What direction should Hi Fi tune fuse be installed

Al & Geoff,

My intention wasn't to stir a pot that's already messy.

The review thread I quoted from may have been less than rigorous in terms of design and the question of replication is ambiguous.

If the reader wishes, I recommend going through a research study done by GECOM Technologies GmbH that addresses such areas as resistance, noise, and voltage drops. The section on resistance shows measurements orienting the various fuses tested in both directions.

There are explanation and summary sections for the tests performed although the raw data and testing methodologies will be of interest to some, I'm sure.

Anyway, here's the link to the tests. Please note that you can download a PDF of the tests as well.

Thanks, Joe. It so happens that I had provided my comments regarding that paper in another fuse-related thread, about two years ago.

Best regards,

Thank God I don't know much about electronics. If I did I might trust my ears less and not be willing to experiment with fuse direction.

I found with my HiFi Tuning Supreme fuses that they do make a nice improvement. My ears tell me that they do sound better in one direction over the other. Which is good so what I don't know about electronics doesn't interfere what what my ears don't have to understand why one direction sounds obviously better than the other.

Almarg, I remember reading your response. I would take exception to the use of the word, "insignificant." This word does have one quite specific definition in sampling theory, but generally it is just dismissive. Since you are not talking about random samples, I guess you mean it to be dismissive. I see no real way to make it so.
