I think that the sonic effect of replacing fuses depends on the particular circuit design, and the position of the fuse in that circuit. When the entire audio signal passes thru a fuse, the effect of the fuse on sound quality can be marked. In the Rogue Cronus Magnum II, Synergistic fuses greatly improved the sound quality - more than interconnects and power cords.
Experiment if you can afford the fuses - not cheap though.
