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.
