High Quality Fuses: Real Gains?

All:

I'm generally suspicious of "tweaks" but I had an interesting conversation with a service representative from one of the major audiophile companies about the potential benefits of replacing stock fuses with higher quality ones like the HiFi Tuning brand. I thought he would dismiss the potential gains of using an "audiophile" fuse but he affirmed that they might actually produce audible improvements since all the current must travel through this junction. He also admitted that the stock fuses they use are pretty ordinary throwaways. So, have any of you used these and if so what were the results? Are there brands other than HiFi Tuning that are worth considering? I should have probably checked the archives so if this has been debated already sorry to bring it up.
