I found the HiFi fuses to be a nice improvement. Not as much as upgrading the power cord but about as much as changing an interconnect. Go for it!
Hifi Tuning Fuses
Does anyone here have any impressions on the Hifi tuning fuses and how they possitively or negatively affected components in their system? According to some audio enthusiasts, installing premium grade fuses in preampss, amps, phono etc make a significant improvement in the overall sound. Any comments are most welcome since I'm considering this relatively inexpensive tweak.
