock fuse in the mains slot, or else buy a fuse for my MW PS 9.0 power supply.

Brownsfan, what direction did you install the two SR black fuses in your MW Sony HAPZ1?  Facing the unit from the front, Is the fuse in the front or rear serves the hard drive?   My board doesn't indicate "mains" ... both have same label.

i suggest that nstalling the two T800mAL SR Black fuses into a Sony XA-5400ES deck one should hear a better result with when when the SR (red) logo "arrow" is facing the front of the deck. Or in other words, the fuses should read like illustrated:

BACK OF DECK< SR ----> >FRONT OF DECK

agreement with this direction is also documented here:

Happy Listening!

georgelofi, dear sir, you and I will perhaps never agree because in you mind set, a fact, is not a fact until human consciousness and agreement formally except an idea. In my mind, this can be pure madness and so would be arguing this subject as I am scientifically, admittedly, ill equipped.

The problem with this fundamental miss step though is we (and our science) is often wrong until it is right. Commonly the human condition can't see outside the small box it has constructed to feel comfortable. This is not to say, that that is all that exists. But it is our ignorance to believe in such limits. Just like with psychoacoustics or our terribly short audio memory, this mindset can be fooled. History is filled with pseudoscience proven wrong once an enlightened soul happens to observe and validate a phenomenon by looking at it in a way others have not. This is not voodoo, but many have been persecuted or worse for not thinking like the common excepted beliefs of a particular time, deemed as fact. I realize it is scary to question commonly held beliefs, some perhaps "seudo-facts".

Yet I'm too busy enjoying my life and the music to argue with you. If you chose to be more interested in stamping out counterintuitive thinking "your voodoo" on public audio threads, that is your choice. Though it is a burden many of us will simply have to bear. I would only suggest that you consider "science" with the knowledge of a old man but, with the wonder and possibility of a child. I contend you will not only be happier, but may well leave the opportunity to actually discover or advance something in our science.

In this case, I truly enjoy what Caelin Gabriel speaks of at the closing of this interview as I feel it is so spot on and I find it speaks well to this discussion.

Happy Listening, ah?!

Unless these fuses are resistive, capacitive, or inductive in nature, then there are grounds for a technical discussion on them, and if they are any of these then they can only be detrimental to performance in the power supply chain.

It would be interesting if someone who has some of these fuses and also has a good quality digital multimeter would measure their resistances. "Good quality" includes the ability to resolve fractions of an ohm.

If anyone does this, for the result to be meaningful the reading that is obtained by touching the two probe tips directly together should be subtracted out, if it is not zero.

I’ve pondered the possibility that unusually high resistance might account for the differences that have been reported, compared to stock fuses. It seems unlikely for several reasons, including the consistently positive direction of the differences that have been reported, the directionality that has been reported, and the fact that the fuses would probably be getting warm or hot if their resistance was great enough to drop significant voltage.  But still, it would be interesting if someone could make those measurements, if only because it may rule out a possible contributor to the differences.

pretty sure we’ve covered this question you’re pondering before. See link below to some data on HiFi Tuning’s website for resistance of various fuses - several of their own, stock fuses and others - backwards, forwards, cryo’d, what have you. No sense torturing yourself pondering. ;-)
