Geoffkait: why on Earth would they have even had someone test fuses if not to prove - or at least show evidence - that fuses in general are directional and that HiFi Tuning fuses exhibited better measured characteristics in terms of conductivity than other high end fuses of that time period as well as stock fuses? HiFi Tuning believes in fuse and wire directionality.
A much simpler answer is that they want your money and the way they are getting it is by making gold-plated fuses. The marketing rhetoric is of course to separate them from the much less expensive gold plated fuses used in cars.
Now, you’re just being silly. If you have a better mousetrap why not advertise it? It’s the difference between reality and hyperbole. Nothing more than that. Naysayers always demand tests and harrumph, harrumph. Here’s someone who actually provided tests - the only ones as far as I can tell - and still they moan and demand and grouse. 😛
