Perhaps you should have tried the Beeswax variety?Those don’t blow, but they buzz.
So done with audiophile fuses
The journey started with a medium priced ($50) fuse in my power supply. A failed rectifier tube blew that one out. Not a fuse problem. Next up was a blue fuse in my pre amp. It blew and was not caused by a pre amp problem. Apparently they sometimes are more sensitive and it was replaced by an orange fuse two values higher. Things were going along fine. I replaced the pre amp with a newer version of the pre amp and it has the same fuse value. Five months latter (today) I turn on the pre amp and nothing. it's a five month old pre amp so I suspected that it was the fuse. Sure enough, I replaced it with a ceramic Littelfuse of the lower correct value it works fine. No more wasting my money on unstable fuses for me.

They weren't necessarily engineers at Yamaha but "sound tuning guys" who reportedly believed they heard a difference between different basic (non-audiophile) fuses, when they were auditioning OEM sources for fuses in their AV receivers. While that is information to ponder, it doesn't rise to the level that would lead me to conclude that expensive audiophile fuses actually "improve" the sound of anything. The SR site lists the materials used in their fuses on their website and the ceramic body, silica filling, brass nickel plated end cap contacts, and metal filament are all pretty standard stuff.
I guess what makes them stand out are the (flavors du jour) quantum treatment, molecular realignment process, UEF treatment, and Graphene. I own and use some but really cannot understand what all the fuss is about, except that they cost a lot. For only $175, you can get the Audio Magic beeswax fuse, which appears to be simply a standard Littelfuse or Cooper Bussmann fuse that is injected with beeswax. |
A fuse, according to the manual, is just there as a safety device and shouldn't have any effect on the sound. And yet it did.That, of course, is the perplexing part. While I don't Know and won’t say that fuses have no effect whatsoever on the sound of a system, I still can’t buy that the magnitude of the effect (or improvement, or whatever) would be great enough to make me want to spend big money on a fuse. |
What is Ayre now using instead of fuses? I googled them and came up with a picture of the back of the KX-R and it shows a standard inlet IEC with integrated fuse. |
