If I wanted to know the difference that bad I'd just jump the fuse block.Didn't you see the link to where Paul McGowan and a friend designed a wonderful sounding amp only to have it suck when they incorporated the fuse? It completely messed with the sound. Even gold plating the holder didn't help much. They didn't try aftermarket fuses back then (it was in the 80's). It never sounded as good once the fuse was added. The fuse is the bottleneck. Some amp designers figured it out way before this discussion came along.
All the best,
