You take your chances…although I’ve been ranting seemingly for ages against SR’s overpriced examples of possibly dangerous audio tomfoolery, and have occasionally posed the still unanswered question, "why, and how, were they designed to do whatever they do?", the safety issue (as well as the fuse directionality myth and ridiculous imagined sonic benefit claims, as well as obvious commercial promotion by thin skinned "shill seekers") seems unignorable, which isn’t to say it won’t be ignored. "Damn the torpedoes, I want my tonally accurate cellos!" You can claim until the cows come home (they may never come home by the way) that special shoe laces make you walk better, or cryonically treated valve stem caps make your car corner faster, but logic may prevail when reports come in that the laces come untied causing you to fall over, and the valve stems explode causing you to crash. Hypothetically…or maybe not as regards SR fuses. Details schmeetails!
