Mac48025, the answer to your question as to why the SR Red and Black Quantum fuses
can't improve the sound of a component :--- as previously stated in this thread-
"Obviously anyone 'touting' theses Synergistic Red Quantum (or black) fuses has never taken a look at all the wiring 'after the fuse' - within the device. If they did they'd see all sorts of
Pieces of wire, longer than the fuse, connecting various items." As wolf_garcia stated; if your fuse is old simply replacing it with a new one will give the same benefit as an SR fuse.
Same for highly touted "benefit" of the directionality of said fuses.
No reputable manufacturer (I'm aware of) of components these fuses are suggested for, promote their products for the "directionality of the wiring".. That moots the point about the "value" of the fuse directionality, again because of the various wires following the fuse.
So I remain aligned with the Healthy Skeptic-wolf_garcia - when he says
" the promotion of a nonsensical, inexplicable, expensive and utterly useless fuse "upgrade" will garner my ire as long as this thread continues".
Particularly with the "unending 'incremental' upgrades" type of changes (Chris Connaker referred to such types of changes "
I've been disappointed in the past to learn of manufacturers who release "Mark II" of a product only because a single internal component of the original version is no longer available. It's just as disappointing to see the unaware spend hard-earned money on such an upgrade." ; rather nicely put I feel. See it here' in the first paragraph. -
