To all those here that are thinking of blowing a $160 on a $1 fuse, don’t!!.
Don’t get sucked into this snake oil.
Even the fuse manufacturers won’t post here and back the claims made by these fusers for liability reasons.
The only reason a change of fuse "could" make a sonic difference, is if the old fuse (a $1 or $160) one has seen too many turn-on cycles, as this always stresses the fuse with current surge, causing them to crystallize and harden "over time" re the time laps pics of the same $1 fuse, in two different cases below.
This "could" make them sound different. The fix is just to replace the $1 fuse with the same new $1 fuse, instead of blowing $160 on a fancy looking voodoo fuse.
Left to right aging same fuse.
