Of course, the real interesting thing in the fuse measurements was that listening tests correlated to measurements, i.e., the best sounding directional was ALWAYS the direction with least resistance.
A question: Where do you see that?
The only reference to listening tests I see in the HiFi Tuning paper is the following statement, which has nothing to do with directionality:
For DC applications it ́s recommended to use the solder type fuse or the cryogenically treated fuses from HiFi-Tuning Germany.
The drop in resistance up to the factor of 8 is clearly measurable and also could be detected in listening test.

>>>>>Al, that’s a good question, but 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. That’s why they mark their fuses with that diode symbol, so the user can experiment and find out which direction sounds best. So, of course HiFi Tuning obviously believes that the measured data supports their position. Otherwise they would not have published the data. And that the fuse direction that exhibits the lower value for resistance (I.e., higher conductivity) would be the best sounding direction. In their conclusion, they state,
"The measurements done so far showed some measurable differences between fuse,
but didn ́t explain completely the sonic differences between fuses."
That statement shows they believe the directionality measurements correlate with sonic differences (but do not necessarily explain the large sonic differences they heard). As I’ve already indicated many times, there are other variables involved with fuse sonics, fuse directionality is not the only variable. No one ever suggested directionality was the only or even primary variable. One need look no further than the design of many modern aftermarket fuses such as Audio Magic Beeswax fuse and Synergistic Research Black (I.e, Graphene) fuse to see that other factors are involved and addressed, and HiFi Tuning gold and silver fuses and cryo’d fuses obviously address other factors, too.
