Synergistic Red Fuse ...

sayles- I just put two SR BLACK into my 5400 es too. When you say arrows? Can you explain? I put it them in position with the writing going down, facing the front of the unit, as if each fuse was a book on a shelf. Seemed the best sound for me. They replaced two furutechs. Awesome. 

I'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.  

Like others, I am really surprised how much difference these fuses can make.  Where these fuses make a difference, the difference is substantial.  

Geoffkait: After all that was YOUR claim - that a straight wire bypass would outperform an aftermarket fuse.

To which Georgelofi responded,

"Technically YES, if one is a technician and a betting man you would put your money on the "temporary" 10mm piece of copper wire everytime, unless one is a voodoo’ist then your a believer that pigs can fly. That’s why this sort of thing is not getting any reco in the "Tech Talk" forum and should not be given it as well. 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."

well, actually maybe YES for a stock fuse or perhaps for an aftermarket fuse of yore. But, as I already explained fuses have evolved. They’re like the Alien. Many modern (I.e., aftermarket) fuses address a wide range of problems, problems that exist with a stock fuse AND with a copper wire bypass. I am going out on a limb here but I’m guessing that techs don’t believe in wire directionality, do they? I'm getting the feeling techs might be a couple paradigm shifts behind the curve. Anyway, to summarize, the real answer is NO.

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.
