Anyone used these audio ceramic slow blow fuses from Littlefuse?

While perusing the fuse offerings at Mouser Electronics I noticed these audio/medical fuses priced at around $9.00 US. As someone who has been reluctant to spend the price for the highest priced audiophile fuses, these more reasonably priced offerings caught my eye. Just curious if anyone has had occasion to try them and form an opinion. I must say the attention to quality control, ratings specifications, and published testing results make these look more appealing to me than the rather vague specs of many "audiophile" fuses.
