Hi Blueranger
I've heard the same thing from other more experienced audiophiles as well. They told me before I start spending funds on the expensive audiophile type fuses they told me to clean the fuse holder and fuses themselves. If possible I use metal polish on the fuse holders and fuses themselves and then spray them down with deoxit cleaner. I was told to use as much elbow grease as possible to get the fuses clean. I believe I heard a difference but am unsure as when I did this I made all sorts of tweaks at the same time. I did save a bunch of money though. The polish and cleaners weren't anywhere near as expensive as the fuses I needed.
