fuse question

It seems generally accepted that the quality and construction properties of a power fuse makes a difference in sound quality, but what about the quality of the fuseholder itself? I see on many high-priced amps that the push-in spring-loaded fuse holder is obviously not audiophile grade material. Isn't this affecting the sound just as much as an inferior fuse?
What about if the leads were soldered directly to the fuse-being careful to maintain fuse integrity,of course- or, are there audiophile grade fusible links which could replace the fuse ass'y? Any ideas?
