I should amend my post to note that SR Black fuses are more like 40 times the price of standard fare. Note that geoffkait’s HiFi tuning info post easily fails the logic smell test as it includes the same "directionality" nonsense along with references to "data" with no actual data…5%? Really? It’s amazing that a firm such as HiFi Tuning while selling a product would support such products…who knew? I realize many here feel these things help the mojo of their gear somehow, but the lack of any explanation of WHY they help a power supply improve its function and the downstream components (and apparently all aspects of the listening experience including but not limited to soundstage, cello tone, ear wax reduction, and Jo Mama, as long as break-in time and directionality issues are considered) beyond mere speculation is troubling. Or consumer fraud. In any case the fuse rating issue remains a dangerous thing that even "Fusers" may want to think about, as it was my understanding that UL approval (Or maybe Good Housekeeping?) keeps things safe with pesky electrical failure safety testing on everything from toasters to Pass Labs. I might be wrong about that, but I like my fuses to be the proper value with zero wiggle room ("Fuse blew? Try one rated higher, insurance will rebuild your house after the fire so what’s the big deal?"). Now I can sit back and wait for my big fat promotional check from Littlefuse…oh yeah…uh huh...
